In the paper, a new framework of active queue management, namely, edge-based active queue management (EAQM), is proposed. Conventional AQM schemes are required to be deployed at all routers in the network, and this involves significant upgrading to current drop-tail routers. The new approach only needs to modify the edge routers and at the same time provides similar or better performance as com...

Fuzzy logic has been widely used to develop an adaptive traffic signal controller because it allows qualitative modelling of complex systems. However, existing research has developed Fuzzy Logic Traffic Signal Controller (FLTSC) based on non-mixed traffic conditions. These FLTSC are not appropriate to the mixed traffic conditions of developing countries where the traffic streams consist of diff...

conclusions: the patients' waiting times and the number of patients waiting to receive services in both shifts could be reduced by using multitasking persons and reallocating them to the time-consuming stage of filling prescriptions, using queuing theory and simulation techniques. background: hospital pharmacy is responsible for controlling and monitoring the medication use process and ensures ...

With the exponential growth of the Internet traffic, congestion problems become severe. To solve these severe problems, the Internet Engineering Task Force (IETF) recommends implementing the Active Queue Management (AQM) mechanism on the Internet routers. This paper introduces a robust AQM algorithm, called Adaptive Fuzzy Proportional Integral Derivative (AF-PID), which adaptively tunes the par...

Active queue management (AQM) is a group of FIFO based queue management mechanisms in a router to support end-to-end congestion control in the Internet. Until random early detection (RED) was proposed by the internet engineering task force (IETF) for deploying[1], FIFO based tail drop (TD) was the only AQM mechanism used in the network. Two main functions are used in AQM: one is the congestion ...

A Mobile ad-hoc network (MANET) is a self configuring infrastructure less network of mobile devices connected by wireless links. In MANET the proper maintenance of resources and link to avoid congestion is main issues. In this paper our motive is to get better utilization of resources and avoid congestion. For communication system uses queuing techniques, Traditional queuing techniques like Dro...

in order to make the best utilization of a link in computer networks, active queue management (aqm) algorithms are generally used in a variety of methods. in this paper, a systematic control strategy based on self-scheduled h ∞, considering the dynamics of the window-based tcp flow, is proposed. then, the robustness of the designed controller to disturbance and parameter fluctuations of the pla...
