Abstract Vehicular ad hoc networks (VANETs) provide applications that focus on driver safety, traffic efficiency of vehicles on public roads, and the comfort and entertainment of passengers throughout their journey. Some of these applications require connections to the Internet via an access point (AP) at roadsides, such as a cell tower or Wi-Fi tower. A connection can generate an overhead of control messages and could suffer a change of AP that would impact application performance. Besides the interface connected to APs, vehicles are equipped with other network interfaces linked to various different technologies. Thus, a vehicular application can take advantage of the simultaneous use of these various network interfaces, thereby maximizing throughput and reducing latency. However, these additional interfaces can also serve as a connection to the APs located at roadsides. These multiple connections further increase the overhead of control messages and the time of change from one AP to another, thereby affecting the network throughput and, consequently, application performance. This chapter describes techniques and architectures that manage the communication among APs and vehicles to allow heterogeneous communications among several network technologies, such as wireless networks and cellular technology, reducing the impact of communication overhead on networks.
