A low power consumption protocol (400) for low power communication devices (410,420) attached to an asynchronous network (440) is described. In this protocol, a communication device (410) is used as a high communication duty cycle Mediation Device (MD-430), thus permitting other communication devices (420) to use a low communication duty cycle framing structure. The MD (430) functions as a storage and retrieval service for messages between two devices (410,420) when one device is not able to communicate. When the previously unavailable device (420) becomes available, it can check in with the MD (430) to retrieve any missed messages and respond to these messages accordingly. In a communication network (400), each of the low power communication devices (410,420) can be configured to behave as MD's (430) for a small amount of time. Sharing this responsibility among all communication devices (410,420,430) in the network (400) allows each device (410,420,430) to maintain an low average communication duty cycle. This technique is applicable to a low power, low cost, zeroconfiguring, self-organizing, asynchronous network (400). |
