A Distributed 3 Dimension Relative Localization Algorithm for Mobile Wireless Sensor Networks

Position information of individual nodes is very useful in implementing functions such as routing, querying and many applications. Researchers have proposed several location techniques but only a few relative location algorithms for mobile wireless sensor networks (WSNs). Although mobility would appear to make localization more difficult, this paper introduces a distributed 3 dimension relative localization algorithm for the mobile WSNs. This approach is an effort in finding a solution to positioning problem for highly dynamic nodes deployed randomly in a complex environment and the 3 dimension coordinate provided can be satisfied with great applications. The distributed coordinate transformation algorithm takes lower convergence times in the establishment of the global coordinate system.
