Device-to-Device communication in vehicular ad hoc networks and 5G networks

Abstract: With the capability of creating proximity gain and hop gain, direct device-to-device (D2D) communication technique has been considered as an effective solution to proximity-based services in the next generation cellular networks. In this talk, two typical scenarios adopting D2D communication technique will be discussed, i.e., Vehicular Ad Hoc Networks (VANETs) and content distribution.

VANETs are designated to provide vehicle-to-vehicle (V2V) communications by use of the D2D communication technique underlay cellular network. Since the vehicular communication environment shows more complicated characteristics compared with conventional cellular systems, efficient resource allocation strategies for D2D communications in VANETs are demanded.

Another typical scenario of D2D communication is the content distribution, where a number of information sources broadcast their messages to multiple destinations in the vicinity. In this scenario, a class of finite-field network codes which is adopted in the system to improve communication reliability and spectral efficiency will be introduced.
