摘　　要：为了能够实时检测输油管道的运行状态,降低无线传感器网络(WSN)节点间的干扰,提高网络的吞吐量。提出了适用于节点链型分布的2种多信道WSN模型,讨论了单路径和双路径2种网络模型的信道分配方法和吞吐量,并且提出了相应的分布式MAC协议。根据机场输油管道的现场实验表明,单路径多信道WSN能够在降低能耗的情况下提高网络的吞吐量,双路径多信道WSN虽然需要较高的能耗,但具有一定的容错能力,而且网络吞吐量有很大提高。In order to detect the running state of oil pipeline in real time,reduce the interference between nodes of wireless sensor network（WSN） and improve network throughput,two multi-channel WSN models for the nodes distributed in a line were proposed;the models of channel assignment for single path and dual path network and their network throughputs were are discussed;the corresponding distributed MAC protocol was presented also.Field experiment results show that the single-path channel wireless sensor network not only reduces the energy consumption but also increases the network throughput;the dual path channel wireless sensor network has some fault tolerance and improves network throughput greatly,although it requires higher energy consumption.
