Definition

AutonomicBeing accomplished without overt thought and action.

ex. the human autonomic nervous system that monitors and regulates temperature, pupil dilation, respiration, heart rate, digestion, etc.

Autonomic computingAn approach to self-managed computing systems with a minimum of human interference.

Narration: 철수 아버지의 심장에 부착된 센서가 u-PDA, u-홈서버에 긴급 상황임을 알린다. 긴급 상황임을 주치의에게 알리고, 병원으로 옮기기 위한 서비스 목적을 자동으로 생성하여 이를 실행하기 위한 커뮤니티를 자동 생성한다. (의사 EMR, 병원정보 시스템, 철수 아버지 심장 센서, 철수 PDA…)

Conclusion

Mobile Community Computing is very effective …

- to realize autonomous computing environment.- to improve productivity for development and provisioning of ubiquitous services.

- to create new service using existing devices/services/infra. - to meet the demands of time-critical events providing just-in-time service through situation awareness.

- …

Next research challenges is …

- to generate goal and configure community dynamically.- to expand into agent-based distributed model.- to design situation awareness using ontology.- to design high level policy-based execution.- …
