Research of localization algorithm for wireless sensor networks based on Amorphous

Wireless sensor networks(WSNs) are used in various fields.Node localization information is the most important.Among all the classical localization algorithms,Amorphous is one of the range-free localization algorithms,by acquiring hops between unknown nodes and anchor nodes,and estimate the distances between nodes,then calculate coordinate of nodes.The disadvantages of Amorphous localization algorithm is analyzed,hop numbers between nodes are corrected.Centroid algorithm weighting is used to propose improved algorithm model,simulation verifies this algorithm can obtain accurate localization results.
