Abstract:
Ad-hoc On Demand Distance Vector (AODV) routing protocol has been one of the prominent routing protocols for Mobile Ad hoc Networks. AODV uses the hop count as a path selection metric. However, routing based on the hop count may not lead to optimal route selection. In this paper we propose a cross layered based routing protocol called Turbo-AODV (TAODV) where we modify AODV to calculate the weight of a certain route based on three factors, and then choose the route with the best weight. The three factors that make the base of route selection are: the received signal strength, the remaining energy and the remaining queue length. The route selection based on the following criteria ensures choosing the most stable route which has the less congested links. Performance evaluation through simulations showed that the proposed protocol performs better than AODV protocol in terms of packet delivery, normalized routing load, discarded packets on queues, and routing overhead.
