An on demand routing protocol AODV with end to end reliability and backward route information

AODV protocol is a comparatively more popular on demand routing protocol in mobile ad hoc networks. However, reliability in terms of data communication is not much satisfactory in traditional AODV. This paper presents an AODV with end to end reliability (AODV-EER). The main idea of proposed modification in AODV is to find the route with lowest drop rate from source to destination. We also propose a backward route entry mechanism in order to initiate repair action after primary route breaks. We analyze the performance of proposed protocol on NS2 in terms of packet delivery ratio, normalized routing load, and end to end delay. The experiments clearly indicate that proposed protocol performs better than the traditional protocol AODV.
