The application of algebraic reconstruction techniques to DV-Hop location algorithm

In the field of wireless sensor network, positioning accuracy of the sensor in a network is directly related to the method for getting of or computing the data of sensor positions. An algebraic reconstruction technique based DV-Hop location algorithms is presented in order to reduce the localization error and much consume in computation of original DV-Hop localization algorithm based on the least square method principle. The analysis and simulation shows that the presented algorithm has obviously reduced the average localization error in the wireless sensor network.
