| 摘 要： | 为合理地分配和利用无线信道资源,研究者们提出了许多关于多射频多信道无线Mesh网络的信道分配算法。该文针对无线Mesh网络的信道分配算法,以连接低干扰信道分配算法(CLICA)为基础,以提高网络容量(吞吐量)为目标提出了一种改进算法。该算法根据网络中各链路的干扰度来计算网络干扰度,通过减小网络的干扰度来提高网络吞吐量,以实现最小化网络干扰度的目标。构建信道分配的数学优化模型,通过NS2仿真验证比较改进前后算法的性能,求解出最优的信道分配。

| Abstract: | In order to rationally assign and utilize wireless channel resources, various multi-radio and multi-channel channel assignment algorithms for wireless Mesh network have been proposed. In this paper, an improved algorithm based on connected low interference channel assignment (CLICA) is presented to improve network capacity (throughput). The interference measure of each unit in the network is calculated based on the level of interference of each link in the network. The throughput of the network is improved by reducing the network interference level. The optimal channel assignment can be achieved by using mathematical optimization model of the channel assignment. |
