Abstract: Cooperation communication is a hot research topic in wireless communication presently. hhe first problem to be solved is how to select the cooperative relay in cooperation communication. We Proposed a criterion to evaluate the technology of cooperative relay selection. Then we classified, analyzed and compared these algorithms that proposed in recent years. At last, we look forward to the developed direction of the algorithm of cooperative relay selection.

Key words: Cooperative communication, Relay selection, Wireless communication, Relay scheme
