This paper proposes a novel scheme to improve the fairness of active queue management congestion control. In order to reduce the increasing rates of packet loss caused by the exponential increase of network traffic, IETF (Internet Engineering Task Force) is considering the deployment of active queue management techniques such as RED (Random Early Detection). RED is a simple scheme, but it does ...

Active Queue Management (AQM) is intended to achieve high link utilization with a low queuing delay. Recent studies show that RED, one of the most well-known AQMs, is difficult to configure and does not provide significant performance gains given the complexity required for proper configuration. Recent variants of RED, such as Adaptive-RED are designed to provide more robust RED performance und...

We propose a model-independent multivariate sequential procedure to monitor changes in the vector of componentwise unconditional variances in a sequence of p-variate random vectors. The asymptotic behavior of the detector is derived and consistency of the procedure stated. A detailed simulation study illustrates the performance of the procedure confronted with different types of data generating...

Congestion is an important issue which researchers focus on in the Transmission Control Protocol (TCP) network environment. To keep the stability of the whole network, congestion control algorithms have been extensively studied. Queue management method employed by the routers is one of the important issues in the congestion control study. Active queue management (AQM) has been proposed as a rou...

The investigations for diagnosis and severity of OSA in Thai population need RDI from the PSG in sleep laboratory. The current problems of Thailand are firstly, inadequate sleep specialist and experienced technician: secondly, inadequate sleep laboratory result in long queue of appointments for sleep study. The authors proposed the new application for solving problem and developing to prioritiz...

Active Queue Management (AQM) is a very active research area in networking flows. In order to stem the increasing packet loss rates caused by an exponential increase in network traffic, researchers have been considering the deployment of active queue management algorithms. In this paper we will evaluate the active queue management algorithms such as Droptail, RED, BLUE, REM, GREEN and PURPLE. T...
