Energy Efficient Consumption based Performance of AODV, DSR and ZRP Routing Protocol in MANET

This Mobile Ad Hoc Networks (MANET) is gaining importance because of their flexibility, mobility and ability to work with a limited infrastructure. In multi-hop wireless network, proper utilization of battery power is very much necessary to maintain network connectivity.In order to overcome the network from inefficient routing problem, this paper presents different energy efficient routing protocols like AODV, DSR and ZRP for mobile ad hoc networks. In this research, efforts is on methods to reduce the power consumption in communications between Ad hoc network nodes. The energy consumption is the critical issue in MANET that's why proposed the compared performance based analysis of three routing protocols i.e. AODV, DSR and ZRP. The different node density scenarios, different velocity scenarios and random velocity scenarious are presented in this research. The energy drain rate and energy cost per packet is also evaluated to scrutinize the performance of these routing protocols. The performance is analyzed by three metrics like PDR, Routing load and Throughput. All the three routing protocols are explained in a deep way with metrics. The different scenarios in different pause time, different mobility, random mobility and different node density are considered. The routing protocols AODV, DSR and ZRP simulation is done through NS-2 simulator. This research analyses that DSR routing protocol is the energy efficient routing protocol in MANET.
