A New Method to Enhance the Efficiency of peer-to-peer Vehicular Nteworks

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, estimationof the stability time of the route, before changing the route, causes a node to be informed and then compensates the lostconnection. In this paper, we establish a sustainable path between the two vehicles and largely reduced the network overhead. Sothat, first, a clustering structure to dividing the nodes will be used which effects on the efficiency. In the second stage beforeending the connection between the two vehicles, the alternativeroutes were studied and considered to be stable to replace new route. Finally, the results show that the proposed method thatuses clustering and considering stability time between two vehicles can reduce the delay of requesting the packet by thedesired to an acceptable level. The experimental results show that, the proposed method improves the rate and number of sentpackets, time and also the number of dropped packets, compared ASAP protocol.
