| 摘 要： | 由于移动ad hoc网络（MANET）终端能量的限制，延长终端节点的生存时间、高效地利用有限的网络资源成为MANET面临的重要挑战，因而传输功率控制起着及其重要的作用。提出基于θ的传输功率控制机制（θ－TPC），在单信道单收发机的环境下，根据通信对的距离动态调整传输功率，并改变参数θ使其能量效率和吞吐量同时达到最佳。最后根据仿真证明θ－TPC机制相较于IEEE802.11能量效率和吞吐量都有很大提高。

| Abstract: | Due to the energy limitation of terminals in mobile ad hoc network（MANET），transmission power control plays an important role in extending the lifetime of terminal nodes，efficiently utilizing limited network resource.In this paper，transmission power control mechanism（θ－TPC） is proposed，in the environment of single channel and single transmitter-receiver，dynamically adjust transmission power according to the distances of traffic pairs，and alter parameter θ to achieve optimal energy efficiency and throughput.Finally，simulation experiments demonstrate θ－TPC mechanism get a great improvement on energy efficiency and throughput compared to IEEE802.11. |
