In WMNs, however, these packet losses are spatially distributed over various intermediate routers (see Section 2) and cannot be accurately predicted by simply monitoring the queue size at the gateway router.
The strategy proposed in this paper is a fine grain approach, which aims to optimize the data rate of data service by monitoring the job queue.
By monitoring the rate of change in queue length (variation rate) in addition to the queue length, FuzzyQoS provides a measure of queue state.
By monitoring the number of packets in queue, the congestion degree and the average cumulative queue length, a node informs its neighbors about both the distance cost from itself to a sink and possible congestion.
By monitoring the dynamics MAC's AC queues, each AC figures out during runtime the TXOPlimit's value that best accommodates the application's data rate.
A total of 1,297 people were queueing as the doors opened at 8.01am, according to researchers from 63336, a question-and-answer service that has monitored the queues for Apple launches over the past few years.
By monitoring queue drops at the gateway, we found that the FRED queue did register some proactive packet drops for f1 and f2, though it was insufficient to preclude the starvation of f3. Figure 4 shows the per-flow data arrival rate (not ACKs) in the FRED queue at the gateway during our simulation.
A deputy sheriff monitoring the good-natured queuing joked, "I feel like I'm at Disney World".
Condor-COPASI monitors the status of each submitted job – the queue of jobs is periodically polled to check for jobs marked as 'held', and the exit status of all completed jobs is checked (a non-zero exit status indicates an error) by parsing the log files.
