#采用一个有3个移动节点的实例来讲解利用NS2进行无线网络模拟的具体流程，场景设置为

#一个500mx400m的矩形区域中

#移动Adhoc网络使用DSDV路由算法，三个节点的初始位置分别设置为(5,5,0)、(490,285,0)

#和(150,240,0)，然后再适当的时候设置它们移动方向、速度。并在节点0和节点1之间尝试-# Using an instance of the mobile node the NS2 to explain the use of the wireless network simulation process, the scene is set for Mobile Adhoc## a 500mx400m of the rectangular area network using DSDV routing algorithm, three nodes are set to an initial position (5,5,0), (490,285,0)# (150,240,0), and then set their direction of movement, then the appropriate speed. And try to nodes 0 and 1
