摘要： 针对多跳稠密的移动Ad hoc网络面临的网络生存时间、无线资源利用效率以及时延要求等问题，提出一种新的功率控制MAC协议，该协议在功率退避基础上结合改进的时间退避机制，采用较灵活的竞争窗口调节方法有效地缓解冲突。仿真结果表明，该协议可以减少移动节点消耗的功率，提高节点的能量利用效率和系统的吞吐量性能。

Abstract: A novel power control Medium Access Control(MAC) protocol for multi-hop dense Mobile Ad hoc Networks(MANETs) is proposed to realize high energy efficiency and improve network throughput. The basic idea of the proposed protocol is that, using the more flexible contention window adjustment method to resolve collisions efficiently. Simulation results show that the proposed protocol is efficient and can improve network throughput in most scenarios.
