| 摘 要： | 多信道多接口可以明显提高Mesh网络的吞吐量，然而已有的多信道分配算法和协议基本上都没有考虑无线信道的隔离度，这样便造成了路径间干扰。提出了一种基于信道隔离度的启发式多信道分配算法（CSCA），有效地减少了路径间干扰。所构建的森林拓扑一方面方便了信道分配，另一方面也改善了流量均衡。模拟实验结果表明，CSCA算法有效地降低了Mesh网络中的干扰，提高了网络吞吐量。 |

| Abstract: | Mesh network throughput can be reaped by multi-channel and multi-interface,however,the channel separation which can greatly reduce interference of inter-paths is almost not considered in existing multi-channel assignment algorithms and protocols,as a result,the mesh network throughput is still improved by reduction of the interference of inter-channels and inter-paths.A heuristic Channel Separation based Channel Assignmen（tCSCA） algorithm is proposed to combat the mesh wireless interference.The mesh forest topology discovered and constructed in this work facilitates the channel assignment and traffic flow balance.Extensive simulation shows that the CSCA efficiently combat interference of mesh network and indeed upgrades the mesh network throughput. |
| Keywords: | Mesh network channel assignment channel separation wireless interference |
