中文摘要：
网关是整个无线Mesh网络中数据流量汇聚的中心,网关周围的链路干扰将会制约整个网络的上下行吞吐量,然而在目前已有的信道分配方案中在进行信道分配时并未充分考虑到这一特点。提出一种以网关为中心的逐层多信道分配策略,在分配信道时尽可能优先考虑降低网关附件的冲突和干扰,从而达到提高整个网络性能的目标。仿真实验表明,本文算法在提高网络吞吐量方面达到了很好的效果。
英文摘要：
Gateway is the traffic aggregate point of the whole network,around which the interference will reduce both the uplink and downlink throughput.However,the existing channel assignment algorithms assign channels for node interfaces without considering the specific position of gateway.In order to decrease the interference and confliction around gateway,a multi-channel assignment algorithm based on the gateway position is proposed,the efficiency of which is proved by the simulation results.
