Improving IPTV Forwarding Mechanism in IEEE 802.16j MMR Networks Based on Aggregation

Abstract

Internet protocol television (IPTV) service depends on the network quality of service (QoS) and bandwidth of the broadband service provider. IEEE 802.16j mobile multihop relay Worldwide Interoperability for Microwave Access networks have the opportunity to offer high bandwidth capacity by introducing relay stations. However, to actually satisfy QoS requirements for offering IPTV services (HDTV, SDTV, Web TV, and mobile TV) for heterogeneous users' requests, providers must use a video server for each IPTV service type, which increases the network load, especially bandwidth consumption and forwarding time. In this paper, we present a solution for forwarding IPTV video streaming to diverse subscribers via an 802.16j broadband wireless access network. In particular, we propose a new multicast tree construction and aggregation mechanism based on the unique property of prime numbers. Performance evaluation results show that the proposed scheme reduces both bandwidth consumption and forwarding time.

A combined path selection and admission control scheme for IPTV in IEEE 802.16j MMR networks

“…In packet scheduling, Call Admission Control (CAC) is a very important element in the WiMAX network, since it is supposed to provide a Quality of Service (QoS) guarantees [2]. Without an effective CAC, IEEE 802.16j standard will not be able to provide guaranteed QoS for realtime applications such as audio and video [3].…”

Symbiotic Dynamic Memory Balancing for Virtual Machines in Smart TV Systems

“…This trend shows that the TV has been transformed from a home appliance handling only broadcast media, to a full technology system that provides other valuable services, such as web browsing, online gaming, video streaming, and other Internet-based content [1]. Since then, major manufacturers, such as Samsung, LG, and Sony, have invested in the development of Smart TV products.…”

“…Since then, major manufacturers, such as Samsung, LG, and Sony, have invested in the development of Smart TV products. This trend shows that the TV has been transformed from a home appliance handling only broadcast media, to a full technology system that provides other valuable services, such as web browsing, online gaming, video streaming, and other Internet-based content [1]. Due to the paradigm shift toward the TV becoming a softwarecentric system, we expect that next-generation Smart TV systems will become ubiquitous in home environments by introducing cloud services based on virtualization technologies [2]- [3].…”
