A new method to enhance the efficiency of peer-to-peer vehicular networks

Forecasting the next route of vehicles in Vehicular Ad-hoc Networks (VANET) that are based on routing pattern is useful to estimate the stability time of the route. Also, estimation of the stability time of the route, before changing the route, causes a node to be informed and then compensates the lost connection. In this paper, we establish a sustainable path between the two vehicles and largely reduced the network overhead. So that, first, a clustering structure to dividing the nodes will be used which effects on the efficiency. In the second stage before ending the connection between the two vehicles, the alternative routes were studied and considered to be stable to replace new route. Finally, the results show that the proposed method that uses clustering and considering stability time between two vehicles can reduce the delay of requesting the packet by the desired to an acceptable level. The experimental results show that, the proposed method improves the rate and number of sent packets, time and also the number of dropped packets, compared ASAP protocol.
