GOSSIP BASED NODE RESIDUAL ENERGY AODV ROUTING PROTOCOL FOR AD-HOC NETWORK (GBNRE-AODV)

Abstract

In traditional/classical routing approach, any newly RREQ packet received at a node is retransmitted with probability of one regardless of node density, received signal power and node’s energy level. In MANETs, the network topology is dynamic and the level of residual energy of each node varies over time. Therefore, the forwarding probability used in probabilistic broadcast schemes for the dissemination of broadcast packets should be set dynamically to reflect the local and global information about the network (i.e. neighborhood information, received signal power and the residual energy of a route).In this paper, we have designed a novel energy aware routing protocols called Gossip based Node residual energy AODV (GBNRE-AODV) which uses residual energy, hop count, node received signal power and node density as a cost metric to reduce energy consumption, increase network lifetime and distribute usage of energy among mobile nodes of Mobile Ad hoc Network (MANET). The new protocols, which are referred to GBNRE-AODV are simulated using Network Simulator-2.34 and comparisons are made to analyze its performance based on network lifetime, normalized energy consumption, delivery ratio, normalized routing overhead, average collision rate, and average end to end delay for different network scenarios. The simulation results reveal that the proposed energy aware routing protocols make the network active for longer interval of time by minimizing energy and distributing energy consumption across mobile nodes on the network at the trade off a small amount of end to end delay.
