Geographic Routing on Vehicular Ad hoc Networks

Abstract

This chapter introduces geographic routing in vehicular ad hoc networks (VANETs). The aim of this chapter is to clarify the basic principle of geographic VANET routing protocols by stating their ideas. To this goal, we explain the common ideas behind the geographic routing protocols, and consider issues in applying those ideas to vehicular ad hoc networks. Then we summarize a wide variety of protocols; from ones in early design stages to understand the basic principle, to state-of-the-art ones to know recent research trends. After that, we give the detailed design of an example protocol to understand the design principle of VANET geographic routing protocols. Finally, we summarize the protocols introduced in this chapter and discuss future directions for possible research issues.
