2559e27414 API change to the announcement module: an annoucement can now be registered without a value. Such announcements are never transmitted to neighbors, until the announcement's value is set. 2010-03-25 08:49:56 +00:00

137e02baac Added a bump method that tells the announcement module that a value has changed sufficiently much for it to be pushed out quicker 2010-03-19 13:16:11 +00:00

a4d9d6651b Added the option to specify the old value to observers so that they can determine if the announcement should be sent out quicklier than otherwise 2010-02-23 18:32:44 +00:00

be846d8c90 A new experimental network primitive called an 'announcement'. An
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.
