Claim:
1. A method, comprising: determining a scheduled window within which a packet should be transmitted by an intermediate node in a contention-based shared-media computer network, the packet having an assigned priority, wherein the window accounts for an expected number of retransmissions (ETX), a wait time and receipt of an acknowledgment; determining whether an actual transmission time is prior to, during, or after the window; in response to determining whether an actual transmission time is prior to, during or after the window, dynamically adjusting a priority of the packet in a header of the packet as either i) a reduced priority when the actual transmission time is prior to the window, ii) the assigned priority when the actual transmission time is during the window, or iii) an augmented priority when the actual transmission time is after the window; and transmitting the packet from the intermediate node with the set priority at the actual transmission time.
