An Event-driven Service-oriented Architecture for Internet of Things Service Execution

IoT (Internet of Things) fuses the physical world and information space. The features of IoT services are different from the traditional Internet services, such as environmental sensitive, event driven, service coordination, complex presentation. The new IoT service architecture should adapt to these features. This paper analyses IoT sensing service characteristics and proposes the future services architecture. It mainly discusses the application layer architecture and the interface presentation technology evolution. In application layer, the traditional SOA architecture is insufficient in the real-time response and parallelism process of services execution, this paper proposes that the new sensing service system architecture may be dominated by EDSOA (Event Driven SOA) architecture to support real-time, concurrency event driven active services execution. At presentation layer, this paper presents the new IoT browser features including using augmented reality technology to input and output, and realize the superposition presentation of the physical world and abstract information. Through a practical application system case - road manhole covers monitoring system to verify the feasibility of the proposed ideas and frameworks.
