摘　　要：线性传感器网络(LSN,linear sensor network)中的传感器节点因监测区域的线性拓扑而呈线性部署。目前用于LSN的基于占空比和流水线调度(DCPF,duty-cycling and pipelined-forwarding)的介质访问控制(MAC,medium access control)协议虽然能缩减数据包的传播时延并降低网络能耗,但还存在数据包传输时的竞争、干扰以及能量空洞问题。为此,针对LSN提出基于多信道和冗余节点部署的改进型DCPF协议。基于OPNET的仿真结果表明,相较于现有协议,所提协议在能量使用效率、包到达率、吞吐率、包传输时延等方面具有更好的表现。Sensor nodes in linear sensor network(LSN)are deployed linearly due to the linear topology of the monitoring area.Most of the state-of-the-art medium access control(MAC)protocols designed for LSN adopted the duty-cycling and pipelined-forwarding(DCPF)schemes.They can reduce data propagation delay and network energy consumption but may still cause issues such as transmission competition,interference,and energy hole.To address these issues,an improved DCPF MAC protocol was proposed based on multiple channels and redundant-node deployment for LSN.The extensive simulations based on OPNET demonstrate that,compared with existing protocols,the proposed protocol shows a better performance in terms of energy efficiency,packet delivery ratio,throughput,and packet transmission latency.
