Gourab Bhattacharya . Performance Evaluation of AODV by Imposing Energy and Load based Approach of Path Selection. International Journal of Computer Applications. 177, 29 ( Jan 2020), 6-10. DOI=10.5120/ijca2020919755
A wireless Mobile Adhoc Network (MANET) is an infrastructure-less mobile network which is based on radio to radio multi-hoping and they have no centralized controller or a fixed router. In MANET all nodes are capable of movement and can be connected dynamically in an arbitrary manner. Due to the dynamic nature of network topology, frequent mobility, limited battery power, routing in MANETs is a challenging task. In addition to that, overloaded nodes may deplete their energy in forwarding others packets resulting in unstable network and performance degradation. The classical AODV routing protocol does not consider nodes energy or load while path selection procedure which declines its performance sharply in high load and fast moving velocity. This paper evaluates performance of AODV protocol when path selection is made considering the load and residual energy of the node. In this approach the nodes with low energy and high load is avoided by varying the delay time of broadcasting the RREQ packet. According to the simulation results using NS-2.35 the load and residual energy based path selection approach increases the stability & energy efficiency of the network significantly. Results show a non linear improvement of tthe network lifetime, packet delivery fraction, reduces the network routing load and number of dropped packets
