中文摘要：

主要致力于在多Radio多信道的无线Mesh网络中进行信道分配。在多Radio多信道无线Mesh网中进行信道分配是一个NP难问题，为了适应网络中链路的动态需求，提出了一种基于链路优先权的在线启发式信道分配算法（LDCA），在最小化网络冲突的前提下能最大化网络吞吐量。模拟实验结果表明所提出的LDCA算法与静态信道分配算法（SCA）和动态信道分配算法（DcA）相比，能够进一步减少传输时延，降低网络冲突，增加网络吞吐量。

英文摘要：

This paper addresses the problem of improving the network throughput in multi-radio multi- channel wireless mesh networks. Because channel assignment in multi-radio multi-channel wireless mesh networks is a hard problem in NP, in order to adapt to the dynamic demand of the link, propose a link weight priority based online heuristic channel allocation algorithm （LDCA）, the network conflict and mini- mize network throughput were minimized. Simulation experiment shows that the LDCA algorithm pro- posed in this paper can further reduce the network delay and the network interference while increase the network throughput when compared with both static channel assignment （SCA） and dynamic channel assignment （DCA）.
