The state of many physical, biological and socio-technical systems evolves by combining smooth local transitions abrupt resetting events to a set reference values. inclusion the mechanism not only provides possibility modeling wide variety realistic but also leads interesting novel phenomenology present in reset-free cases. However, most models where stochastic is studied address case finite nu...

The systems and networking community lays great store by“simple” system designs. Yet, our rationalization about whether a system meets this goal often relies more on intuition and qualitative discussion than rigorous quantitative metrics. In this paper, we develop a prototype metric that seeks to quantify this notion of complexity with regard to the algorithmic component of a networked system d...

When a networked virtual reality system handles composite media audio and video as well as three dimensional computer graphics, the quality of the virtual space is also greatly affected by the currently available network and end system resources. In this paper, we discuss the architecture of a networked virtual reality system C3. We propose a new criterion called IoP(Importance of presence) for...

The emergence of handheld devices associated with wireless technologies has introduced new challenges for middleware. First, mobility is becoming a key characteristic; mobile devices may move around different areas and have to interact with different types of networks and services, and may be exposed to new communication paradigms. Second, the increasing number and diversity of devices, as in p...

We live in a networked age. Always-on technology now links people together in a myriad of ways that was inconceivable just a few decades The social impact of these technologies – especially over the last twenty years or so – has been massive. Networking has changed the ways we communicate, how we write, how we stay in touch with friends, how we conduct our day to day affairs, and even how we at...
