Abstract
This paper studies two key challenges in wireless multi-hop network: resource utility and network throughput. Our solution is a multi-constrained optimization scheme based on cross-layer design and its cooperative mechanism. The proposed scheme incorporates the energy threshold in physical layer and the channel capacity in link layer, and integrates the advantages of tight coupling and loose coupling. In addition, the bargaining game theory is applied to analyze the bargaining behavior of network nodes. The simulation results show that our optimization scheme can significantly improve the fairness and effectiveness of the network.
