User-Centric Energy-Efficient Multimedia Multicast/Broadcast Solutions: A Survey

User-Centric Energy-Efficient Multimedia Multicast/Broadcast Solutions: A Survey

Multimedia multicast/broadcast transmissions provide simultaneous access to a common service to the heterogeneous user equipments (UEs) with different device and channel characteristics. One of the major challenges to the service providers is the exponential growth of energy-constrained UEs. In this context, the optimization of multimedia multicast/broadcast transmissions that consider the cons...

Energy Efficient Multimedia Streaming to Mobile Devices - A Survey

Energy conservation in battery powered mobile devices that perform wireless multimedia streaming has been a significant research problem since last decade. This is because these mobile devices consume a lot of power while receiving, decoding and ultimately, presenting the multimedia content. What makes things worse is the fact that battery technologies have not evolved enough to keep up with th...

Mechanisms Leveraging User Centric Multimedia Convergence

Personalized Energy Priorities: A User-Centric Application for Energy Advice

This research presents a new web-based application, called Personalised Energy Priorities (PEP), that provides households with personalised and tailored advice on practices or technologies they might adopt to improve the energy efficiency of their home. PEP proceeds in a manner similar to an online energy audit, but combines a user centric design approach with relatively new choice modelling so...

Query Log Analysis for User-Centric Multimedia Databases

Recently, the information community has seen the emergence of user-centric media applications, which are characterized by the central position given to the user. To fulfill the user-centric promise, it is necessary to understand and model the actions of the users of the system. This position paper presents a methodology for modeling the behavior of multimedia database users. To this end, we pro...
