IPTV is defined as multimedia services, such as TV, video, audio, text, graphics, and data, delivered over IP-based networks managed to support quality of service (QoS), quality of experience, security, interactivity, and reliability. Mobile IPTV extends those services to mobile networks. The authors discuss mobile IPTV standardization's status, related approaches in the field, and technical challenges...
This paper discusses the inter-layer mobility and quality of service (QoS) support in a multi-tier Wireless Overlay Network (WON). It proposes integrated network architecture with layer manager for vertical handoff, switching and mobility management using Mobile IP protocol. Various functionalities of the Layer manager are implemented as modular blocks and are distributive over the gateways in each...
The wireless network landscape is changing gradually from homogeneous to heterogeneous and future generation networks are envisioned to be a combination of diverse but complimentary access technologies, like GPRS, WCDMA/HSPA, LTE, WiMAX, and WLAN. One issue which has become apparent recently with the proliferation of different link layer technologies is how service providers can offer a consistent...
A network based method for an intelligent distribution of transport resources of heterogeneous points of attachment to the network among mobile nodes with multiple network interfaces is presented in this paper. Selection of the used network for a particular multimedia session is based on the QoS situation in access networks available for mobile nodes. A possible realisation using IP multimedia subsystem...
