Improved Localization Algorithm in Wireless Sensor Networks

In the wireless sensor networks, the node localization is a hotspot research. This paper does theoretical analysis of the DV-HOP algorithm and brings an improved algorithm. To use correction value as estimated distance between anchor nodes and unknown nodes. Meanwhile, TLS is applied to node localization algorithm to make further localization accuracy. By means of MATLAB emulation, it is proved that the improved algorithm of this paper gives better localization accuracy results than original algorithm and other existing improved algorithms.
