摘要：Wireless sensor networks (WSNs) have been widely used in many applications. The highly correct location information of sensor nodes is crucial for these applications. Nowadays there are mainly two types of localization algorithms: Range-based localization algorithms and Range-free localization algorithms. The drawback of former type is strict requirements on the hardware configuration. The latter type is cost-effective alternative approach. However, this approach can achieve high accuracy only in some ideal scenarios, and some methods even require a lot of complex calculations. In this paper, we put forward a novel PAV-based Calibration localization method (PAVC) locating the unknown nodes. The Pool Adjacent Violators (PAV) algorithm can be used to calibrate the average distance per hop of hop-based positioning algorithm. PAVC improves the localization accuracy compared with previous hop-based algorithms, which is demonstrated by the simulation and testbed results. Copyright ? 2010 ACM.
