摘要
为研究拖拉机机载无线传感器网络的传输可靠性,针对遮挡障碍导致的信号衰落问题,提出了ZigBee机载无线传感器网络的传输可靠性评估模型。综合考虑无线通信模块故障率、数据处理模块故障率及两种衰落分布的链路质量,分别评估了平面和簇状结构下的可靠性。仿真测试结果表明,节点单链传输在4 m以内较为可靠,存在主导信号的莱斯分布可靠性更为明显,且簇状结构优于平面结构。
In order to study the transmission reliability of tractor wireless sensor network of agricultural machinery,a transmission reliability evaluation model of ZigBee tractor wireless sensor network was proposed to solve the problem of signal fading caused by occlusion obstacles.Considering the failure rate of wireless communication module,the failure rate of data processing module and the link quality under the two fading distributions,the reliability of flat structure and clustering structure was evaluated respectively.The simulation results show that the single⁃chain transmission of nodes is more reliable within 4 meters,and the rice distribution reliability with dominant signals is more obvious,and the clustering structure is better than the flat structure.
