Mobile Ad hoc Networks (MANETs) are temporary formed, infrastructure-less networks.The performance metrics deteriorate due to the unstable channel conditions, network connectivity, mobility and resource limitations.To improve different performance metrics, various cross-layering approaches are utilized where different OSI layer information are exchanged.AODV is a popular distance vector proactive routing algorithm.In our research we investigate a modified version of AODV routing protocol, based on route discovery by utilizing Physical Layer information instead of the minimum hop count approach of the default distance vector algorithm.The research also elaborates how the proposed model uses the received SNR to find its route.The paper also proposes future research direction for utilizing Polar Coding for fading channel.The results of the simulations show improvement on the existing default AODV performance metrics like MANET traffic throughput, application specific response time, data dropped, delay etc.
