Abstract

Vehicular Ad Hoc Networks (VANETs) arespecial type of Mobile Ad hoc NETworks (MANETs). It is an effective new technology to forward packets or sharing messages between vehicles (V2V) or vehicle to infrastructure (V2I). VANETs are considered as one of the most emerging technologies for enhancing the efficiency and the safety applications of transportation systems. The main use of VANET is to exchange traffic related information between the vehicles and prevention of accidents in transportation system. In VANETs vehicles move with the high mobility so it can be considered as the major concern. The challenge in VANETs applications is to send the Emergency Message (EM) to all the vehicles which are available in the communication range. But, because of the wireless communication medium, sharing of the packets and broadcasting of traffic information may lead to frequent altercation and collision, this problem called "broadcast overhead problem". In this paper, a QoS driven protocol is proposed to utilize the network bandwidth efficiently by reducing the broadcast overhead and forwarding the urgent or emergency messages first compared to other messages. This new protocol first finds the Minimum Connected Dominating Set of Vehicle (MCDSV) to reduce the broadcast overhead and the MCDSV acts as a virtual backbone for communication within the Network. After finding the MCDSV, we use the concept of a priority Queue for emergency broadcast scheme (VDEB) to resolve the issue of high overhead in senderoriented schemes and long delay in receiveroriented schemes. For the safety applications the broadcast protocol has to guarantee the performance and the reliability context. This combined method of Minimum Connected Dominating Set and Priority Queue demonstrate the good performances and the robustness of such protocol compared to other Routing protocols.
