A Localization Algorithm of Nodes based on Hypersphere Granular Computing in Wireless Sensor Networks

摘要

This paper proposes a node localization algorithm based on super chondritic calculation, super chondritic calculation scanning of a training set is able to complete the training process, the training has characteristics of fast, the problem of node localization for wireless sensor networks. Firstly, according to the related parameter information for the location of wireless sensor nodes, a multi input, multi output problem of training set, and then through the methods of grid division, location area, the original training set into the classification of multi input, single output training set, the super chondritic algorithm by scanning training, in order to get the relevant parameters, and the estimation of the unknown node location. Simulation results show that the proposed algorithm has better positioning accuracy.
