Improving AODV Protocol through Cross Layer Design in MANET

Mobile Ad hoc Networks (MANETs) are temporary formed, infrastructure-less networks. Performance metricsdegrades due to the unstable channel conditions, network connectivity, mobility and resource limitations. To improve different performance metrics, different cross-layering techniques are used where different layers from protocol stack communications with each other via exchange of information. AODV is a well reactive ad hoc routing protocol. In our work, we will focus 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. our research will also elaborates how the proposed model uses the received SINR to find its route. We will focus on parameters like response time, traffic throughput, packet loss, link stability, delay, optimal usage of battery resource to increase overall lifetime of a network.
