QoS provisioning in multimedia streaming
… movies on demand. Providing Quality of Service (QoS) for multimedia streaming has been a difficult and challenging problem. When multimedia traffic is transported over a network, video traffic, though usually compressed/encoded for bandwidth reduction, still consumes most of the bandwidth. In …

QoS Provisioning for Multi-Class Traffic in Wireless Networks
… the difficulty of providing Quality of Service (QoS) guarantees in wireless networks. There is a growing demand for wireless networks to support all the services that are available on wired networks. These diverse services, such as email, instant messaging, web browsing, video conferencing, …

Enhancing QoS provisioning and granularity in next generation internet
… and deployed, and demand Quality of Service (QoS) support from the Internet, in addition to the current best effort service. Therefore, QoS provisioning techniques in the Internet to guarantee some specific QoS parameters are more a requirement than a desire. Due to the large amount of data …

Delay QoS Provisioning and Optimal Resource Allocation for Wireless Networks
… systems require certain quality of service (QoS) constraints e.g., in terms of delay, buffer overflow or packet drop/loss probabilities, so that acceptable performance levels can be guaranteed for the end-users, especially in delay sensitive scenarios, such as live video transmission, …

Multi-stage queuing with iterative probabilistic scheduling of IP traffic for QoS provisioning
… functions which provide quality of service (QoS) at the first level of the QoS architecture where routers reside. With the continued increase in network speed, queuing and scheduling of traffic needs to be performed at higher speed. In addition, processing co-existing IP traffic from …

Efficient joint call admission control and bandwidth management schemes for QoS provisioning in heterogeneous wireless networks
… radio resource management (JRRM) for enhanced QoS provisioning and efficient radio resource utilization. Joint call admission control (JCAC) algorithm is one of the joint radio resource management algorithms. The basic functions of a JCAC algorithm are to decide whether or not an incoming call …

A calculus for stochastic QoS analysis and its application to conformance study
… applications which need Quality of Service (QoS) guarantees. Many schemes have been proposed for QoS provisioning in computer networks. It is important to evaluate the performance of these QoS provisioning schemes. In this thesis, a stochastic network calculus is proposed to systematically …

Resource management in the future internet
… fast Internet growth has led to high demands for QoS provisioning mechanism to be implemented in the future Internet This dissertation presents the development and implementation of a resource reservation scheme to allocate and manage resources in the future internet. Resource reservation as one …

A QoS enabling queuing scheme for Fourth Generation wireless access networks
… this is achieved by enhancing existing QoS provisioning approaches. The scheme models the radio access network as a network of queuing nodes. With the model, the link layer QoS statistics of user traffic in each available path through the network is determined. The author postulates that …

Mechanisms for quality-of-service provisioning in networks with extended services
… network traffic with various Quality-of-Service (QoS) requirements creates a demand for QoS service provisioning beyond the best effort service that Internet currently provides. QoS provisioning requires a framework that satisfies users' QoS and cost demand while maximizes benefits for network …

Connection admission control and packet scheduling for IEEE 802.16 networks
… support various service types with required QoS characteristics. ... While IEEE 802.16 standard defines medium access control (MAC) and physical (PHY) layers specification, admission control and packet scheduling mechanisms which are important elements of QoS provisioning are left to vendors …

Enhancing end-to-end quality of service provisioning in wireless ad hoc networks using service vectors
… power savings, while enhancing the end-to-end QoS provisioning and granularity in wireless ad hoc networks is proposed in this thesis. Recently, a new concept called service vector has been introduced, which enables an end host to choose different service classes along its data path. This …

Multi-Stream Management for Supporting Multi-Party Three-Dimensional Tele-Immersive Environments
… multi-stream management middleware framework for QoS provisioning to fully enable multi-party 3DTI communication over general delivery infrastructure. The major contributions are as follows. First, we introduce the view model for representing the user interest in the application layer. The design …

Implementation and Performance Evaluation of an NGN prototype using WiMax as an Access Technology
… applications is achieving a Quality of Service (QoS) consistent with user expectations. One of the key additional factors affecting QoS is the existence of different QoS mechanisms on the heterogeneous technologies used on NGN platforms. This research investigates the techniques used to achieve …

Energy-Efficient Self-Organization Protocols for Sensor Networks
… of the most important design goals instead of QoS provisioning and bandwidth efficiency. On the other hand the self-organization ability is essential for the WSN due to the fact that the sensors are randomly deployed and they work unattended. We developed a self-organization protocol, which …

Evaluating the effect of quality of service mechanisms in power-constrained wireless mesh networks
… gone into optimization of Quality of Service (QoS) provisioning in WMN; hence, a lot of QoS mechanisms on OSI layer have been proposed. It is, however, not clear how different QoS mechanisms on OSI layer affect the node lifetime and the energy cost per bit of a battery-powered WMN nodes. …

On characterisation and decomposition of internet traffic dynamics
… traffic classification and Quality of Service (QoS) provisioning. Due to the rapid development of emerging Internet technologies, the expansion of networked devices and evolving user behaviour, the task of statistically interpreting traffic characteristics poses great challenges. There have been …
