Keynote Talk I
IMS Services and Their Extensions to Ad-Hoc Systems, by Jason Lin
IP Multimedia Core Network Subsystem (IMS) integrates mobile telecommunications with Internet. As IMS
evolves, more new call control features are supported to accommodate the advantages of Internet. On the other hand, IMS extension to ad-hoc applications is seldom
mentioned in the literature. In August 2009, Typhoon Morakot seriously damaged the mobile base stations in south Taiwan, and IMS infrastructure mode did not work. We
learned a painful way that ad-hoc mode for IMS is urgently needed in such events. This talk investigates three IMS call applications relate to telecommunications needed in
a nature disaster: emergency call, Push-to-talk over Cellular (PoC), and Voice Call Continuity (VCC). We describe the performance issues of these IMS applications in
infrastructure mode, and then discuss the research issues for extending them to ad-hoc systems.

Keynote Talk II
From Wireless Networking to Smart Computing: Challenges and Solutions, by Sajal K. Das
The last decade has seen tremendous advancements in computer science and engineering such as wireless
networks, mobile and pervasive computing, information mining, ambient intelligence, human-centered computing, middleware, and so on. These technologies have made the world
closer and our life experience better than ever as we live in an increasingly connected and automated society that links devices, computing and communication platforms to
everyday tasks and settings. As a result, recently there has been an upsurge of multi-disciplinary research projects on the design and development of smart environments.
We define a "smart environment" as one that is able to autonomously acquire and apply knowledge about a sensor-driven environment, and adapt to user preferences
to improve their experience without explicit awareness.
In this talk, we will first give a brief overview of emerging research directions in wireless mobile,
sensor and pervasive networks, and then discuss fundamental challenges and issues in design and modeling of smart environments. We will also present novel frameworks and
algorithmic solutions for tracking user contexts (e.g., activity, location) as captured by sensors while users interact with the environment on a daily basis, thus leading
to intelligence automation, autonomic and context-aware computing. The underlying approaches will be based on information theory, text compression, on-line learning,
uncertainty reasoning, and game theory. The proposed models will be validated with the help of agent based architecture and tools that we developed. A video demo will also
be shown. The talk will be concluded with open research problems and future directions in this field.
