Abstract

Currently, people in IT field have found new research target to explore new era, which is called Ubiquitous computing. With this new target, the main objectives are not simply returning accurate and fast results or small size of devices which are requirements in conventional computing environments but providing the convenient and stable services to humans with considering the surrounding or environment of object such as humans or devices. For showing direction of Ubiquitous computing, this paper proposes 5 key scopes which are researched and pursued importantly. They are Interface, Security and Privacy, Processing, Communication, and Sensing. Also, this paper suggests ACCM (Autonomic Community Computing Model) as a metaphor of collaboration and coordination model among devices and services in ubiquitous computing environment. Based on the ACCM, devices and services are organized as a community to enable more various and complex services and developer can make a service by specifying, organizing, or reusing a community. In this paper, we describe basic concepts and technical issues of ACCM and propose a system framework which satisfies the requirements in ACCM.
