Abstract: Wireless Sensor Network (WSN) is an emerging network technology. Among the varying research fo¬cused upon WSN, Location-Aware is a topic worthy of study. We are putting forward a hierarchical localiza¬tion strategy. By using wireless localization and a few GPS, sensor networks can be more economical and localization can be more accurate. Our strategy includes two aspects: first, getting a relatively good measure¬ment error value from the survey distance between two nodes by way of simple statistics and then correct¬ing the survey distance to get a more accurate node location; second, using relaying nodes to fulfill hierarchi¬cal positioning strategy. The advantage of these methods is that they can reduce cost in the considerable ex¬tra hardware common in sensor networks. Through simulation experiment, the evidence confirmed the pro¬posed methods can effectively improve localization accuracy and enhance the localization rate of estimated nodes.
