Abstract

The optimized link state protocol (OLSR) is a table driven protocol, practical routing protocol is initially developed for mobile ad-hoc networks (MANETs).Vehicular ad-hoc network (VANET) is sub class of the MANET that consists of vehicle to vehicle communication and vehicle to roadside communication. The OLSR is used for the VANET but the standard configurations are not sufficient for the VANETs due to limited coverage of Wifi and the high mobility of the nodes generate frequent topology changes and network fragmentations so there is need of modified OLSR .Modified OLSR can be obtained by the optimization so optimum parameters to tune OLSR by aggregating the response performance metrics generated in a realistic VANETs simulation. The results show that OLSR having optimum parameters help to achieve better performance in urban environment as compared to the ordinary OLSR.
