Wireless networks have been evolved to heterogeneous overlay structure, in which various wireless technologies provide partial or full coverage of the service area. Another evolution direction is multi-service wireless networks. In multi-service networks, traffic of various QoS classes is serviced concurrently. In this paper, we propose a scalable and flexible network selection scheme for multi-service...
Admission control (AC) is an important feature in a wireless network by which radio resource usage is optimized whilst maintaining the Quality of Service (QoS) of existing users. In this paper, a novel admission control mechanism is proposed for the Long-Term Evolution (LTE) cellular networks. Simulation results show that the proposed AC can provide a more flexible trade-off between network and user...
The purpose of this study is to guarantee Quality of Service (QoS) in wireless multi-hop networks by introducing an admission control scheme. In wireless single-hop networks, IEEE 802.11e Enhanced Distributed Channel Access (EDCA) is the standard for QoS control. However, to control QoS, it is necessary to modify the currently used IEEE 802.11 Distributed Coordination Function (DCF)-compliant terminals...
Enabling end-to-end quality of service (QoS) for realtime video content delivery across heterogeneous P2P networks is challenging but vital for the efficient service provision. In this paper, we present a P2P based admission control mechanism for real-time video streaming driven by service provider (SP). SP- driven P2P network is a network where service provider has a comprehensive control over contracted...
In this paper, we present an admission control mechanism for video streaming driven by service provider (SP) over P2P networks. SP-driven P2P network is a network in which service provider has a comprehensive control over contracted resources utilisation. SP assures the coordination and the creation of overlay P2P network and it is responsible for admission control and resource allocation among others...
