摘要

传感器部署区域障碍物的存在不仅会影响传感器节点之间的通信，而且会影响传感器的定位过程。本文提出了一种使用四个启用GPS的锚节点来定位障碍物和传感器节点的新方法。基于四个高能锚节点，对传感器进行定位，检测出每个障碍物的近似矩形边界。其次，基于每个障碍物相邻传感器节点之间的通信，通过优雅的启发式选择一种时间有效的方式进行障碍物周长的精确测量。仿真结果证明了所提方案的有效性和正确性，并在许多情况下得到了改进。

Sensor Localization and Obstacle Boundary Detection Algorithm in WSN

Existence of obstacles in sensor deployment region distorts the communication among sensor nodes and also disrupts sensor localization process. This paper represents a novel approach for localizing obstacles and sensors nodes using four GPS enabled anchor nodes. Based on four high energy anchor nodes, sensor localization is done, and an approximate rectangular boundary of each obstacle is detected. Next, accurate measure of the obstacle circumference is performed based on the communication between the neighbor sensor nodes of every obstacle in a time efficient manner, chosen by an elegant heuristic. Simulation results demonstrate the effectiveness and correctness of our proposed scheme, and improvement of our results in many cases.
