Although IEEE 802.11p technology is standardized for road safety and efficiency applications, the channel congestion problem is its key weakness necessitating distributed congestion control (DCC) algorithms on different layers of the communication stack. In this paper, we propose DCC-enabled Contention based Forwarding scheme targeting multi-hop dissemination of Decentralised Event Notification Messages...
A number of applications of Intelligent Transportation Systems (ITS) rely on multi-hop broadcasting in order to disseminate useful traffic information to other vehicles located in a geographical area. However, the conventional broadcast mechanism may lead to the so-called broadcast storm problem, which causes a high level of contention, collision, and congestion due to an excessive number of broadcast...
Many ITS (Intelligent Transportation Systems) applications require multi-hop forwarding of Decentralised Event Notification Message (DENM). If not well designed, multi-hop forwarding algorithms provide negative impact on the IEEE 802.11p vehicular systems, which already suffer from channel congestion caused by e.g., Cooperative Awareness Messages (CAM). In this paper, we propose an enhancement of...
