Routing protocols in V2V communication

In recent years, vehicle-to-vehicle (V2V) communications have been studied to improve driver safety. As more of such applications of high-mobility ad hoc networks emerge, it is critical that the routing protocol employed is capable of efficiently coping with the high frequency of broken links (i.e., robust with respect to high mobility). This chapter introduces a comprehensive and comparative study in a city environment of representative routing protocols developed for intervehicular networks and wireless mobile ad hoc networks. In a city environment, communication protocols need to adapt fast-moving nodes (e.g., vehicles on streets) and large obstacles (e.g., office buildings). In this chapter, the strengths and weaknesses of these techniques are discussed based on various network scenarios with regard to their support for highly mobile nodes.
