实用的POS终端向后台进行签到程序的代码，提供了参数配置，日志文件记录等附加功能，C语言实现，实现了POS终端向后台发送签到请求报文，并接收后台返回的签到响应报文，从而获取工作密钥的整个过程。

linux下模仿wireshark进行抓包, 并作简答分析. 并模拟ping, 向目标地址发送icmp请求包.

法语用户提交的代码，有兴趣的朋友可以下来看看。暂时不支持法语-中文的翻译。

这个程序的结构比较简单，只实现了open(),ioctl(),close()功能，其中最主要的就是ioctl()功能，在ioctl()中最重要的核心函数为

如何衡量吞吐量、 丢包率和基于 UDP 的应用程序的端到端时延，通过无线网络？ [场景] 它是由 8 个移动节点： 4 源节点和 4 的目标节点。每个源是 CBR 通过 UDP。传输的数据包的大小为 512 字节。一个节点的传输速率是 600 Kbps。我们假设节点处于传输范围在恒定195 米的距离。仿真时间持续 80 秒。
