A New Mobile Relay Selection Scheme in Vehicle Cooperative Communication Network

Existing works about relay selection in Vehicle Cooperative Communication (VCC) network assume that only relay nodes move around while source nodes and destination nodes are static. However, in the practical VCC network, source nodes and destination nodes are also mobile. To address this limitation, this paper considers the mobility of source and destination nodes, and designs a new mobile relay selection scheme, which targets at reducing system outage probability and increasing diversity gain and system capacity. In this paper, first, the authors utilize the Weibull fading channel model to analyze channel characteristics in the mobile environment. Secondly, a relay selection scheme is designed to improve the network performance. Finally, the performances of the mobile relay selection scheme by simulations were evaluated. Simulation results show that the selection scheme effectively reduces outage probability, and increases system capacity to achieve integrity of the well-organized system.
