6 - Opportunistic routing and delay-tolerant networking in vehicular communication systems

Abstract

Vehicular communication systems are characterized by their high degree of mobility and their dependence on traffic density. High velocity in sparse networks usually creates partitions that prevent the usage of traditional mobile ad hoc network protocols and algorithms. Nevertheless, vehicle mobility can be used to connect different sections of the vehicular ad hoc network. The delay-tolerant networking paradigm was specially designed for these kinds of networks: the ‘challenged networks’, that is, networks that do not satisfy the requirements of TCP/IP protocols to provide end-to-end connectivity.
