Adaptive Middleware Services for Situation-Aware Communication in
Ubiquitous Computing Environments (NSF-funded)
Our goal is to integrate context-awareness and ad hoc group communication to
provide a sufficient basis for a new breed of collaborative ubiquitous
computing applications. In a Ubiquitous Computing (Ubicomp) environment, users carry wearable, and
handheld devices, which are connected over wireless networks. The
interaction pattern among the devices is dependent upon the social context
of the users. In other words, the role of a social group should be mapped to
a community of devices (device group), which can support the collaboration
among the members of the social group. We have proposed a model to address
this mapping and how device group should aid users in group collaboration.
Based on the model, we developed a distributed context-aware group
membership scheme and a distributed group view maintenance protocol. We also
implemented a test bed over WinCE on PDAs to demonstrate our approach, along
with several Smart Classroom applications, which are currently using in
CSE461, CSE462 class at Arizona State University. The experiment results
demonstrate the feasibility of our system.
Currently, we are evaluating our system through usability test.
