MANET consists of clusters of Mobile Nodes (MNs) on the access network that could be connected to other clusters through a fixed backbone of routers. The access link contention can severely constrain the end-to-end throughput of the path between a pair of source and destination MNs connected through the backbone. In this paper, we propose an integrated routing system for MANET that includes the backbone paths and the ad-hoc paths formed as a result of direct communication among MNs without going through the backbone. In our proposed routing system, an alternative ad-hoc path can be used only when the primary backbone path is severely constrained due to access links contention. We also propose a scheme for making the MN aware of link quality measures, and incorporate throughput metric in the core of AODV. We implemented the proposed routing syste...

This research focuses on one of the most important concepts in WSN technologies; the power conservation methods. The main objective of this research is improving the power conservation of a sensor node by dynamically adjusting recharging cycle of the solar-fed batteries based on the geographical areas and radiation levels of the areas and consequently prolonging the battery lifetime. The simulation results show that the proposed scheme improves the battery lifetime within the same geographical area from 0.69 year to 1.39 year; as well as across different areas from 0.69 year to 2.78 year.

Provisioning of QoS guarantees for a heterogeneous network is contingent upon the execution of an appropriate mapping among the QoS classes of the participating technologies. LTE and WiMAX are two flourishing technologies in the Fourth Generation (4G) and will remain so in 5G. Therefore, an adaptive QoS class mapping strategy is proposed for the incorporated LTE-WiMAX 5G Network. Simulation results revealed a satisfying performance in terms of QoS measures such as response time and Packet Loss Rate (PLR) for almost all types of traffic.

Dealing with management of such data is a challenge for DBMSs. According to several surveys, many company engineers choose Hadoop for their premier management system [5], due to its flexibility, ease of management and being open source software. However, more recently, database administrators of big company cite that Hadoop does not always work in their best interest in specific areas of data management. In order to solve big-data problems by providing considerable power of computability, Hadoop sacrifices efficient data processing. In the real-time data processing, Hadoop has lower speed than traditional DBMSs because it does not use high-level language, such as SQL and other query optimized languages. In this paper, we discuss methods to improve efficiency. Such improvements increase the ability of data processing in real-ti...

It has been proposed to complement with the existing wireless technologies such as cellular and WLAN networks. It is a powerful Broadband Wireless Access (BWA) technology, capable of providing many of the services and features promised by 4G wireless networks, such as multimedia services with high data rates and wide coverage area, as well as all-IP with security and Quality of Service (QoS) support. The IEEE 802.16 standard provides the preliminary specifications for Radio Resource Management (RRM) components and QoS requirements in different types and modes of operation.

Formerly, low-speed of 3G cellular networks made WiFi a dominant technology for high-speed data when present but today LTE plays the important role of obtaining data on cellphones even where WiFi is present. Additionally, the rewards available to attackers, within the hacking subculture have shifted from bragging rights to monetary rewards from organized criminal networks in exchange for information theft. On one hand, the vulnerability of always-on-cellphones, combined with the fast speed of LTE, highlights the role of security more than ever. On the other, there is a trade-off between security algorithms and speed. Hence there is significant need for security measures that balance security with the speed of data acquisition. In this paper we propose an algorithm that advances efficiency within that balance. We show in MATLAB how our new a...

In the current definition of their interfaces, the two 4G mobile broadband technologies (WiMAX and LTE) have introduced QoS mapping layers based on the dependency of the access technology. In this paper, a QoS framework is proposed to provide efficient and optimal traffic classification and end-to-end interoperability in a unified WiMAX-LTE network. We have simulated an integrated environment with WiMAX and LTE internetworking, and tested performance of the proposed framework by transmitting real-time (RT) and non-RT traffic, in isolated and mixed scenarios. Simulation results show that the proposed framework can provide end-to-end QoS support while satisfying the applications' traffic requirements.

Due to lack of centralized control, there is a large imbalance in the ratio of power consumption/power generation from one state to the next. This imbalance results in wasting of large quantities of power generated in states where generation exceeds consumption significantly, whereas other states are suffering from insufficient amount of power generation. Power generation is in direct correlation with the amount of resources used to generate the power. In this paper, we propose a power generation forecasting scheme that could predict the amount of power required at a rate closer to the power consumption. The proposed scheme uses Big Data analytics to process power management data collected in the past 20 years for each state. It then uses a Neural Network (NN) model to train the system for prediction of future power generation based on the collected data. Simulation shows that the proposed scheme can predict power generation close to 99% of the actual usage.

WiMax intended to be for metropolitan area network (MAN), designed to provide high speed downlink and uplink accesses to mobile users covering large radius over 50 miles for fixed stations and 3-10 miles for mobile stations. A single WiMAX station can operate and provide coverage for hundreds of users at a time and manage sending and receiving data at high speed with full network security; it is also designed to provide services in Line of Sight (LOS) and No Line of Sight (NLOS) modes for both point to point and point to multi-point users with the required Quality of Service (QoS) and security measures. Due to its low cost of network deployment (compare with 3G, HSDPA, xDSL, HFC or FTTh) it is now economically capable of growing to provide broadband Internet access in remote locations where either other services are too expensive to deploy or not reacha...

One of the main challenges in this area of research is how to tackle the problems of interference and resource allocation, especially for the hyper dense deployment of small cells. In this paper, we study the problem of cooperative interference mitigation in a small cell network. In particular, we develop a novel algorithm for encouraging small cell base stations to cooperate with their neighbors. Considering coalitional structure, small cells can mitigate the co-tier interference within a coalition and thus increase the system capacity. A cooperative approach among the adjacent small cells is formulated as a coalitional structure generation with characteristic forms. Meanwhile, during the coalition being formed, the associated frequency resources are also assigned. In contrast to the previous small cells' cooperative algorithms, a new feature for the proposed algorithm requires the computation for pairs of players. The proposed algorithm will raise the efficiency and is particularly applicable to the mass small cells' deployment scenario.

Nevertheless, WMN architecture has not received much needed attention compared to other topics in this area of research. Based on topological differences, various network architectures are possible for WMN, and we believe such architectures could affect wireless characteristics differently. In this article, we provide an overview of architectural design approaches for WMN, then summarize the state-of-the-art research findings and suggest further topics that need to be addressed. Additionally, we identify three different types of architectures for WMN: Campus Mesh (CM), Downtown Mesh (DTM), and Long Haul Mesh (LHM). Furthermore, we discuss and investigate different WMN characteristics that could be affected by commonly deployed architectures. Among the considered characteristics we select routing, network man...

A mapping among QoS classes of LTE and WiFi is performed first, then scheduling scheme is outlined. For scheduling scheme, traffic is separated into real-time (RT) and non-real-time (NRT) components, then a two-stage complex queuing strategy is performed. In the first stage, deficit weighted round robin queuing (DWRRQ) and class-based weighted fair queuing (CBWFQ) are used for RT and NRT applications respectively to segregate and forward traffic according to resource requirements. Whereas in the second stage, rate-control priority queuing (RCPQ) is used for all types of traffic to give each class appropriate priority level. Performance evaluation of the converged network was done based on different metrics such as jitter, end-to-end delay, throughput, and packet loss ratio. Simulation results show significant improvements for RT with slight degradation on NRT applications after using the new scheduling scheme.

However, Quality of Service (QoS) provisioning scheme is not fully defined for LTE, and it is left open for researchers to explore. In this paper, we propose a QoS provisioning technique for LTE. This technique involves a two-level scheduling scheme, consisting of a Rate-Controlled Priority Queuing Discipline (RCPQD) and a Deficit Weighted Round Robin Queuing Discipline (DWRRQD). To provision fairness, the scheduler considers the buffer content of the non-real-time applications, while priority is used to take differentiation of RT applications into account. The results show relative improvement in the performance of both real-time and non-real-time applications.
