摘要
近年来,随着基于802.11协议的无线网络的广泛的应用,提高网络的吞吐率,成为亟待解决的问题。现有的算法以提高空间重用为目的,调整载波侦听阈值和速率或发送功率和速率。这些算法在一定程度上提高了网络总的吞吐率,但也都存在一定的弊端。
In recent years,with the wide application of wireless network based on 802.11 Protocol,how to increase the network throughput becomes an urgent problem.The present algorithms aim to improve the spatial reuse by adjusting the carrier sensing threshold and rate or the transmission power and rate.These algorithms enhance the total throughput to a degree but also involve some drawbacks in the meanwhile.
