Patent ID: 7746787

Claim:
A process established between at least two devices, wherein each of the devices comprise a corresponding inbound queue for storing a sequence of DATA frames, the process comprising the steps of: communicating a value associated with each of the devices between the devices, the values comprising any of available stored energy for each of the devices, available operating time for each of the devices, and a priority value for each of the devices; comparing the communicated values; and providing asymmetrical transmission of RETRY frames to reduce transmissions from a chosen device of the devices, wherein the RETRY frames communicate a state of at least a portion of the inbound queue of a corresponding device, wherein the chosen device is determined to have any of less available stored energy than the other device, less available operating time than the other device, or a higher priority value than the other device; wherein the chosen device only sends a RETRY frame to the other device when a request for a RETRY frame is sent from the other device to the chosen device; and wherein the other device sends a RETRY frame to the chosen device upon any of when a request for a RETRY frame is sent from the chosen device to the other device, or when the other device times out waiting for a DATA frame from the chosen device.
