Abstract: A new algorithm based on interpolation and 0-1 programming was presented for three-dimensional localization in wireless sensor networks. In this algorithm, the spatial interpolation surface of the nodes is established by the anchor nodes coordinates, and the distances of all the communication nodes are derived from the received signal strength indication (RSSI) and empirical radio propagation model. The 0-1 program is used to select the interpolation nodes with the same number of unknown nodes on the space surface. These selected interpolation nodes will meet the distance constraint so as to estimate the unknown node location. The algorithm is simple in design and the communication overhead is low. Simulation indicates that this algorithm has less error in the node localization. It also has good stability and extensibility.

Key words: wireless sensor networks, localization, received signal strength indication, interpolation, 0-1 programming
