Lifetime Maximization Energy Efficient Routing Protocol for Adhoc Wireless Networks

Ad hoc networks are wireless mobile networks that can operate without infrastructure and without centralized network management. Traditional techniques of routing are not well adapted. Indeed, their lack of reactivity with respect to the variability of network changes makes them difficult to use. Moreover, conserving energy is a critical concern in the design of routing protocols for ad hoc networks because most mobile nodes operate with limited battery capacity, and the energy depletion of a node affects not only the node itself but also the overall network lifetime. We propose an energy-efficient routing protocol, called improved ad hoc on-demand routing with lifetime maximization (IAODV-LM), which uses the RSSI based routing method to increase the network lifetime. Path selection mechanism uses receiver signal strength. This protocol improves the performance of ad hoc networks by prolonging the lifetime of the network. The protocol performance has been evaluated in terms of Throughput, Packet delivery ratio, and end-to-end delay.
