| 摘 要： | 主要介绍了MDS-MAP算法在通过4种不同传播模型时定位误差的不同,通过仿真可以看到MDS-MAP算法在各个传播模型中的定位误差图。从仿真结果可以得出,在环境好的情况下,规则模型与不规则模型的定位误差相差不大,当环境变化时,不规则传播模型比规则传播模型更能适应恶劣的环境。介绍了两种情况,随着环境的改变,传播模型相关参数也会有所改变进而影响定位误差的变化。

| Abstract: | The localization error of the MDS-MAP algorithm was introduced in four different propagation models.Through simulation we could see the localization error chart of the algorithm in each of the propagation model.Simulation results also showed that in a good environment,there was no significant difference in the localization error in a regular model and an irregular model.When the environment changed,however,the irregular model was more adaptable than the regular one.Here we just introduced two kinds of situations.As the environment changes,the parameters related to the propagation model also change and will affect the change of the localization error. |
