Ubiquitous Air Quality Monitoring System With Service Oriented Architecture Middleware
The authors have been developing AirScope, an event-based air quality monitoring system, since 2008 and regularly add new features to it. The first version of AirScope is up and running on desktop and mobile platforms; however, it is limited in its capability to assimilate new sensors and components from other parties. In order to add third party components, extensive manual integration is required. In this paper, they propose using Enterprise Service Bus (ESB) as AirScope's data communication and exchange channel. ESB is a centralized, logical, architectural component that operates in a distributed, heterogeneous environment to facilitate the requirements of a highly scalable, fault-tolerant, service-messaging framework.
