Reactive and Proactive Routing Protocol Energy Efficiency Performance Analysis in Wireless Ad

MANET (Mobile Ad hoc Network) is a self organizing and self configuring network without the need of any centralized base station. It is a collection of nodes that is connected through a wireless medium forming rapidly changing topologies. MANETs are infrastructure less and can be set up anytime, anywhere. In MANETs, the nodes are mobile and battery operated. As the nodes have limited battery resources and multi hop routes are used over a changing network environment due to node mobility, it requires energy efficient routing protocols to limit the power consumption, prolong the battery life and to improve the robustness of the system. This paper evaluates the performance of various ad hoc routing protocols such as DSDV, AODV, and DSR in terms of energy efficiency by varying pause time, node velocity and packet sending rate.. Simulation is done using NS-2(version NS-2.34). It has been verified through extensive simulations, which represent a wide spectrum of network conditions that AODV delivers the better performance as that of the state-ofthe-art algorithms DSDV and DSDV but it is observed that DSR needs significantly smaller energy expenditure than AODV and DSDV.
