推荐答案

从根本上说，信标只是一个重复的广播消息，它携带一些在发送者附近普遍感兴趣的信息.您可以在 Veins 中通过让您的应用程序每隔一段时间调用其 sendDown 方法来实现这一点.

Fundamentally, a beacon is simply a repeated broadcast message that carries some information of general interest in the vicinity of the sender. You can achieve this in Veins by having your application call its sendDown method every once in a while.
