Abstract

Broadcasting in vehicular networks is more prevalent than other transmission methods because of need to facilitate rapid, brief communications with nearby vehicles. However, the success of these message dissemination schemes relies on our ability to develop and implement routing protocols to specifically address the low latency requirements in a highly mobile environment. In this chapter we review broadcasting protocols that have been developed specifically for these networks. We also examine the primary factors affecting reliability of these protocols, namely transmission range, contention window size, and traffic configurations (shockwave disturbances and stop-and-go traffic).
