摘要: |
对现有基于最小二乘法的DV-Hop定位算法进行分析和仿真,针对该算法定位精度依赖信标节点之间跳距和跳数这两个信息的不足,给出一种可对信标节点之间的跳距和跳数关系做出误差修正的改进的误差修正DV-Hop(ECDV-Hop)算法.仿真结果表明:在相同的室内环境下,ECDV-Hop算法与传统DV-Hop算法相比,定位精度得到一定的提高. |

Abstract: |
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. |
