WLAN-Mesh网络多信道多速率接入协议的研究

On Multi-channel and Multi-rate WLAN-Mesh Network Access Protocol

在多个可用信道中,选出一个信道将它作为整个网络的公共控制信道,用来传输公共控制信息,其它的信道则继续担任数据信道的职责。而在每个信道上又依据接受信号的功率和噪声功率,通过函数计算发送数据的速率,以此来获得最佳传输速率。结果表明,这个协议有效地提高了网络平均吞吐量并降低了平均能耗以及端到端时延。

In a number of available channels,one channel was selected as a common control channel for the entire network to transfer the public control information and other channels will continue to serve as data channels.In each channel the rate of sent data was calculated through a function based on received signal power and noise power in order to obtain the best transferring rate.Results show that this agreement effectively raised the average network throughput and reduced the average energy consumption as well as end-to-end delay.
