Mobile Network Layer
Mobile Network Layer protocols and mechanisms allow nodes to change their point of attachment to different networks while maintaining ongoing communication. Key concepts include:
- Mobile IP adds mobility support to IP, allowing nodes to use the same IP address even when changing networks. It relies on home agents and care-of addresses.
- Registration allows mobile nodes to inform their home agent of their current location when visiting foreign networks. Tunneling and encapsulation techniques are used to forward packets to mobile nodes' current locations.
- Various routing protocols like DSDV have been developed for mobile ad hoc networks which have no fixed infrastructure and dynamic topologies.
AODV routing protocol
The document discusses several routing protocols for mobile ad hoc networks:
- DSR allows nodes to cache and share routing information for more efficient routing but has larger packet headers due to source routing. AODV uses only next hop information, keeping routing tables smaller.
- Both protocols use route discovery and maintenance, but AODV proactively refreshes routes while DSR reacts to failures. AODV also uses sequence numbers to prevent loops and choose fresher routes.
- Overall, DSR is better for networks where routes change infrequently while AODV scales better and maintains only active routes, at the cost of higher routing overhead during route discovery. Security remains a challenge for both protocols.
Routing algorithm
The network layer is responsible for routing packets from the source to destination. The routing algorithm is the piece of software that decides where a packet goes next (e.g., which output line, or which node on a broadcast channel).For connectionless networks, the routing decision is made for each datagram. For connection-oriented networks, the decision is made once, at circuit setup time.
Routing Issues
The routing algorithm must deal with the following issues:
Correctness and simplicity: networks are never taken down; individual parts (e.g., links, routers) may fail, but the whole network should not.
Stability: if a link or router fails, how much time elapses before the remaining routers recognize the topology change? (Some never do..)
Fairness and optimality: an inherently intractable problem. Definition of optimality usually doesn't consider fairness. Do we want to maximize channel usage? Minimize average delay?
When we look at routing in detail, we'll consider both adaptive--those that take current traffic and topology into consideration--and nonadaptive algorithms.
TCP over wireless slides
The document discusses various protocols and approaches for improving the performance of TCP over wireless networks. It notes that wireless networks have higher bit error rates, lower bandwidth, and mobility issues compared to wired networks. Several protocols are described that aim to distinguish wireless losses from congestion losses to avoid unnecessary TCP reactions:
- Indirect TCP splits the connection and handles losses locally at the base station. Snoop caches packets at the base station for retransmission.
- Mobile TCP further splits the connection and has the base station defer acknowledgments. It can also inform the sender about handoffs versus interface switches.
- Multiple acknowledgments uses two types of ACKs to isolate the wireless and wired portions of the network.

Geographic Routing in WSN
This document summarizes geographical routing in wireless sensor networks. It begins with an introduction to geographic routing protocols, which route packets based on the geographic position of nodes rather than their network addresses. It then discusses several specific geographic routing protocols, including Greedy Perimeter Stateless Routing (GPSR) and Geographical and Energy Aware Routing (GEAR). The document also covers topics like how nodes obtain location information, security issues in geographic routing like the Sybil attack, and concludes that geographic routing can enable scalable and energy-efficient routing in wireless sensor networks.
CSGR(cluster switch gateway routing)
This document discusses clustering-based ad hoc routing protocols. It introduces the Clusterhead Gateway Switch Routing (CSGR) protocol, which uses a hierarchical network topology with mobile nodes grouped into clusters led by cluster heads. Each node maintains a cluster member table mapping nodes to cluster heads and a routing table to select the next hop towards the destination cluster head. The Least Cluster Change algorithm aims to minimize changes to cluster heads. The document provides an example routing from node 1 to node 12 and compares CSGR to the table-driven DSDV protocol.
Transport layer protocol
The document discusses the differences between packets and frames, and provides details on the transport layer. It explains that the transport layer is responsible for process-to-process delivery and uses port numbers for addressing. Connection-oriented protocols like TCP use three-way handshaking for connection establishment and termination, and implement flow and error control using mechanisms like sliding windows. Connectionless protocols like UDP are simpler but unreliable, treating each packet independently.

Lecture 11 14. Adhoc routing protocols cont..
The document discusses on-demand driven reactive routing protocols. It provides an overview of table-driven vs on-demand routing protocols and describes two popular on-demand protocols - Dynamic Source Routing (DSR) and Ad Hoc On-Demand Distance Vector Routing (AODV) in detail. DSR uses source routing by adding the complete route to packet headers. AODV maintains routing tables at nodes and relies on dynamically establishing next hop information for routes.
Dsdv
DSDV is a proactive routing protocol that uses destination sequence numbers to ensure loop-free routing in mobile ad hoc networks. Each node maintains a routing table with destination addresses, next hops, metrics, and sequence numbers. Nodes periodically broadcast their full routing tables, and also broadcast updates immediately after changes to avoid counting to infinity problems. DSDV aims to limit unnecessary route advertisements through a mechanism to dampen fluctuations in routing tables.
Multiple Access Protocal
Fast Ethernet increased the bandwidth of standard Ethernet from 10 Mbps to 100 Mbps. It used the same CSMA/CD access method and frame format as standard Ethernet but with some changes to address the higher speed. Fast Ethernet was implemented over twisted pair cables using 100BASE-TX or over fiber optic cables using 100BASE-FX. The increased speed enabled Fast Ethernet to compete with other high-speed LAN technologies of the time like FDDI.

Mobile Transport layer
This document discusses various approaches to improving TCP performance over mobile networks. It describes Indirect TCP, Snooping TCP, Mobile TCP, optimizations like fast retransmit/recovery and transmission freezing, and transaction-oriented TCP. Each approach is summarized in terms of its key mechanisms, advantages, and disadvantages. Overall, the document evaluates different ways TCP has been adapted to better support mobility and address challenges like frequent disconnections, packet losses during handovers, and high bit error rates over wireless links.
Zone Routing Protocol
ZRP divides routing into intrazone and interzone routing. Intrazone routing uses a proactive approach to route packets within a node's routing zone. Interzone routing uses a reactive approach where the source node sends route requests to peripheral nodes when the destination is outside its zone. The optimal zone radius depends on factors like mobility and query rates, with smaller radii preferred for higher mobility. ZRP aims to reduce routing overhead through techniques like restricting floods and maintaining multiple routes.
UMTS, Introduction.
Universal mobile telecommunication System (UMTS) is actually the third generation mobile, which uses WCDMA. The Dream was that 2G and 2.5G systems are incompatible around the world.

To develop a single standard that would be accepted around the world.
-One device should be able to work anywhere.
Increased data rate.
- Maximum 2048Kbps
UMTS is developed by 3GPP (3 Generation Partnership Project) a joint venture of several organization
3G UMTS is a third-generation (3G): broadband, packet-based transmission of text, digitized voice, video, multimedia at data rates up to 2 Mbps
Also referred to as wideband code division multiple access(WCDMA)

The higher bandwidth also enables video conferencing or IPTV.
Once UMTS is fully available, computer and phone users can be constantly attached to the Internet wherever they travel and, as they roam, will have the same set of capabilities.
Network Layer design Issues.pptx
The network layer provides two main services: connectionless and connection-oriented. Connectionless service routes packets independently through routers using destination addresses and routing tables. Connection-oriented service establishes a virtual circuit between source and destination, routing all related traffic along the pre-determined path. The document also discusses store-and-forward packet switching, where packets are stored until fully received before being forwarded, and services provided to the transport layer like uniform addressing.
Classification of routing protocols
This document discusses different types of routing protocols for mobile ad hoc networks. It begins by classifying routing protocols into four categories: proactive (table-driven), reactive (on-demand), hybrid, and geographic location-assisted. It then provides more details on proactive protocols like DSDV, and reactive protocols like DSR and AODV. For DSDV, it describes how routing tables are regularly exchanged and updated when link breaks occur. For DSR and AODV, it explains how routes are discovered on-demand via route requests and replies. Key differences between DSR and AODV are also summarized.
Gsm call routing
This document provides an overview of call routing in GSM networks. It discusses key components like the Home Location Register (HLR) and Visitor Location Register (VLR) that store subscriber data. It then describes different call routing scenarios like mobile originated calls, mobile terminated calls, and roaming calls. It explains the signaling process and interactions between network elements like the mobile station, base station, MSC, HLR, and other switches. Finally, it briefly discusses the handover process to transfer calls between base stations when a mobile changes location.
Network Layer
This document provides an overview of various topics related to the network layer, including IPv4, IPv6, ARP, RARP, mobile IP, routing algorithms, and routing protocols. It begins with basics of IPv4 such as its addressing scheme and role in interconnecting networks. IPv6 is then introduced, along with reasons for its development and key features like its large 128-bit addresses. Address Resolution Protocol (ARP) and Reverse ARP (RARP) are also covered. The document concludes by discussing routing algorithms like link-state and distance-vector, as well as protocols including RIP, OSPF, and BGP.
Computer network switching
This document discusses different types of computer network switching, including circuit switching, packet switching, and virtual circuit switching. Circuit switching establishes a dedicated connection between nodes for the duration of a call. Packet switching divides messages into packets that are routed independently through a network on a first-come, first-served basis without dedicated connections. Virtual circuit switching combines aspects of circuit switching and packet switching by establishing paths for packets through a three-phase process of setup, data transfer using local addressing, and teardown.
Media Access Control
S.VIJAYALAKSHMI M.SC(CS) discusses Media Access Control and multiple access protocols. The main task of MAC protocols is to minimize collisions and utilize bandwidth by determining when nodes can access the shared channel, what to do when the channel is busy, and how to handle collisions. Early protocols like Aloha and slotted Aloha were inefficient at high loads due to many collisions. CSMA protocols reduce collisions by having nodes listen first before transmitting, but collisions are still possible due to propagation delays.
Location Aided Routing (LAR)
LAR utilizes location information to improve routing efficiency by reducing control overhead. It uses GPS to obtain geographical information. There are two zones in LAR - the ExpectedZone where the destination is expected to be, and the RequestZone which is the area where routing packets can propagate. PAR aims to minimize energy consumption per packet by calculating the sum of energy required at each hop. It also aims for maximum network connectivity and uniform distribution of power consumption across all nodes.

Finally, it categorizes common MAC protocols as fixed assignment, demand assignment, and random access and notes additional energy conservation requirements for wireless sensor networks.
Leach protocol
The document discusses the LEACH protocol and DECSA improvement for wireless sensor networks. It describes the two phases of LEACH - the set-up phase where cluster heads are chosen and the steady-state phase where data is transmitted. DECSA considers both distance and residual energy to select cluster heads, forming a three-level hierarchy. DECSA prolongs network lifetime by 31% and reduces energy consumption by 40% compared to the original LEACH protocol.

Mobile Adhoc Networks (MANETs) are peer-to-peer, multihop wireless networks where nodes are free to move and the network topology can change randomly. Routing in MANETs must be distributed and avoid broadcasts as much as possible due to limited resources and dynamic topologies. There are two main routing approaches - proactive protocols continuously evaluate routes while reactive protocols find routes on demand. Ad Hoc On-Demand Distance Vector (AODV) routing is a reactive protocol where a source node initiates a route discovery by broadcasting a route request to find destinations, and intermediate nodes reply with route replies to establish forward paths.

The document provides information about ad-hoc networks, including their characteristics, applications, design issues, and routing protocols. Some key points:
- Ad-hoc networks are infrastructure-less and use multi-hop wireless links between mobile nodes, requiring distributed routing protocols. They are suitable for situations requiring quick deployment like emergencies or military operations.
- Challenges for routing in ad-hoc networks include the dynamic topology, limited bandwidth and energy of nodes, and lack of a centralized entity. Traditional link-state and distance-vector routing protocols are examined.
- Popular link-state protocols like OSPF work by flooding link-state information to build a shared topology database and calculate the shortest path tree

The Effects of Speed on the Performance of Routing Protocols in Mobile Ad-hoc...Narendra Singh Yadav
Mobile ad hoc network is a collection of mobile nodes communicating through wireless channels without any existing network infrastructure or centralized administration. Because of the limited transmission range of wireless network interfaces, multiple "hops" may be needed to exchange data across the network. Consequently, many routing algorithms have come into existence to satisfy the needs of communications in such networks. Researchers have conducted many simulations comparing the performance of these routing protocols under various conditions and constraints. One question that arises is whether speed of nodes affects the relative performance of routing protocols being studied. This paper addresses the question by simulating two routing protocols AODV and DSDV. Protocols were simulated using the ns-2 and were compared in terms of packet delivery fraction, normalized routing load and average delay, while varying number of nodes, and speed.CS6003 AD HOC AND SENSOR NETWORKS
This document discusses routing protocols for ad hoc wireless networks. It begins by outlining some key issues in designing routing protocols for these networks, such as mobility, bandwidth constraints, and frequent topology changes. It then classifies routing protocols as being either table-driven, on-demand, or hybrid approaches. Table-driven protocols maintain consistent, up-to-date routing information through periodic table updates. On-demand protocols only discover routes when needed, to reduce overhead. The document proceeds to describe several examples of these different routing protocol types.

Performance Comparison of AODV and DSDV Routing Protocols for Ad-hoc Wireless...Narendra Singh Yadav
This document compares the performance of two routing protocols for mobile ad hoc networks: Destination Sequenced Distance Vector (DSDV) and Ad Hoc On-Demand Distance Vector (AODV). It presents the results of simulations run using the ns-2 network simulator. The simulations varied the number of nodes, pause time (mobility rate), and number of data sources. The performance metrics measured were packet delivery ratio, average end-to-end delay, and normalized routing load. The results showed that AODV had higher packet delivery ratios and lower routing loads than DSDV. However, AODV experienced higher delays than DSDV due to its on-demand route discovery process. DSDV performed better in lowPerformance Evaluation of DSDV & OLSR Proactive Protocols in MANET
MANETS are working in distributed environment and dynamically changing the network topology. MANET protocols can be table driven or on demand as per requirement. DSDV (Destination Sequenced Distance Vector) and OLSR (Optimized Link State Routing protocol) both are table driven (proactive) protocol. Performances of both proactive protocols are evaluated using NS-2 simulator under various metrics and no. of mobile nodes is 10 in the network.
J011137479
1) The document simulates and compares the performance of AODV and DSDV routing protocols in a mobile ad hoc network under three conditions: when users are fixed, when users move towards the base station, and when users move away from the base station.
2) The results show that both protocols have higher packet delivery and lower packet loss when users are either fixed or moving towards the base station, since signal strength is better in those scenarios. Performance degrades when users move away from the base station due to weaker signals.
3) AODV generally has better performance than DSDV, with higher throughput and packet delivery rates observed across the different user mobility conditions.

FM-Foster - Seeley Discriminator.pptx
This document discusses the Foster-Seeley phase discriminator, which is a type of frequency discriminator used in FM receivers. It operates by comparing the phase difference between primary and secondary voltages in a transformer tuned to the center frequency. When the input frequency matches the center frequency, the phase difference is 90 degrees and the output is zero. If the input frequency increases or decreases from center, the phase difference changes and a positive or negative output voltage is produced, making it useful for demodulating FM signals. The Foster-Seeley discriminator provides good linearity but requires a transformer and limiter before it.
Generation of DSB-SC using Diode Ring Modulator or chopper Modulator.pptx
This document discusses a ring modulator method for generating a double sideband suppressed carrier (DSB-SC) signal using amplitude modulation. It has advantages like a stable output and not requiring external power. The operation involves using diodes in a ring configuration to selectively pass or block the carrier signal depending on the polarity of the modulating signal. Coherent detection can then be used to recover the message signal from the DSB-SC by synchronizing the local carrier signal.
Generation of AM-DSB-SC using Balanced FET Modulator.pptx
This document discusses amplitude modulation using a balanced FET modulator. It begins by providing the mathematical representation of an AM-DSB-SC waveform. It then describes how a balanced FET modulator can be used to generate an AM-DSB-SC signal. Specifically, it explains that a balanced FET modulator uses two matched FETs in a differential amplifier configuration. The carrier signal is applied in phase to the gates, while the message signal is applied out of phase. This results in an output signal that is amplitude modulated by the message signal. The document concludes by noting that while a balanced FET modulator can heavily suppress the carrier, it cannot achieve 100% carrier suppression due to imperfect matching of the F

In the constantly evolving field of cybersecurity, ensuring robust protection for sensitive data and critical systems has never been more vital. As cyber threats grow more sophisticated, organizations continually seek innovative ways to bolster their defenses. One of the most effective tools in the security arsenal is Multi-Factor Authentication (MFA), particularly when integrated with Privileged Access Management (PAM).
Privileged Access Management encompasses the methods, procedures, and tools used to regulate and monitor access to privileged accounts within an organization. Users with privileged accounts possess elevated rights, enabling them to perform essential operations such as system configuration, access to sensitive data, and management of network infrastructure. However, these elevated privileges also pose a significant security risk if they fall into the wrong hands.
By combining MFA with PAM, organizations can significantly enhance their security posture. MFA adds an additional layer of verification, ensuring that even if privileged account credentials are compromised, unauthorized access can be thwarted. This integration of MFA and PAM provides a robust defense mechanism, protecting critical systems and sensitive data from increasingly sophisticated cyber threats.

Social media management system project report.pdf
The project "Social Media Platform in Object-Oriented Modeling" aims to design
and model a robust and scalable social media platform using object-oriented
modeling principles. In the age of digital communication, social media platforms
have become indispensable for connecting people, sharing content, and fostering
online communities. However, their complex nature requires meticulous planning
and organization.This project addresses the challenge of creating a feature-rich and
user-friendly social media platform by applying key object-oriented modeling
concepts. It entails the identification and definition of essential objects such as
"User," "Post," "Comment," and "Notification," each encapsulating specific
attributes and behaviors. Relationships between these objects, such as friendships,
content interactions, and notifications, are meticulously established.The project
emphasizes encapsulation to maintain data integrity, inheritance for shared behaviors
among objects, and polymorphism for flexible content handling. Use case diagrams
depict user interactions, while sequence diagrams showcase the flow of interactions
during critical scenarios. Class diagrams provide an overarching view of the system's
architecture, including classes, attributes, and methods .By undertaking this project,
we aim to create a modular, maintainable, and user-centric social media platform that
adheres to best practices in object-oriented modeling. Such a platform will offer users
a seamless and secure online social experience while facilitating future enhancements
and adaptability to changing user needs.

- 2. Content MANET ROUTING PROTOCOLs 1. Proactive – Destination-Sequenced Distance-Vector Routing (DSDV) or Table driven routing protocols 2. Reactive - Adhoc On demand Distance Vector Routing- (AODV)
- 3. Proactive – Destination-Sequenced Distance-Vector Routing (DSDV) • Each mobile nodes keeps a routing table. • Table driven routing protocols • Each of the routing table contains the list of all available destinations and the number of hops • Each table entry is tagged with a sequence number which is originated by the destination nodes. • Periodic transmissions of updates of the routing tables help maintaining the topology information of the network.
- 4. DSDV • If there is any new significant change for the routing information, the updates are transmitted immediately • Routing information updates might either be periodic or event driven. • DSDV requires each mobile nodes in the network to advertise its own routing table to its current neighbors. • The advertisements, is done either by broadcasting or by multicasting. • By the advertisements, the neighboring nodes can know about any change that has occurred in the network due to the movements of nodes.
- 5. DSDV (Contd.) • The routing updates can be in two ways: • Full dump: the entire routing table is sent to the neighbors • Incremental update: only the entries that require changes are sent. • Full dump: is transmitted relatively infrequent when no movement of node occur. • Incremental update: could be more appropriate when network is relatively stable, so that extra traffic could be avoided. • When the movements of nodes become frequent, the size of the incremental updates become large. • In such a case, full dump is useful.
- 6. DSDV (Contd.) • Sequence number is used to denote that an update is new or old • For updating the routing information in a node, the update packet with the highest sequence number is used. • Each node waits up to certain time interval to transmit the advertisement message to the neighbors, so that the latest information with better route to a destination can be informed to the neighbors.
