Heuristic Mobility-Aware OLSR Protocol for inter-vehicle communication (VANET)

Heuristic Mobility-Aware OLSR Protocol was designed for VANETs in which nodes rapidly changed in speed and direction. This protocol will be collecting information of adjacent nodes and interpreting as a routing cost. The sum of the routing cost of all nodes along a candidate route is to be a routing metric. The route with the minimum cost index is selected based on the key that the lower the routing cost the robust the route is. The routing metrics for measuring the routing cost is incorporated with the transmission capability, the reliability and congestion around the link including the data rate, queuing delay, link quality, and MAC overhead. Our simulation results proved that the proposed routing protocol attains the stable link and throughput.
