用的是GPSR_KeLiu_SUNY_Binghamton.tar 协议包。 GPSR协议nam演示图中节点无法移动，发现自带的运动场景文件中仅仅定义了节点的位置。然后我自己setdest生成了一个文件，结果还是无法移动，只看到一圈圈的扩散现象。哪位做过这方面的东西，麻烦指点下吧。不胜感激！ .tcl文件如下：（运动场景文件是没有问题的） # Copyright (c) 1997 Regents of the University of California. # All rights reserved. # # Redistribution and use in source and binary forms, with or without # modification, are permitted provided that the following conditions # are met: # 1.
