Overview of Node Localization Algorithms in Ad-hoc Network

The mobile node makes a broad application prospect of the Ad-hoc network in many modern fields, such as the military, the medical and environmental protection. However, with the increase requirement of mobile-node location information by the people, the node localization has become a focal problem in Ad-hoc network. Nowadays, there are many kinds of node localization systems and algorithms. Based on the classification of the localization algorithms, the procedure of the node localization is divided into 4 steps and some of the representative algorithms are analyzed in detail. Finally, a standard for evaluating the performance of node localization algorithms is proposed.
