We present a novel active queue management (AQM) technique to demonstrate the efficacy of practically harnessing the predictive utility of SSR indications for improved video communication. We consider a network within which corrupted packets are relayed over multiple hops, but a certain percentage of packets needs to be dropped at an intermediate node due to congestion. We propose an AQM techni...

Introduction: As a representative active queue management (AQM) scheme, random exponential marking (REM) [1] faces the challenge of dynamically tuning its parameters to satisfy the stability requirement under various network conditions adaptive to network conditions [2, 3]. In [4], Deng et al. proposed an adaptive control mechanism for the proportional and integral (PI) controller based AQM (PI...

Concerns over the scalability of TCP’s end-to-end approach to congestion control and its AIMD congestion adaptation have led to proposals for router-based congestion control, specifically, active queue management (AQM). In this paper we present an end-to-end alternative to AQM—a new congestion detection and reaction mechanism for TCP based on measurements of one-way transit times of TCP segment...

This paper shows the design and performance of an AQM (Active Queue Management) enabled router. The design is based on a classical proportional control system. The application of such a router is to enhance streaming media over IP performance by avoiding bursty packet drop situations, control the router queue delay, and balancing packet drop, delay, and link utilization. The selected AQM equili...

Today’s handheld computing devices equipped with novel wireless network technologies can provide their users with features such as mobility, multimedia support and group communication. On the other hand, the administrative effort required to enable all these features increases beyond the level that an ordinary user can manage. Ad hoc networks, being able to quickly organise themselves without u...

QUALITY-OF-SERVICE-AWARE MULTICAST ROUTING FOR MULTIMEDIA APPLICATIONS IN MOBILE AD HOC NETWORKS The conceptual shift in the expectations of wireless users towards multimedia and group-oriented computing has a significant impact on today’s networks in terms of need for mobility, quality of service (QoS) and multicast routing. Mobile ad hoc networks can provide users with these features. However...

This paper presents the LQ-Servo control with observer for TCP/AQM system. In order to estimate the state of TCP window packet size, the control structure is extended with observer based on Kalman filter.

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 ...
