Performance Analysis of Energy-Efficient MANETs-Using Modified AODV (M-AODV)

Mobile Ad hoc Networks (MANETs) have no centralized infrastructure; they are dynamic in nature. A node can act as a host or a router and can freely join or leave the network any time. The challenges in creating MANETs are mainly because of their limited physical security and energy constraints. As most of the nodes are battery operated their energy gets drained rapidly. This paper presents a modification of the existing AODV routing protocol called M-AODV. AODV uses the HELLO packets to discover and maintain the neighbors; we have added two new parameters in HELLO packet that is Trust and the Willingness (based on the remaining battery of the node). The intermediate nodes for routing packets are selected based on these two parameters. NS2 simulator is used for analyzing the performance of the protocol in terms of throughput, PDR, Packet drop, and routing overhead. All the performance parameters for the proposed algorithm were compared with the regular AODV and the results for M-AODV compared to AODV are better.
