Optimized AODV using cross-layer optimization technique for mobile ad-hoc network

Mobile Ad-hoc network is wireless ad-hoc network which is infrastructure-less network which is decentralized in nature. It is difficult to make the technology to work effectively for the networks where there is no fixed infrastructure. A strong protocol is needed for making such networks to work efficiently and to remove the problems regarding to the routing. AODV is a popular on demand distance vector routing algorithm for the Ad-hoc networks. But still it is necessary to improve the performance of existing protocols for better performance and if we use the cross layer optimization techniques in the existing algorithms then it can give better performance. In this paper we have proposed modified AODV routing protocol which uses the physical layer information for the purpose of routing. The proposed modified AODV protocol gives better performance than the existing AODV routing protocol. The results of the simulations show improvement on performance metrics like end to end delay of existing AODV. Key wordsMANET, AODV, cross-layer
