UDP实现可靠数据传输。使用GBN算法，实现了：1.随即丢包(随机数产生器Math.random()) 2.丢包后遇冗余ack重传 3.超时重传 (DatagramSocket和Socket都有成员函数setSoTimeout(delay),通过捕获超时时抛出的IO异常来实现超时重传)-Reliable UDP data transfer. GBN algorithm used to realize: 1. Then packet loss (random number generator Ma

网络损伤仪软件，绝对独家！！ 用来模拟网络对报文的损伤。从一个网卡上输入网络数据流，你可以自己随意模拟一定的延迟，模拟个性化的丢包，甚至抖动等，你要做的就是修改宏变量的参数即可。从另一张网卡流出的就是经过模拟损伤的网络流。只需要一台PC机就可以模拟例如路由器、交换机、无线网络等等可能带来的损伤，大大帮助研究和网络的开发和测试。一台硬件损伤仪市价至少五位数-Network Software injury, absolutely exclusive! ! Used to simulate the

一个随机丢包程序。用于检测自己的信道编码程序是否符合要求。-Procedures for a random packet loss. For detecting its own channel coding.

Sensor networks are a sensing, computing and communication infrastructure that are able to observe and respond to phenomena in the natural environment and in our physical and cyber infrastructure. In this paper, we investigate how the sensor netw
