dc.description.abstractCooperative communications have been considered as a promising technique to deal with signal fading in wireless networks, and thereby increase the channel capacity. However, many practical issues remain to be addressed, especially in the medium access control (MAC) layer. In this thesis, we study two important issues toward the practice of cooperative wireless networks, i.e., energy saving and incentive design for cooperative MAC. First, we propose an energy-efficient cooperative scheme for the widely studied scenario with a single source-destination (S-D) pair. Extending the classic model to multiple S-D pairs, we further propose an effective and scalable cooperative scheme. Theoretical analysis is conducted for both schemes, and simulation results show that both schemes can achieve significant energy saving. In practice, due to the lack of incentives for wireless devices to serve as relays, cooperative communications are still not widely applied. Hence, in addition to energy saving, we also design an auction-based incentive mechanism to coordinate cooperative transmission between S-D pairs and relays. Both theoretical analysis and numerical results show that the proposed mechanism guarantees desirable properties.
