Abstract

In wireless sensor network localization, many anchor nodes and target node exchange information at specified time intervals to obtain the distance information between each anchor node and the target node. With this information, the coordinates of the target node can be achieved through the calculation of the positioning algorithm. However, as there are numerous negative factors like non-line-of-sight measurement, complex multipath fading, which leads to high-level localization error. To improve localization accuracy, an improved least square localization algorithm is proposed, which combines the least square localization method with the statistical filtering optimization strategy. The simulation results show that this algorithm can effectively reduce localization error and achieve more accurate localization.
