ABSTRACT

Mobile Ad hoc Network is an autonomous and decentralized network formed by wireless devices. Each device dynamically participates into the network and exits from it as they wish. Therefore establishing route in each situation is a difficult task. The big challenge in MANETs is to analyze the suitability of a routing protocol in various situations. The main aim of this paper is to analyze the performance of two well known routing protocols namely LAR and Fisheye state routing protocols in different placement environments. The experimental evaluation is performed using the Qualnet 7.0 simulator. The performance analysis is done in the QoS metrics mainly jitter, end-to- end delay, throughput and packet delivery ratio. The simulation result reveals that LAR protocol is better in random environment and fisheye state routing protocol is preferable in Grid environment.
