Living Interactively and Socializing Ubiquitously

This keynote talk will address the psychology of living in a ubiquitous computing environment, by focusing on how new technological affordances enable individuals to express agency and build community in an ongoing manner. The recent proliferation of location-based information tools and the popularity of communication technologies that encourage social interaction have contributed to a computationally intensive environment, with users constantly managing information for themselves as well as sharing information with others at unprecedented levels. We constantly straddle real and virtual worlds without making the distinction between the real and the virtual. We have come to expect high-fidelity, context-aware systems that serve to blur the boundary between the two. As a result, rules of interaction management are undergoing dramatic changes, with consequences for design of future systems and interfaces.

Next Generation Network, Wireless Network and Topology Control with Small Routing Cost

One of important components in the potential next generation network is the wireless network. Topology control is one vital factor to a wireless networkЎЇs efficiency. Since wireless network has no physical infrastructure, it may lead to a severe problem, known as broadcast storm problem caused by flooding inherent in on-demand routing schemes. Inspired by physical backbone in classical wired networks, the virtual backbone has been proposed and studied extensively in the literature for wireless networks to reduce the damage caused by flooding and to maximize resource utilization. However, when we employ the virtual backbone, two problems may be introduced. The first one is the increasing of routing cost. The second one is that the road load on some links may increase, which may cause traffic jam. How do we solve those problems. In this talk, we will introduce recent research work on their solutions.
