Improvement of DV-Hop localization algorithms in wireless sensor networks

The traditional DV-Hop algorithm is not high accuracy features in the detailed analysis of the DV-Hop algorithm is based on the step, the paper proposes two new DV-HOP algorithms. Firstly introduce the weighted averaged method calculated for each hop distance, secondly approximate estimate beacon nodes and unknown nodes distance, then using this distance to calculates average every hop distance. Results: In the same scale network, improved DV-HOP algorithm, the sensor node localization accuracy than the traditional DV-HOP algorithm more idealistic.
