中文摘要：

基于IEEE802.11协议的无线网络,受无线通信环境以及节点位置的影响较为明显。特别在节点较为密集的时候,MAC层的RTS/CTS机制将会严重的影响信号的空间复用度。通过研究影响数据正确接受的干扰范围与传输距离之间的关系,提出一种通过调节节点的传输功率,从而提高数据传输的空间复用度的算法。仿真的结果验证了这种算法能够明显提高网络的吞吐量。

英文摘要：

Wirdess communication environment and the nodes＇ localities have great influence on wireless network based on IEEE 802.11 protccol. Especially when the placement of the nodes is dense, RTS/CTS mechanism in MAC layer will break up the performance of signal＇s air diversity. In this paper, through the study of the relatiouship between interference range and transmission range, we propose a way of adjusting transmitting power to enhance air diversity. Simulation results verify that out scheme can effectivdy increase network＇s throughput.
