The W3C Web of Things (WoT) architecture is a model for handling Things (i.e. We proved the concept of the architecture by implementing a prototype platform with an vacant room detection application. We also design a cloud platform on which IoTMaaS be executed in harmony with stakeholders such as end users, device manufacturers, and cloud computing providers.

In this paper, we propose a cloud-based IoT mashup service model, called IoT Mashup as a Service (IoTMaaS), to overcome heterogeneity of devices by following the model driven architecture principles and computational scalability based on cloud computing paradigm. However, this approach may have limitations in dealing with many heterogeneous devices and computation scalability in the presence of large number of things involved. Many recent researches suggest that mashup in IoT environment is possible with existing web mashup technology if each thing exposes its functionalities as a web service. Mashup, a way to compose a new service from existing services, is expected to play a great role in internet of things (IoT) environment. This has a positive impact on the way WoT applications are Web services and Things) that co-exist and interact with each other Least, OpenAPI achieves uniformity of representation of both types ofWoT entities The approach is a mechanism that facilitates the generation of OpenAPI Thingĭescriptions and a Web proxy that implements access to Things on the Web.Īn implementation of the API is also proposed and evaluated. Therefore, it is more mature and can become acceptable. Standard endorsed by prominent industry vendors and user communities. OpenAPI is already a widely accepted industry Leveraging the latest results on hypermediaĬonstruction and documentation of RESTful APIs, we argue that OpenAPIĬan also be used to provide documentation of Things that adheres to the W3CĪrchitecture recommendation. Representation of Things based on JSON-LD and RESTful API interfaces
