Abstract :
Vehicular communication technologies are realized recently as the staples of modern societies. When cooperative approach is employed in vehicular communication system, it will perform more effective in avoiding accidents and traffic congestions. In vehicular networks, cooperative Multi-Input Multi-Output (MIMO) and cooperative relay techniques increase the performance as well as reduce the transmission energy consumption by exploiting the spatial and temporal diversity gain. The energy efficiency characteristics of cooperative techniques in vehicular networks is of prime importance as the energy consumption of wireless nodes embedded on road infrastructure is constrained. In this paper, applications of cooperative communication techniques in vehicular networks are proposed. Also we compare the performance and the energy consumption of cooperative techniques with the traditional multi-hop technique over Rayleigh channel by considering MQAM as design example. The optimal cooperative strategy for energy constrained road infrastructure networks in ITS application can be selected using this performance optimization in cooperative communication.
