Abstract :
The node localization algorithm is one of the key technologies in WSN. In the paper, a Weighted DV-HOP algorithm is proposed based on traditional DV-HOP algorithm. And a improving simulation model is employed to confirm the changes of localization accuracy. Comparing DV-HOP algorithm, simulation shows that the WDV-HOP algorithm can increase localization accuracy by above 2% with the same conditions which includes the percentage of anchor node, the scope of radio range and the network connectivity. Conversely, under the same accuracy request, the number of percentage of anchor node can be reduced obviously to lower the network investment cost.
