| 摘 要： | 提出一种基于数据汇聚的传感器网络链路报文丢失率推测算法，利用在汇聚节点观测到的父子节点报文接收数量的差异，通过简单的数值计算快速地推测逻辑链路的报文丢失率。仿真结果与理论计算结果相比表明，算法能够较准确地推测出逻辑链路上的报文丢失率，实时性好。

| Abstract: | This paper proposed a method based on data aggregation to estimate the link loss rate, which could estimate the link loss rate quickly by simple numerical calculation based on the number of packets accepted by the sink node between a child node and its parent node. Through the simulation, it could be safely concluded that the internal link packet loss rate could be inferred quite accurately, comparable to the sampled internal link packet loss rate. The simulation also shows that the proposed algorithm has better real-time characteristic. |
