ABSTRACT
This chapter discusses the novel vehicle clustering protocol that exploits the macroscopic social behavior of vehicles in order to create stable clusters for urban and high scenarios. The vision of the vehicular ad hoc network is very close to becoming reality and entering our everyday lives. Vehicles will be equipped with onboard units, that is, a communication device that allows short-ranged wireless transmissions and hence facilitates vehicle-to-vehicle communication. Node clustering is proven to be an effective method to provide better data aggregation and scalability for wireless ad hoc networks. In order to try to incorporate the social behavior of drivers in the clustering procedure, new parameters like rate of interactions among entities, historical data of driver behavior, and driver habits can be used. Road networks can be classified as complex networks, where the road segments and the junction connections do not follow regular patterns and may vary according to the geographical area.
