A Stable Route and the Remaining Time Prediction to Send a Data Packet in Highway Environment

There are numerous research challenges to develop safety or non-safety applications in vehicular ad hoc networks (VANETs). One of the critical issues consists in designing a scheme that solves the local maximum problem, reduces contention phase, increases the route lifetime and reduces the frequent path disruptions caused by high mobility of vehicles. Existing schemes do not take into consideration all these issues. For this reason, this paper addresses these issues for non-safety applications in a highway environment. We propose a scheme that strives to find a stable route, minimize contention phase and predict the route lifetime and the average transmission time of the data packets. Our scheme increases the percentage of packets delivery, reduces the control overhead and decreases number of error messages generated during transmission of data packets as function of vehicles density.
