Simple Algorithm for Outdoor Localization of Wireless Sensor Networks with Inaccurate Range Measurements

Abstract— We consider the problem of determining the positions of wireless nodes using range measurements from multiple, sparsely located, beacon stations with known locations. A large number of such nodes surrounding the beacon stations automatically and cooperatively estimate their position through collaborative efforts and iterative refinements. These positions are propagated to other nodes in the network, allowing the entire network to create an accurate map of itself. The proposed approach features robustness with respect to range measurement inaccuracies, low complexity and distributed implementation, using only local information.
