Differentiating Services for Sensor Internetworking

We propose NCQ (Non-Congestive Queuing) as a scheduling discipline that allows for efficient interoperation of sensor networks with the Internet. NCQ promotes conditionally small data packets, which require comparatively minor service times, as long as their total service times cause insignificant delays to other packets in the queue. Therefore, NCQ introduces a new service philosophy, which prioritizes packets, and in turn corresponding flows, according to their impact on total delay. In this context, we also introduce a corresponding index to measure fairness as a function of the deviation of expected and received delay.
