Performance Evaluation of FSR, LAR1 and ZRP Routing Protocols in MANET based on RWP Mobility Model

Mobile Ad Hoc Networks (MANETs) are self-configuring, infrastructure-less wireless ad hoc networks. It has a routable networking environment on top of the Link Layer ad hoc network. Routing is based on multi-hop pattern from source to a destination node/ nodes. Routing protocols for MANETs have to face the challenges of frequently & arbitrarily changing topology, low transmission power and asymmetric links. In this paper different routing protocols, namely FSR, LAR1 & ZRP, are comparatively discussed on the basis of Average End to end delay, Received Through-put and Average Jitter. An outline of these protocols has been presented in this paper by comparing their functionality, benefits, characteristics, limitations and analysis. RWP (random waypoint) mobility model has been used and simulations are performed using QualNet 6.1 version Simulator from Scalable Networks.
