Efficient clustering based OLSR routing protocol for VANET

This paper proposed a Clustering approach based routing protocol for VANETs. The proposed algorithm is a distributed clustering algorithm together with OLSR Routing protocol, which possesses excellent Data dissemination rate, where Data dissemination is defined by throughput of protocol. In addition, the algorithm is also perform excellent in terms of End to End delay and exhibits a reasonable overhead. The algorithm is achieved by utilizing a new clustering technique based protocol called OLSR-C (OC). The clustering scheme uses a vehicle's position (provided by GPS) and velocity information to form clusters with low relative mobility between the cluster heads and their cluster members. The performance of the proposed algorithm is validated against the AODV, DYMO and OLSR routing protocol and outperform the routing protocol in term of End to End delay, throughput and PDR, thus provides a good benchmark for the algorithm's success.
