**ABSTRACT:**Target localization and tracking have been an important fundamental technology in wireless sensor networks. Distance irrelevant localization algorithm is one of the most popular methods in target localization application. This kind of algorithm mostly locates a target by getting the target's approximate area and calculating its centroid. Because of the large calculating quantity and bad real-time capability of the traditional methods in solving the centroid of irregular approximate area, a universal Adaptive grid Division (AID) method was proposed. By grid dividing and scanning towards the WSNs deploying area, a target approximate area was got and the localization precision was adaptively adjusted according to the grid granularity. The results of experiment showed that AID had a higher real-time capability under similar precision with traditional methods.Computer Science and Network Technology (ICCSNT), 2012 2nd International Conference on; 01/2012 -
##### Conference Paper: A new approach of double-level grid-based target localization in wireless sensor networks

**ABSTRACT:**Target localization is one of the most important and fundamental issues in wireless sensor networks (WSNs). Because of its special topology structure, grid-based wireless sensor networks have a great advantage in target localization. In this paper, firstly, we analyze the uncertain area founded by the topology structure of single-level grid-deployed networks. A double-level grid-based localization method is proposed, which is theoretical and practical. We consider the computational complexity of the algorithm and define its localization error in both single-level and double-level grid-deployed networks. Simulation results reveal the general rule between different factors and their influences on location accuracy, which is meaningful to the real application of our method. The results prove that double-level grid-based localization method can not only keep location precision to a certain extent, but is also real-time and practical.Sensors, 2012 IEEE; 01/2012 -
