Abstract
A method and apparatus for automatically switching functions associated with a leading radio to another radio on a channel is disclosed. The method includes receiving, from a leading radio by at least one other radio operating on a channel, an associated timing signal via at least one control timing message. Other radios use the timing signal to synchronize transmissions made on the channel. The method also includes receiving, by the other radios, an indication that the leading radio can no longer provide control timing messages. The method further includes maintaining, by each radio on the channel, values for various elements associated with radios operating on the channel and selecting a new leading radio from the other radios based on priorities of the various elements.
