Abstract: In wireless sensor networks,the node self-localization is vital and promising to a wide scope of both military and civilian applications.In this respect there are two types of algorithms,i.e.range-based and range-irrelevant,either has its own advantages and disadvantages.Taking account of those of the two algorithms,a low-cost and practical algorithm is proposed,using collation of RSSI(received signal strength indicator)for range measurement between nodes and optimization of beacon node in sensor network,then localizing nodes by weight centroid algorithm.Simulation results show that this algorithm has a better performance than classical RSSI algorithm.
