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.

Abstract-Wireless

MANET is the hoc network with collection of wireless nodes that communicate to each other without any infrastructure, access point or centralized. In mobile ad hoc network, each nodes have own capability to forwarding packet and receiving each other device. In this Article, showing the performance of location aided routing protocol LAR based on the broadcasting data on nodes placement scenario using Random walk point RW. Broadcast packet on CBR that means constant bit rate transfer constantly on Random way point model with Pause time is zero and showing the effective performance of location aided routing protocol in mobile ad hoc network. The analysis of performance is based on different network metrics such as number of hops counts, number of routes selected, number of RREP received, number of RREQ discarded for loop, number of RREQ received, number of duplicate RREQ received, number of RREQ retired, number of data packet dropped for no route, number of RREQ forward, number of RREQ TTL expired and Residual Battery Capacity using simulation tools Qualnet 6.0.
