A Case Study of Service-Centric IoT Model for Rural Sewage Disposal

The Internet of Things (IoT) refers to an emerging paradigm, to seamlessly and ubiquitously integrate a large number of smart things with intra/inter links to the physical and cyber worlds. The sensor enabled communication technologies are connecting billions of things, by efficiently utilizing their locations in the real world. However, how to use a reasonable architecture to build IoT services via heterogeneous and distributed smart things and sensors is an important and challenging issue, especially in rural areas where power and network resources are relatively scarce. In this work, to catch the challenge, we propose an Integrated IoT service model for distributed sensors. By modeling sensors into information resources, a RESTful service model is applied to each sensor. By using IoT based service adapter, information resources are integrated into service center which is feasible be accessed by electrical power and wireless network. A case study of rural sewage disposal is conducted based on the proposed service model. Also, a developed prototype system of rural sewage disposal shows the feasibility and effectiveness of the proposed model.
