The Internet of Things (IoT) has emerged as a paradigm in which smart things actively collaborate among them and with other physical and virtual objects available in the Web in order to perform high-level tasks. IoT environments are typically characterized by a high degree of heterogeneity, thus encompassing devices with different capabilities, functionalities, and network protocols.

The Internet of Things (IoT) has emerged as a paradigm in which smart things actively collaborate among them and with other physical and virtual objects available in the Web in order to perform high-level tasks. IoT environments are typically characterized by a high degree of heterogeneity, thus encompassing devices with different capabilities, functionalities, and network protocols. In such a scenario, it is necessary to provide abstractions for physical devices and services to applications and end-users, as well as means to manage the interoperability between such heterogeneous elements. In this context, we introduce EcoDiF (Web Ecosystem of Physical Devices), a Web-based platform for integrating heterogeneous physical devices with applications and users in order to provide services to support real-time data control, visualization, processing, and storage. In this paper, we present the main features of EcoDiF and detail its architecture and implementation, which is based on well-known Web technologies such as HTTP, REST, EEML, and EMML. Furthermore, we present a preliminary evaluation of an EcoDiF prototype through proof-of-concept applications from different domains as well as a performance analysis of the platform. Exibir menos

In the near future, it will be possible that every object on Earth can be identifiable and addressable. Such objects will be able to be monitored and monitor their physical environments, and of executing actions on such environments in benefit of human users. Moreover, these so-called smart objects will be endowed with wireless communication capabilities. By being uniquely addressed, wireless endowed and through the use of existing protocols and standardized formats, smart things can be… Exibir mais

In the near future, it will be possible that every object on Earth can be identifiable and addressable. Such objects will be able to be monitored and monitor their physical environments, and of executing actions on such environments in benefit of human users. Moreover, these so-called smart objects will be endowed with wireless communication capabilities. By being uniquely addressed, wireless endowed and through the use of existing protocols and standardized formats, smart things can be integrated in the Internet and accessed as any other Web resource. In this context, the Internet of Things (IoT) emerges as a paradigm in which smart things actively collaborate among them and with other physical and virtual objects available in the Web, providing value-added information and functionalities for users. The IoT paradigm has recently showed its potential of considerably impacting the daily lives of human beings mainly due to the use and interaction of physical devices in several domains, including complex systems composed of other systems. In this paper we discuss the IoT paradigm from the perspective of Systems-of-Systems and present EcoDiF, a IoT platform that integrates heterogeneous devices to provide real-time data control, visualization, processing, and storage. In EcoDiF, devices, information, users and applications are integrated to create an IoT ecosystem in which new ideas and products can be developed in an organic way. Exibir menos
