【 摘 要 】

In this paper,we analyzes and simulates DV-Hop algorithms based on the least square estimation frame.The accuracy of the algorithms depends on the information of jump number among beacon nodes.To overcome this drawback,we presents an improved algorithm of error correction DV-Hop (ECDV-Hop).The simulation results show that,in the same indoor environment,the positioning accuracy of ECDV-Hop algorithm is higher than DV-Hop algorithm.
