ABSTRACT
A vehicular ad hoc network (VANET) is a special kind of mobile ad hoc networks (MANET) that supports cooperative driving among communicating cars on the roads. There are several technologies involved in implementation of wireless communication in VANETs. These technologies include 3G cellular systems, long-term evolution (LTE), LTE Advanced, IEEE 802.16, and IEEE 802.11. This chapter focuses on 802.11-based wireless communication in VANETs. It reviews some presented methods for vehicle movement path prediction, and explains some algorithms are explained for performance improvement in opportunistic networks based on the predicted vehicle movements. The chapter considers the fact that communication in VANETs can be infrastructure-based or infrastructureless. It also reviews some methods to apply the predicted vehicles' position for improving communication in infrastructure-based and infrastructureless VANETs, respectively. Opportunistic routing algorithms can be classified according to their dependency on roadside infrastructure. The chapter presents the taxonomy of opportunistic routing in VANETs.
