Automatic Tuning Of OLSR Routing Protocol Using IWD in VANET

M.Gunasekar, S.J.Hinduja

Vehicular adhoc network (VANET) provides wireless communication among vehicles without any underlying Network Infrastructure. In such Network Quality-of-service (QoS) is difficult because the network topology may change constantly and the available state information for routing is inherently imprecise. However, due to the vehicle movement, limited wireless resources and the lossy characteristics of a wireless channel, providing a reliable multihop communication in VANETs is particularly challenging. Therefore, offering an efficient routing strategy is crucial to the deployment of VANETs. In this paper, we propose Intelligent Water Drops (IWD) algorithm to optimize the parameter setting in optimized link state routing protocol (OLSR). IWD Algorithm harmonizes the parameters in OLSR for better Qos. The QoS versions of the IWD tuned OLSR routing protocol do improve the Packet Delivery Ratio, reduce the communication cost and network traffic load in the high speed movement scenarios.
