该压缩包是有关LEACH协议的源程序，在此之前应该安装ns2和cygwin.

NS2更适合在linux操作系统下运行，然而大多数人对linux操作系统不太熟悉更习惯于windows操作系统，所以就需要把NS2安装在windows平台下，前提条件是先安装一个cygwin模拟Unix系统软件.

-The compressed package is about the source LEACH agreement before the installation of ns2 and cygwin.NS2 should be more suitable in the linux operating system, but most people are not familiar with the linux operating system more accustomed to windows operating system, so NS2 need to be installed in the windows platform, a prerequisite is to install a cygwin simulated Unix system software.
