First Speaker: Dr. Tom Van Cutsem, Vrije Universiteit Brussel
Title: Ambient-oriented Programming & Ambient Talk
Abstract:
Summarize our research on ambient-oriented programming of the past four years.
Biography:
I’m a post-doctoral computer science researcher at the Software Languages Lab of the Vrije Universiteit Brussel, funded by the Flanders Research Foundation. I have recently finished my doctoral thesis on advanced programming language support for mobile ad hoc networks. I am co-designer of the Ambient Talk programming language.

Second Speaker: Susumu Toriumi, The University of Tokyo
Title: XAC Project and Sensor-Task Assignment
Abstract:
To maximize utilization of Wireless Sensor Networks (WSN) under severe resource constraints poses several difficulties for WSN users ranging from the algorithmic domain to the software engineering domain. To hide such difficulties from users, XAC project introduces middleware layer; thus users don’t have to consider several low-layer details.
In this presentation, We introduce the project itself briefly followed by the specific problem, Sensor-Task Assignment Problem. In this problem setting, we consider reactive WSNs processing queries, which describe Tasks. For each task, the appropriate set of sensors must be selected so as to minimize energy while ensuring QoS constraints.
Previous and novel formalizations with solution approach are presented. We also address possible integration with the middleware.
Biography:
Susumu Toriumi (storiumi@nii.ac.jp) is a master course student at Department of Computer Science, the University of Tokyo, Japan. He is also a member of XAC project and worked in the field of wireless sensor networks. He received a degree in information science (BSc) from the University of Tokyo in 2008.
