Study of Consequence on Traffic Density Patterns in the Performance of Routing Protocols for Vehicular Ad-Hoc Network

VANET (Vehicular Ad-Hoc Network) [1] which is a sub-sort of the MANET (mobile ad-hoc networks) gives wireless communication between the vehicle to vehicle (V2V), vehicle to infrastructure (V2I), and vehicles to the Road Side Units (RSU) [2]. In Vehicular Ad-Hoc Network, the correspondence between the vehicles is utilized for different purposes like security, solace, and amusement. n this paper, we've evaluated performance of varied routing protocols for VANET in several traffic patterns. The vehicular movements are supported intelligent driver model with road intersection. Our objective is to supply a comparative analysis among various unplanned routing protocols supported packet delivery ratio. Routing protocols are LAC, LAR1, AODV and DSR protocols. The traffic patterns categorize as sparse, moderate and dense based on the number of nodes. The results show that LAC Routing protocol outperforms others. The maximum packet delivery ratio obtained is 79.5% in the sparsely populated network. We have used Glomosim-2.03 [11], MobiSim [12], [13] and MATLAB [10] simulator for our analysis
