Performance Analysis of Modified Power Level Based Dynamic Source Routing for MANETs

K. Palani, P. Ramamoorthy

Abstract


Ad hoc routing technology has been developed primarily for networks mobile nodes. The operational life of untethered nodes will be limited by its power source, so ad hoc networks strongly depend of the efficient use of their batteries. All the layers of communication and coupled in power consumption and solutions addressing the power saving issue include transmission power control, power aware routing and low power modes at the physical layer. At the network layer, routing protocols may balance power consumption at nodes according to the routing decisions. Several authors have proposed power aware routing algorithms based on power cost functions. In this work we present a performance analysis of Modified Power Level Based Dynamic Source Routing protocols for MANET was proposed in this study. The objective of this protocol is to reduce energy consumption in MANET while maintaining connectivity in the network. The overall result is that energy spent in transmitting overhead packets is reduced. This reduction allows more energy in transmitting data packets. The DSR protocol is modified to implement Modified Power Level Based DSR and these implementations are tested with a network simulator NS-2. The results of the simulation prove significant improvements of power consumption and controlling overhead packets.
