In this paper, we have proposed a technique to detect and eliminate the malicious/misbehaving nodes involved during routing path formation in hierarchical mesh environments. In this, dijkstra's shortest path routing algorithm is used whose weights are deliberated using certain parameters (i.e....

Nowadays, rating systems play a crucial role in the attraction of customers to different services. However, as it is difficult to detect a fake rating, fraudulent users can potentially unfairly impact the rating's aggregated score. This fraudulent behavior can negatively affect customers and...

Wireless networks are used by everyone for their convenience for transferring packets from one node to another without having a static infrastructure. In WSN, there are some nodes which are light weight, small in size, having low computation overhead, and low cost known as sensor nodes. In...

These last years, an increasingly significant number of traffic accidents caused by a malaise at the steering wheel was observed. The management of this kind of phenomenon is difficult and presents a real challenge. Given this fact, the authors try, in this paper, to propose a work which, thanks...

VANETs are enhanced and upgraded versions of mobile ad-hoc networks which are fruitful for intercommunication vehicles. Communication can be vehicle-to-vehicle and between vehicles to side-fixed equipment known as roadside equipment. This network is self-organized, highly dynamic but separated...

This article proposes a slotted multichannel medium access control (SMMAC) protocol for VANETs to reduce CCH congestion, decrease RSU dependency, increase safety and data packet's reliability and improve fairness among vehicles. The main entity is the cluster head that not only notifies all the...
