碩士 === 國立屏東商業技術學院 === 資訊工程系(所) === 100 === Localization is an important issue in wireless sensor networks (WSNs). Because the sensor nodes are randomly distributed in a region for forming a WSN, we have to identify the location of a sensor node and immediately realize the surrounding circumstances of the sensor node. This thesis presents exploiting the equipment of the rotating directional antenna on the mobile beacons helps each sensor node to determine its location information. The sensor node calculates its location information through the periodical broadcast position information of the mobile beacons. The proposed localization is evaluated through the network simulator ns-2 and the simulation results show that the sensor node can estimate its location successfully.
