An autonomous relay access scheme for inter-vehicle communication network

This paper proposes an autonomous relay access algorithm that provides an intelligent wireless network structure for an inter-vehicle communication system. The proposed algorithm introduces a special classification among mobile terminals and assigns terminals to one of several terminal groups, which are adaptively and autonomously constructed according to traffic conditions. The proposed algorithm uses the terminal groups to conduct relay access transmission among terminals, and achieves a higher rate of successful inter-terminal transmission. Computer simulation confirms that the proposed algorithm can achieve a lower blocking probability than an algorithm without a relay access scheme
