Collision protection based on packet error rate

A non-transitory computer-readable storage medium for use in conjunction with a transmitting electronic device, the non-transitory computer-readable storage medium storing program instructions to selectively enable use of pre-authorization messages, wherein, when executed by the transmitting electronic device, the program instructions cause the transmitting electronic device to perform one or more operations comprising:

• monitoring a performance metric associated with communication with a receiving electronic device;
• selectively enabling, based at least in part on a comparison of a threshold and the performance metric, transmitting of the pre-authorization messages for the receiving electronic device before communicating data with the receiving electronic device;
• communicating, via an interface circuit in the transmitting electronic device, the pre-authorization messages and associated data frames with the receiving electronic device;
• and
• selectively disabling the use of the pre-authorization messages based at least in part on the comparison of a pre-authorization threshold and a pre-authorization performance metric associated with the communication of the pre-authorization messages with the receiving electronic device, wherein the pre-authorization performance metric excludes contributions from the data frames, and
• wherein, if the use of the pre-authorization messages is selectively disabled, the transmitting electronic device reverts to monitoring the performance metric.

A method for selectively enabling use of pre-authorization messages, wherein the method comprises:

• by a transmitting electronic device:
• monitoring a performance metric associated with communication with a receiving electronic device;
• selectively enabling, based at least in part on a comparison of a threshold and the performance metric, transmitting of the pre-authorization messages for the receiving electronic device before communicating data with the receiving electronic device;
• communicating, via an interface circuit in the transmitting electronic device, the pre-authorization messages and associated data frames with the receiving electronic device;
• and
• selectively disabling the use of the pre-authorization messages based at least in part on the comparison of a pre-authorization threshold and a pre-authorization performance metric associated with the communication of the pre-authorization messages with the receiving electronic device, wherein the pre-authorization performance metric excludes contributions from the data frames, and
• wherein, if the use of the pre-authorization messages is selectively disabled, the transmitting electronic device reverts to monitoring the performance metric.
