EE-AODV: Energy Efficient AODV routing protocol by Optimizing route selection process

Statistics shows that wireless technology is gaining popularity day by day. Today, people sitting at either ends of the country can communicate with each other with the help of wireless technology. But energy efficiency is a critical issue for battery-powered mobile devices in ad hoc networks and routing based on energy relate parameters is used to extend the network lifetime. This paper proposes an EE-AODV routing protocol which is an enhancement in the existing AODV routing protocol. The routing algorithm which is adopted by Energy Efficient Ad Hoc Distance Vector protocol (EE-AODV) has enhanced the RREQ and RREP handling process to save the energy in mobile devices. EE-AODV considers some level of energy as the minimum energy which should be available in the node to be used as an intermediary node (or hop). When the energy of a node reaches to or below that level, the node should not be considered as an intermediary node, until and unless no alternative path is available. Simulation results show that lifetime of network increased in EE-AODV as compared to AODV
