| Abstract | Aiming at improving the precision of nodes’ localization, this paper analyses the source of the localization error when using least square algorithm, and proposes the principle to choose the benchmark anchor nodes in reducing the power of equation. Based on this principle, the algorithm choosing the nearest node as the benchmark anchor node in least square algorithm and the algorithm choosing the synthetic nearest node as the benchmark anchor node in least square algorithm are put forward. It is proved by the simulation in MatLab that the improved least square algorithm can effectively improve the precision of the nodes localization. |
