Wireless Sensor Network (WSN) is an emerging network technology. Among the varying research focused upon WSN, Location-Aware is a topic worthy of study. We are putting forward a hierarchical localization 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 measurement error value from the survey distance between two nodes by way of simple statistics and then correcting the survey distance to get a more accurate node location; second, using relaying nodes to fulfill hierarchical positioning strategy. The advantage of these methods is that they can reduce cost in the considerable extra hardware common in sensor networks. Through simulation experiment, the evidence confirmed the proposed methods can effectively improve localization accuracy and enhance the localization rate of estimated nodes.
