Further, the one or more network interfaces of the device can be configured based on service levels for portions of the communication activity in order to regulate the thermal conditions. In some example implementations, instructions can be sent to another device communicating with the networking device to modify communications in order to regulate the thermal conditions.
An example method may include identifying a first transmit identifier (TID) associated with a first node of a wireless network as ready to transmit and adding the first TID to a ready to transmit queue at a first point in time. The method may also include identifying a second TID associated with a second node of the wireless network as ready to transmit, and adding the second TID to the ready to transmit queue at a second point in time later than the first point in time. The method may additionally include selecting the second TID from the ready to transmit queue before selecting the first TID based on a projected increased overall throughput of packets within the wireless network when communicating with the second node before communicating with the first node.
