Designing heterogeneous bandwidth limited communication systems that support a wide variety of applications, including file transfer, web browsing, interactive games, audio and video calls, and emerging real-time virtual world and social media applications is a challenging task because there is a shortage of resources to satisfy all traffic demands and diverse quality of service (QoS) requireme...

We present an algorithm for reserving compute resources in a Grid, that allows users to define an optimization strategy, if multiple candidates match the specified requirements. Reservations need not to be exact, but can be elastic in some properties like start-, end-time, duration or the number of requested CPUs. Our algorithm takes the speedup of applications into account to accordingly adjus...

This paper presents a new medium access method for a wireless inhouse local area network (LAN). Several existing (draft) standards for wireless communication (e.g. IEEE 802.11, HIPERLAN or Magic WAND) cannot full ll quality of service demands for typical inhouse applications (e.g. video, audio, phone and computer) or they set up the need for a central hub. We show that quality of service demand...

In designing a video broadcasting system, the delay preference of a user is traditionally regarded as unknown. In fact, such preference can be known upon user’s arrival by employing some techniques such as i) delay-dependent charging, where users are offered different levels of pay-per-view (PPV) depending on the maximum delay they are willing to tolerate; or ii) reservation, where a user speci...
