中文说明：实现模拟DV跳定位，自动生成一定数量的节点分布，给出模拟结果的定位误差，图形显示，并可以计算平均误差。-DV-Hop模拟。生成一个随机分布的节点，然后进行仿真，给出每个节点的定位误差，如图所示
English Description：
Realization of simulation DV-Hop localization, automatically generate a certain number of nodes is distribution, gives simulation results of the location error, graph display, and you can calculate the average error. -DV-Hop simulation. Produce a randomly distributed nodes and then simulate and give the location error of each node, showing it in figur
