本程序是pgm算法的源码，用c＋＋和tcl编写在ns2作为工具-pgm algorithm source code, using c + + and peers prepared as a tool in NS2

omnet++，一个离散事件仿真器，主要用于模拟网络的，基于模块设计比ns2用起来容易上手-omnet, a discrete event simulation, which will mainly used to simulate network, Based on the module design together than with NS2 34.95

包含多个做网络编程时需要的NS2源代码，尤其对做路由，绝对值得参考-includes a number of network programming do need the NS2 source code, in particular the routing done, definitely worth considering
