Abstract:

Vehicular ad hoc networks (VANETs) are a special form of wireless networks made by vehicles communicating among themselves on roads. The conventional routing protocols proposed for mobile ad hoc networks (MANETs) work poorly in VANETs. As communication links break more frequently in VANETs than in MANETs, the routing reliability of such highly dynamic networks needs to be paid special attention.. In existing methods the vehicular mobility pattern and the vehicular traffic distribution are examples of factors that affect the reliable routing process. EG-AODV causes large delays in a route discovery, also route failure may require a new route discovery which produces additional delays that decrease the data transmission rate and increase the network overhead. We propose an Infrastructure Based Routing scheme consists of an Assisted Adaptive Data Dissemination protocol for vehicular networks. It uses static nodes at junctions to forward a packet and the data is forwarded through the best delivery path, which reduces the overall data delivery delay.
