Abstract

The traditional route selection algorithm of the Ad Hoc network are mainly based on the shortest path and do not take into account any other routing factors. As a result, it increases the number of the unreliable route. It also forms a lot of “hot spot”, which affect the performance of the network. Thus this paper proposes a performance value adaptive routing for mobile ad hoc network (PVAR), which is mainly based on the performance value of the route. The PVAR uses a cross-layer design method that involves the medium access control layer and the network layer, and introduces a new route selection algorithm. Simulation results show that the PVAR can perform much better than the DSR in route reliability improving, congestion controlling and load balancing.
