Abstract

An ad-hoc network is a network that comprised of mobilized devices communicating with each other through a centralized access network. Since nodes operate over a limited battery power and it is impractical to refill or replace the battery, hence it is important to design/modified an energy-efficient routing protocols for ad-hoc networks. Improving routing protocols to improve the lifetime of ad hoc networks have been an interested research area in the past few years. In this paper, number of simulations have been done in order to evaluate the quality of service for five routing protocols OLSR, AODV, LANMAR, DSR, ZRP under CBR traffic in terms of their throughput, mean end-to-end delay and jitter at the application layer in network scenarios. Various network scenarios are considered by varying number of nodes with mobility and non-mobility. The simulations are carried out in QualNet 6.1 simulator.
