Cooperative MAC Protocol with Automatic Relay Selection in Distributed Wireless Networks
Chun‐Ting Chou, Jun Yang, Dong Wang · 2007
Cooperative transmission can obtain spatial diversity without using multiple antennas, thus achieving more reliable transmission or consuming less power. To realize cooperative communication in a distributed wireless network, two key questions need to be answered, namely when to cooperate and whom to cooperate with. In this paper, we propose a distributed MAC protocol with automatic relay selection to address these questions. We show by theoretical analysis and simulation results that the proposed solution outperforms conventional noncooperation transmission by 8 to 10 dB, for various target outage probabilities
