In this paper, performance analysis of Location Aided Routing (LAR) protocolin different city scenarios has been done. The mobility model considered isManhattan model. This mobility model used to emulate the movement pattern ofnodes i.e., vehicles on streets defined by maps. Our objective is to provide aqualitative analysis of the LAR protocol in different city scenarios inVehicular Ad hoc Networks. We have considered three different city scenariosfor the analysis of the protocol. The simulation work has been conducted usingthe Glomosim 2.03 simulator. The results show that LAR1 protocol achievesmaximum packet delivery ratio is 99.68 % and maximum average end-to-end delayis 7.319969 ms when the network is sparsely populated. Further, for denselypopulated network maximum achieved packet delivery ratio is 87.58% and averageend-to-end delay is 0.017684 ms.
