Algorithm of Distribution Estimation for Node Localization in Wireless Sensor Network

Wireless sensor networks are distributed networks in the way to form wireless self-organization, using a large number of sensor nodes densely deployed in a specific area to monitor external data collection. Positioning accuracy of node becomes the determinants of the data reliability. In this paper, the node of wireless sensor network is located using the algorithm of distribution estimation to enhance the stability of measuring nodes, better improve the efficiency of node localization and reduce the positioning error and make the location having the conditions of parallel computing. Measurement errors can be completely filtered to get the physical location of node, no additional communication spending, and optimize network system.
