Using A-Federations for On-Demand Crisis Situation Response

摘要

Dynamic, service-based systems offer powerful resources for knowledge and information processing in a crisis situation. These systems need efficient strategies to integrate diverse services under the stress of an emergency to capture, organize, and disseminate appropriate information. These strategies require a combination of service discovery, 'mashing', and orchestration given workflow task templates that can be instantiated and deployed on demand. In this paper, we introduce the A-Federation reference architecture for on-demand emergency management systems (ODEMS). The A-Federation provides the foundation for incorporating these strategies that consider type, availability, and requirements of services as historically understood by users in similar crisis events.
