摘　　要：针对传统随机部署无线传感器网络(WSNs)信号传输算法中能耗分布不均、影响网络使用寿命的问题,提出一种多环形泊松指数负载均衡分布WSNs信号传输机制。首先,利用sink节点发送"HELLO"数据包方式,构建多环形数据传输的分区机制;其次,为避免"HELLO"数据包产生冲突,给出数据包发送等待时间形式,同时,通过数值理论分析和图形化分析方式,给出多环节点能耗泊松指数分布形式。通过在网络模拟器NS-2上的仿真测试显示,该算法比采用两种对比算法具有更均匀的能耗分布及更长的网络使用寿命。In order to solve the uneven distribution of energy consumption in the traditional random deployment wireless sensor network（ WSNs） signal transmission algorithm,which influenced the network lifetime,this paper proposed multi ring Poisson index load distribution for WSNs signal transmission mechanism. Firstly,the sink node sended＂HELLO＂packet to construct the multi ring data transmission partition mechanism. Secondly,it proposed the waiting time form for data packet sending,meanwhile,through theoretical analysis and numerical analysis,it designed the multi ring poisson exponential distribution form of node energy consumption. The simulation test in the network simulator NS-2 shows that,this algorithm has more uniform energy distribution than the two existing algorithms,and also the longer network lifetime.
