Research on Wireless Sensor Networks Localization Algorithm

Wireless sensor network is a new technology with sensation ability, the computing power and the wireless communication ability. On the basis of analysis of the existing positioning algorithm of wireless sensor network, this paper proposes a new algorithm based on RSSI positioning, and introduces a space formula stratified. The experimental results show that this algorithm can cope with tracking function better. Then the paper establishes anchor node network model, which achieves all the anchor stores in the layout, furthermore, determines the location of the node under test information on the basis of anchor of the network layout. Through the analysis of the error correction of blind nodes, this thesis proposes a new error checking method based on RSSI localization algorithm under test. Results show that the algorithm can reduce the calculation error in order to achieve good accuracy, with better reliability and applicability.
