announcement is an (ID, value) tuple that is disseminated to local area neighbors. An application or protocol can explicitly listen to announcements from neighbors. When an announcement is heard, a callback is invoked. Announcements can be used for a variety of network mechanisms such as neighbor discovery, node-level service discovery, or routing metric dissemination. Application programs and protocols register announcements with the announcement module. An announcement back-end, implemented by the system, takes care of sending out announcements over the radio, as well as collecting announcements heard from neighbors.
