RE-AODV an Enhancement of AODV Routing Protocol for Wireless Sensor Networks

Routing in Wireless Sensor Networks (WSNs) plays a significant role especially when mobility of nodes is introduced. Although, the introduction of the concept of mobility in WSNs has expanded their range of applications but it influences significantly the connectivity of the networks. In a mobile WSN, the topology of the network changes dynamically, roads maintained by some nodes become invalid, because of mobility of nodes. The main restriction of mobile WSN is the energy consumption. Thus, all routing protocols must consider this constraint and require an enhancement to consume less energy. In this paper we are working with Ad-hoc On Demand Distance vector (AODV) as a routing protocol, we are presenting an enhancement of this routing protocol based on residual energy of each node to optimize the energy consumption and maximize the network lifetime. We named the enhanced protocol: RE-AODV for Residual Energy-AODV.
