Summary:
This paper proposes algorithms for preventing congestion and assigning the priority to the important events. Most existing algorithms use the backpressure messages to control the rate of sources. In contrast with them, proposed novel algorithm prevents from congestion previously using queue monitoring. Proposed algorithm is composed of 3-states, Non-Congestion state, Pre-Congestion state and Congestion state. Each state has own algorithm and congestion is prevented by them. In addition, each node has two queues, one for the RT[real-time] event and the other for the NRT[non real-time] event, to control each event efficiently and give priority to the RT event.
