| 摘 要： | 无线传感器网络中网络拓扑对配置网络资源、优化网络性能具有十分重要的作用.根据在汇聚节点收集到的网络节点报文接收/丢失的信息,提出了一种基于数据聚合的分层拓扑发现算法,该算法同时可以实现对传感器网络节点的分层.针对目前的拓扑发现算法在网络链路丢包率较低的情况下无法快速推断出网络拓扑的问题,提出了一种使部分节点进入睡眠状态的方法推断低丢包率条件下的网络拓扑.仿真结果表明,提出的算法可以利用较少的观测数据准确快速地推断传感器网络的拓扑.

| Abstract: | Sensor network topology plays an important role in resource management and deployment.By using the lose/receive information of data collected in the sink,we proposed a level-topology identification algorithm based on data aggregation in this paper,and we can get the level information of the sensor network in the same time.Considering the low speed of all topology algorithms proposed when the loss rate of sensor network is low,we proposed a method which put some nodes into sleeping state to inferring the top... |
