In this paper, we address the problem of greediness in IEEE 802.11 CSMA/CA protocol in Vehicular Ad-hoc Networks (VANETs). In VANETs some nodes might misbehave by deviating from following the CSMA/CA standard medium access protocol, in order to increase their channel access probability. Such behavior may have a catastrophic impact on the network performance as it causes denial of service for the other...
Multimedia streaming services in vehicular ad-hoc networks (VANETs) became a focus of many researchers. Achieving stable and high streaming rate under the high dynamic topology is considered a major challenge in such networks. Several approaches have been proposed to improve the existing routing protocols. However, some protocols ignore the QoS requirements needed for VANET safety and multimedia services...
In this paper, we address the problem of MultiPoint Relay (MPR) node disconnection due to mobility in Vehicular ad-hoc networks (VANETs) using the cluster-based Quality of Service Optimized Link State Routing (QoS-OLSR) protocol. The protocol uses MPR nodes to establish communication among the clusters. MPR disconnection represents a major challenge in VANETs, due to the frequent change in the network...
