Abstract

Anchor plays a very important role in range-based localization algorithm. In order to solve disadvantages of traditional localization algorithm based on anchors, this paper proposes a new anchor-based localization algorithm for wireless sensor network. It optimizes anchors and creates an optimized anchors database. Anchors are chosen from the optimized anchors database to measure the distance between the unknown node and the anchor. Trilateration localization algorithm or Euclidean algorithm is used to locate unknown nodes. After unknown nodes have been located, they are used as new anchors so as to reduce the dependency of localization algorithm on anchors and the requirement that anchors should be uniformly distributed in the network. Simulation experiments results show that the new anchor-based localization algorithm can solve disadvantages of traditional localization algorithm based on anchors and can improve the localization accuracy.
