Abstract: The routing protocols are playing very important job in the performance of both IP (Internet Protocol - Infrastructure based) and the mobile Ad-hoc networks (MANET). The Ad hoc On Demand Distance Vector (AODV) Routing Protocol is a reactive-table driven routing protocol for mobile ad hoc networks. The route discovery and maintenance process is based on the balanced energy level in the neighbouring pair of nodes. This research is a modification on the original AODV, a basic routing protocol for its enhancement. This is an attempt to use communication reliability factor prior to establish communication using energy levels. This is examined by simulation study experimented using NS-2 on Ubantu. The performance metrics used for comparison between AODV and new protocol are PDR, routing overhead, energy level and delay.
