Prioritized queueing in a mesh network based on age of payload data

In one embodiment, a method comprises identifying an age of payload data in a data packet by a wireless network node configured for transmitting the data packet to a multi-hop destination via a wireless mesh network; determining by the wireless network node a schedule for the data packet reaching the multi-hop destination; and the wireless network node prioritizing queuing of the data packet for Collision Sense with Multiple Access and Collision Avoidance (CSMA-CA) based wireless transmission in the wireless mesh network based on the corresponding age, relative to the schedule and respective ages of other data packets awaiting transmission by the wireless network node to the destination, where a higher-aged data packet relative to the schedule is granted have a higher priority than a lower-aged data packet relative to the schedule.
