This paper identifies the lone linear drop function for computing dropping probability between certain queue threshold values as a major weakness random early detection (RED) algorithm it leads to large delay and instability. To address this concern, we propose an enhanced RED-based called detection-quadratic (referred “RED-QL”) active management (AQM) which leveraged benefit of quadratic packe...

In recent years, AQM (Active Queue Management) mechanisms, which control the number of packets in the router’s buffer by discarding an arriving packet, have been actively studied. In past studies, most of AQM mechanisms have been designed by taking account of a single router; i.e., few AQM mechanisms have been designed by taking account of multiple routers in the network. In a general network w...

<p>The wireless network transmission control protocol/active queue management (TCP/AQM) is a that was chosen as topic for research basis laid to simulate the proposed and conduct simulation under certain conditions. To manage protocol chosen. The solution many modern systems depends on placing additional units called controllers, which work improve performance of systems. current system c...

The congestion is the most important issue that effects on performance of data transition over internet networks. One techniques developed active queue management (AQM) prepares an efficient control by reducing losing packets, size, and energy consumption. Therefore, AQM technique deemed as a base many algorithms schemes. This work suggested using proportional integral (PI) controller then use ...

This talk reports on an analytic derivation of the complete stability region of the Proportional Integral (PI) Active Queue Management (AQM). The stability region represents the entire set of the feasible design parameters, i.e., the proportional and the integral gains, that stabilize the closed-loop TCP-AQM system. AQM controls congestion by proactively marking or dropping packets before the i...

With the network architecture more and more complex, it is an interesting problem how to cooperate many routers working in the multilayer network simultaneously. Since these AQM (Active Queue Management) algorithms based on the single router have not considered the link capacity of connected routers, there are some disadvantages, e.g., it is difficult to deal with the congestion problem effecti...

Active Queue Management (AQM) schemes aim to stabilize router queue sizes and provide better fairness among a set of TCP connections. Random Early Detection (RED) is one of the first and well-known AQM schemes. Explicit Congestion Notification (ECN) is a modified version of RED in that it notifies a sender about congestion, instead of dropping its packet. Under such AQM schemes, TCP connections...

Routers are vital during network congestion. All routers have input and output packet buffers. V<span lang="EN-US">Various congestion control strategies been suggested. Some controller-based proportional-integral derivative (PIDs) recently offered as active queue management (AQM) solutions to alleviate the deterioration of transmission protocol (TCP) system performance. However, time dela...

Wireless Body Sensor Networks (WBSNs) involve a convergence of biosensors, wireless communication and networks technologies. WBSN enables real-time healthcare services to users. Wireless sensors can be used to monitor patients’ physical conditions and transfer real time vital signs to the emergency center or individual doctors. Wireless networks are subject to more packet loss and congestion. T...

Several fair queueing mechanisms based on stateless core (SCORE)/dynamic packet state (DPS) architecture have been proposed to address the scalability problem of stateful architectures. However, most of these mechanisms indiscriminatingly label every packet in edge routers while only a small fraction of the packets that come from fast flows will be dropped by core routers. Moreover, these mecha...
