摘要:

无线Mesh网络可用信道和节点接口的缺乏限制了多播树链路的可用带宽,致使网络吞吐量下降。针对该问题,提出支持多播的多信道多接口信道分配算法——LAMCA。该算法能最小化无线Mesh网络的干扰程度,并最大化网络吞吐量。仿真结果表明,与层次信道分配算法LCA相比,该算法在吞吐量性能方面较优。

Abstract:

The scarcity of available channels and radios per node in the Wireless Mesh Network(WMN) limits the bandwidth available on the links of the multicast tree and eventually cuts the network throughput down. Aiming at this problem, this paper proposes a channel assignment algorithm for multicast in multi-channel multi-radio WMN called LAMCA. It can minimize the interference of multicast tree and improve the network throughput. Simulation results show that the algorithm can further optimize the throughput performance by comparing with the LCA algorithm.

Key words: channel assignment, multicast, multi-radio, Wireless Mesh Network(WMN)
