Abstract :
In order to solve the poor performance of location in RSSI localization Algorithm, caused by the link between anchor nodes and node to be positioning, this paper presents a positioning algorithm, which chooses anchor nodes based on Link quality Select strategy (LS) in a wireless sensor network. The method combines LS which plays a key role in localization with Weighted Centroid Localization Algorithm. The theoretical analysis and simulation results show that it raises the node ratio which can be located, and the accuracy of positioning can be well improved.
