主　　题：Wireless sensor networks(WSNs) adaptive cooperative location positioning precision received signal strength indication(RSSI) Dixon method 

摘      要：To overcome the disadvantages of the location algorithm based on received signal strength indication(RSSI) in the existing wireless sensor networks(WSNs),a novel adaptive cooperative location algorithm is *** tolerate some minor errors in the information of node position,a reference anchor node is *** the other hand,Dixon method is used to remove the outliers of RSSI,the standard deviation threshold of RSSI and the learning model are put forward to reduce the ranging error of RSSI and improve the positioning precision *** are run to evaluate the performance of the *** results show that the proposed algorithm offers more precise location and better stability and robustness.
