| 摘 要： | 为了在链路质量不可靠的无线传感器网络(WSN)中提高数据传输的能效，提出一种基于模糊综合评判的WSN可靠转发协议FiaRD。FiaRD利用WSN节点部署稠密的特点和无线信道的广播特性，使传输路径上相互邻近的节点自发组织成多跳簇，进而通过各个簇成员间的协作转发来提高数据传输的可靠性和能效。每跳簇是通过分布式“模糊综合评判”与“回退竞争”相结合的机制动态选出的，此机制在对多个候选簇进行综合评判的基础上，能从中筛选出少数较优的来参与下一跳的竞争，从而降低簇间的碰撞概率，提高转发效率。仿真结果表明，FiaRD在保证可靠传输的同时，具有较低的传输能耗。

| Abstract: | A fuzzy integrated assessment based reliable forwarding protocol(FiaRD) was proposed to enhance the data transmission efficiency in Wireless Sensor Networks(WSN) featured by unreliable link quality.Utilizing characteristic of dense deployment of sensor nodes and broadcast feature of the wireless channel,FiaRD enabled multihop clusters to be self-organized by the neighboring nodes along transmission path and then leveraged the collaborative forwarding among cluster members to enhance the delivery ratio and e... |
