ABSTRACT Taking into account the increase of the real estate development and the construction of smart cities, the control and interoperability between the devices in the smart home environment has become an interesting topic for further research. The aim of this paper is to present the convergence of smart home into the cloud computing using different network protocols. Moreover, the ways that smart homes can facilitate the development and integration with cloud computing is further discussed and analysed.

ABSTRACT Data and Internet services have become ubiquitous, and the recent trend of building massive cloud datacenters is part of the current network evolution. The success of Internet of Things (IoT) will not so much depend on the development of new technologies, but rather on connecting and integrating existing resources. The paper proposes a novel architecture that enables objects to exchange information through the Internet to achieve nonintrusive behavior and customized services based on an open source cloud platform. To achieve this goal, the information driven interactions are done not only in a peer to peer method, but also via advanced cloud services. The result is a generic platform where devices, systems and services will take part in a heterogeneous and decentralized architecture. We demonstrate that IoT is all about interoperability, from connected cloud computing using RFID, NFC, M2M and sensor technology to digital content and context-aware services. We conclude our cloud of things vision by expanding on the need for interoperability of cloud and IoT.

A plethora of digital ECG formats have been proposed and implemented. This heterogeneity hinders the design and development of interoperable systems and entails critical integration issues for the healthcare information systems. This paper aims at performing a comprehensive overview on the current state of affairs of the interoperable exchange of digital ECG signals. This includes 1) a review on existing

One of the challenges of evolving healthcare information systems used in healthcare domain is their interoperability. Interoperability not only permits healthcare institutes to take advantage of using heterogeneous solutions from different vendors but it also offers the basis for creating a larger range of services at the edge of medicine/healthcare and information technology. New services can be created in a consistent way based on common approaches of structuring and representing healthcare data. This paper presents a test framework for testing interoperability of eHealth systems. As a major result, the test framework is designed for test automation and extendability with respect to test configurations and test cases.

Most organizations require the verification of personal information before providing services, and the privacy of such information is of growing concern. The authors show how federated identity management systems can better protect users' information when integrated with trust negotiation. In today's increasingly competitive business environment, more and more leading organizations are building Web-based infrastructures to gain the strategic advantages of collaborative networking. However, to facilitate collaboration and fully exploit such infrastructures, organizations must identify each user in the collaborative network as well as the resources each user is authorized to access. User identification and access control must be carried out so as to maximize user convenience and privacy without increasing organizations1 operational costs. A federation can serve as the basic context for determining suitable solutions to this issue. A federation is a set of organizations that establish trust relationships with respect to the identity information-the federated identity information-that is considered valid. A federated identity management system (idM) provides a group of organizations that collaborate with mechanisms for managing and gaining access to user identity information and other resources across organizational boundaries
