【摘要】 对随机分布的无线传感器网络中的节点流量因子、汇聚因子和桥接因子进行了理论建模,在此基础上提出了关键节点的理论判据和发现算法.通过实验模拟,发现通过该方法识别出来的关节点是对网络生存期影响最大的节点.通过该方法,可以快速找出传感网中的热点区域和关节点,为提高无线传感网生存期提供了重要的理论依据.更多还原

【Abstract】 This paper presented a WSN node’s theoretical mode,which includes traffic factor,aggregation factor and bridging factor,and then constructed an articulation-node’s determination and discovery algorithm.Experiment results have shown that the invalidation of nodes identified by the model will have a serious impact on the connectivity of the network.By using this method,we can quickly identify the hot spots in WSN.更多还原
