Executive Summary

In this paper, performance analysis of Location Aided Routing (LAR) protocol in different city scenarios has been done. The mobility model considered is manhattan model. This mobility model used to emulate the movement pattern of nodes i.e., vehicles on streets defined by maps. The authors' objective is to provide a qualitative analysis of the LAR protocol in different city scenarios in vehicular ad hoc networks. They have considered three different city scenarios for the analysis of the protocol. The simulation work has been conducted using the Glomosim 2.03 simulator. The results show that LAR1 protocol achieves maximum packet delivery ratio is 99.68 % and maximum average end-to-end delay is 7.319969 ms when the network is sparsely populated.
