A DSM for a Modeling RESTful Sensor Web Network

Entering the era of Internet of Things, the use of Wireless Sensor Network and Sensor Web elements becomes a daily phenomenon. Information systems which must ensure that an increasing number of devices access and analyze the data collected from the wireless sensor nodes, have become complex and difficult to maintain. Due to the discrete nature of computer based systems, where the relationship between action and response may not be proportional, there is a huge risk when control is concerned. Design of unique sensor network that will meet the imposed needs sometimes is a serious task usually involving experts from different areas of the problem, design and implementation domains. On the other hand the introduction of novel technologies and techniques, like DomainSpecific Modeling and RESTful service technology, in sensor networks design, raises the importance of problem domain. The involvement of such a wide variety of stakeholders, together with the nature of computer based systems and the constantly changing methods and technologies, sometimes leads to overall project failure mainly because of the lack of a mutually agreed high level domain specific model. In this paper, the specification of meta-model for RESTful Sensor Web Network modeling together with accompanying language editor, are described. The verification and validation of its functionality is performed based on suitable examples of sensor network design models.
