ABSTRACT In this paper, we discuss an interference aware multichannel MAC (IAMMAC) protocol assign channels for communication in wireless sensor-actor networks. An actor acts as a cluster head for k-hop sensors and computes the shortest path for all the sensors. Then, the actor partitions the cluster into multiple subtrees and assigns a noninterference channel to each subtree. The actor 1-hop sensors are represented as relay nodes. The actor selects a relay node as a backup cluster head (BCH) based on the residual energy and node degree. After selecting a BCH from the relay nodes, the actor broadcast this information to the remaining relay nodes using the common control channel. The relay sensors use the same channel of BCH to communicate with it. However, the other cluster members do not change their data channel. Further, interference-aware and throughput-aware multichannel MAC protocol is also proposed for actor–actor coordination. The performance of the proposed IAMMAC protocol is analyzed using standard network parameters such as packet delivery ratio, goodput, end-to-end delay, and energy dissipation in the network. The obtained simulation results indicate that the IAMMAC protocol has superior performance as compared with the existing MAC protocols

Internet of Vehicles (IoV) aims to make transportation easy for the user by trying to make the roads safer and more secure. The main challenge of IoV is that the vehicles should detect the pedestrians coming in their way spontaneously and immediately respond to this unexpected interference with minimum delay. So an intelligent transportation system named FOOTREST (saFety On rOads ThRough intElligent tranSporTation system) has been proposed to resolve this issue. FOOTREST identifies the approaching pedestrian quickly and then warns the other nearby vehicles and entities. It can be used for emergency conditions, detection of animals, specially abled person peoples and children’s also. The sudden arrival of pedestrian causes interference among vehicles and therefore the vehicles have to reconnect again in less time to reduce probability of any mishap.

The growing concern for the increasing number of road accident deaths draws our attention towards a replacement of the traditional traffic management system. In today’s scenario, Traffic collision is the eighth leading cause of deaths and injuries in all over the world, hence the ITS comes into the picture. Sensors mounted at strategic places can use IoT which is an ecosystem of smart devices that use embedded systems to collect, send and act on data they acquire from their environments. For the communication between vehicles and infrastructure we use V2I which is a communication framework that enables several vehicles to share information with a variety of devices. The scope of this project is divided majorly into two modules, namely DSTC and APAS. Together, these two modules serve the purpose of traffic congestion control and quick post accident care, which broadly help us to achieve the goal of Smart Traffic Management.

In this paper, a survey on routing protocols, challenges and applications in wireless mesh networks (WMNs) is conducted. Wireless Mesh network is a type of distributed, self-organizing, self-configuring and self-healing network. When access points in Wireless ...
