ABSTRACT
A new distributed mobile anchor-assisted localization algorithm using anchor-density-based clustering for wireless sensor network was proposed. In the algorithm, the mobile anchor equipped with Globe Position System (GPS) move around in the Wireless Sensor Network (WSN) field, the network was divided into many clusters and each cluster was belong to one of three grade by core density. Mobile anchor node was played different role in different cluster grade, in high-density cluster, mobile anchor only was used for error correction; in low-density cluster, mobile anchor was used to computing average distance and error correction; while in sparse-density cluster, mobile anchor only was used to compute average distance. Simulation results show that the localization accuracy of the proposed algorithm in irregular network is better than the DV-Hop algorithm and the average traffic is lower than the traditional DV-HOP algorithm.
