A Stable Route Prediction and the Decision Taking at Sending a Data Packet in a Highway Environment

The critical challenge in vehicular ad hoc networks consists in designing a scheme that delivers a packet in a minimum period of time, reduces the frequent path disruptions caused by high mobility of vehicles and reduces the network overload caused by controls messages. Existing schemes suffer still from all these issues. For these reasons, this paper addresses these issues for non-safety applications in a highway environment. We propose a scheme that strives to predict a stable route by selecting the most stable neighbor relative to the transmitter of route request message, to minimize contention phase, to predict the route lifetime and the transmission time of the data packet for reduce of lost data packets and the route error messages. Our scheme increases the route lifetime duration, the percentage of packets delivery and reduces the control overhead.
