Designing an Efficient Routing Protocol in MANETs

Power aware routing protocols are consistently cited as efficient solutions for ad hoc and sensor networks routing. However, there is not a consistent approach to define the energy related cost metrics that are used to guide the routing protocol performance. Nodes in a Mobile Ad hoc Network (MANET) have limited battery power. Power consumption of network interfaces can be significant. In a MANET, if a mobile node continuously transmitting the data packets, more battery power consumed by that node, obviously that node energy level is insufficient for data packet transmission and becomes critical node or dead node and result is connection failure in network. When a distance is increased between mobile nodes in same MANET, those mobile nodes consumed more power for the data packet transmission. The aim of this paper is to minimize the consumption power for operation so that transmission power can be saved. In this paper, we have considered three routing protocols such as Dynamic Source Routing (DSR) & Minimum Maximum Battery Cost Routing (MMBCR) and our proposed novel Power Efficient Routing (PER) protocol which increases the lifetime of the network by efficiently minimizing the power consumption. From the simulation results, it is observed that our proposed protocol gives improved network lifetime, packet delivery ratio and less end to end delay as compared to MMBCR and DSR protocols.
