无线传感器网络拓扑边界辨识算法

在无线传感器网络（ WSNs）中，网络的拓扑特征对于设计网络应用和网络优化具有十分重要的意义。在拓扑特征中又以拓扑边界最为基础，不仅边界本身具有直接的利用价值，而且 WSNs瓶颈辨识、WSNs近凸分块等算法都需要以获取边界信息为前提。提出了一种不依赖地理信息的分布式算法，通过借鉴自然现象热传导的规律和等温线只在边界中断的固有特点，在WSNs这一人工系统中模拟热传导过程，最终成功地辨识了WSNs的边界。

Topological boundary identification algorithm for WSNs

In wireless sensor networks( WSNs),topological characters of WSNs is important for application and optimization of designed network. Topological border is the basis of topological characters,it can be used directly, and WSNs bottlenecks identification and near convex segmentation algorithm are both rely on boundary information aquiring. Propose a distributed algorithm which is independent of geographic information to successfully identify WSNs boundary by rule of heat conduction of natural phenomena and natural characteristics of isotherm breaks off only on boundary for reference,in WSNs which is an artificial system simulate heat conduction process.
