A Survey on Localization Algorithms for Wireless Ad Hoc Networks

In wireless ad hoc networks, location service is used to confirm geographical position and data information of a specific node for efficient routing. However, since in some specific circumstances ad hoc network localization cannot just rely on global positioning system (GPS), self-localization algorithm is a focus during wireless ad hoc research process and supplies solution for the problem. This paper integrates some existing prevalent self-localization algorithms and introduces some representative algorithms, then evaluates the algorithms and makes a comparison, at last educes a conclusion.
