A Game-theoretic Approach for Cooperative Transmission Strategy in Wireless Networks
Cooperative Transmission (CT) is a promising technique to improve transmission rate and throughput in wireless networks, and Relay Node (RN) which could provide a good two hop channel plays a key role in CT mode. As a result, most of existing work take the advantage of benefit of RN in CT mode, but do not fully recognize its potential adverse effect. In this paper, the authors investigate the adverse impact called Flow-level Co-operation Interference (FCI) incurred by RN in CT mode, therefore, CT mode may not be beneficial as expected. To this end, they describe their insight and analyze the reason of FCI in wireless networks.
