| 摘 要： | 定位在无线传感器网络中非常重要,在DV-Hop定位算法中,平均每跳距离的计算误差过大.提出了改进的DV-Hop定位算法,结合较少跳数范围内加权的思想求解平均每跳距离,再乘以跳数,使其结果更加接近真实值.MATLAB仿真结果显示,改进的DV-Hop算法定位在不需要增加硬件开销的基础上增加了定位精度,定位误差明显减少.

| Abstract: | Abstract Localization in wireless sensor network(WSN) is very important. In the DV-Hop localization algorithm, average hop distance calculative error is too large. The average hop distance is solved with the improved DV-Hop algorithm combining with the idea of weighting in the scope of less jump number, which is then multiplied by hop to make the result closer to the real position. The MATLAB simulation results show that the improved DV-Hop algorithm can improve the localization accuracy effectively without increasing hardware consumption in nodes, significantly reduce the positioning error. |
