Abstract

In recent years, Vehicular ad hoc networks emerge as the promising applications of Mobile ad hoc network. It is specially designed for road safety and comforts to people. It assists vehicles to communicate among themselves and to perceive the road situation such as accidents or traffic jams in their vicinity. vehicular ad hoc network is the type of network which configures itself and can join or leave the network when they want. Due to this property of system, channel assignment is the major issue of the network. The channel assignment policy scheme is proposed in this research work is to improve the performance of the network. The channel assignment policy is based on data packets prioritization. The proposed scheme is implemented in NS2 and results are analyzed.
