中文说明：aloha协议仿真，假设是无限呼叫源模型，接入点收到信息后应答，发生碰撞时，接入点无法应答，过一段时间，再随机重发，直到接入点应答为止，终端与接入点之间可以是有线信道，也可以是无线信道
English Description：
ALOHA protocol simulation, assuming that it is an infinite call source model, the access point will respond after receiving the information. In case of collision, the access point will not be able to respond. After a period of time, it will be retransmitted randomly until the access point responds. Between the terminal and the access point, it can be a wired channel or a wireless channel
