Currently, the main care model for supporting elderly people living alone at home is based on informal and formal caregivers assistance. Considering the demographic changes of older population, which increases rapidly, ...

As currently specified by 3GPP for UMTS, MBMS services are provided within a cell, either by P-t-P or by P-t-M transmission mode, but not both at the same time. Our previous work highlighted the inefficiencies that can ...

This work, using a game-theoretic approach, considers Internet-based computations, where a master processor assigns, over the Internet, a computational task to a set of untrusted worker processors, and collects their ...

We consider Internet-based Master-Worker task computing systems, such as SETI@home, where a master sends tasks to potentially unreliable workers, and the workers execute and report back the result. We model such computations ...

This work considers Internet-based task computations in which a master process assigns tasks, over the Internet, to rational workers and collect their responses. The objective is for the master to obtain the correct task ...

Computing the visibility of out-door scenes is often much harder than of in-door scenes. The difficulty is that although the majority of objects are hidden, some parts might be visible at a distance in an arbitrary location, ...

With the introduction of Multimedia Broadcast Multicast Service (MBMS) in 3rd Generation (3G) Networks, the Radio Network Controller (RNC) for radio efficiency reasons can use either Dedicated or Common resources to ...

Handover Control in a cellular infrastructure aims to provide continuity of mobile services to a user traveling over cell boundaries. So far, Handover Control is considered only between cells supporting the service using ...

Handover Control in a cellular infrastructure aims to provide continuity of mobile services to a user traveling over cell boundaries. Using the existing Handover Control algorithm in 3rd Generation (3G) Mobile Cellular ...
