Active Queue Management (AQM) takes a trade-off between link utilization and delay experienced by data packets. From control point of view, it is rational to regard AQM as a typical regulation system. In this paper, a new fuzzy adaptive second order sliding mode controller is designed for the objective of AQM. In the proposed method, the sliding parameter is adapted using fuzzy logic. Some comp...

Denial Of service (DoS) attacks has become a major problem to intranet and Internet services. DoS attacks can be detected and eliminated using existing efficient Active Queue Management (AQM) schemes like RED. A new kind of DoS attacks have become more common in today’s Transmission control protocol (TCP) services, i.e., Low Rate Denial of Service (LDoS) attacks. LDoS attacks will degrade the p...

This paper presents a new active queue management (AQM) scheme, Fuzzy Explicit Marking (FEM), supporting explicit congestion notification (ECN), to provide congestion control in TCP/IP best-effort networks using a fuzzy logic control approach. While many AQM mechanisms have recently been proposed, these require careful configuration of non-intuitive control parameters, and show weaknesses to de...

Active Queue Management (AQM) can potentially reduce packet loss rate in the Internet. This is used by routers for control congestion, where packets are dropped before queues become full. In this paper, comparative study has been done using NS2 simulator. By examine five different AQM techniques i.e. RED, RIO, SFB, SRR and BLUE the performance of network has been evaluated on the basis of three...

This paper presents how generalized predictive control can improve the performance of TCP/IP networks when dealing with control congestion. Predictive control and GPC (Generalized Predictive Control), in particular, can be seen as an improved AQM (Active Queue Management) method. Predictive controllers, constrained and unconstrained, are compared with other control methods, such as PI control o...

para -Azaquinodimethane ( p -AQM) based quinoidal–donor (Q–D) polymers have been synthesized following a strategy for enhancing the backbone planarity and control bond length alternation (BLA).

Internet traffic is bursty and unpredictable. It is therefore important to control congestion to protect users from traffic surges in a way that is efficient, stable and robust. Research has shown that active queue management (AQM) has the potential to control congestion such that these requirements are met. However, despite much work and many published proposals of AQM algorithms, a satisfacto...

In order to prevent congestion, the current internet uses endto-end congestion control protocol like TCP. In congestion control issues, queue management employed by router has been utmost important. Active queue management (AQM) has been proposed as a router-based mechanism for early detection of congestion inside the network. AQM scheme helps for end-to-end congestion control by having routers...
