   Sensor networks, and more specifically wireless sensor networks (WSN), are generally used to collect information from the environment. The gathered data are mainly delivered to sinks or gateways that become the endpoints where applications can retrieve and use such data. But applications would also expect from a WSN an event-driven operational model, so that they can be notified whenever occur some specific environmental changes instead of analyzing continuously the data provided periodically.In either operational model, wireless sensor networks represent a collection of objects interconnected, in a similar way that is outlined by the Internet of Things vision. In following years sensors will become more capable and resourceful. But in the meantime, they lie into the definition of constrained devices. In addition, to fulfill the vision of the Internet of Things, they must have a virtual representation that allows indirect access to their resources, a model that should also include the virtualization of event sources in a WSN.Thus, in this paper we propose a model for a virtual representation of event sources in a WSN. The event sources are modeled as internet resources that are accessible by any internet application, following an Internet of Things approach. The model has been tested in a real implementation where a wireless sensor network has been deployed in an open neighborhood environment. Different event sources have been identified in the proposed scenario, and they have been represented following the proposed model.

   Wireless Sensor Networks (WSNs) are generally used to collect information from the environment. The gathered data are delivered mainly to sinks or gateways that become the endpoints where applications can retrieve and process such data. However, applications would also expect from a WSN an event-driven operational model, so that they can be notified whenever occur some specific environmental changes instead of continuously analyzing the data provided periodically. In either operational model, WSNs represent a collection of interconnected objects, as outlined by the Internet of Things. Additionally, in order to fulfill the Internet of Things principles, Wireless Sensor Networks must have a virtual representation that allows indirect access to their resources, a model that should also include the virtualization of event sources in a WSN. Thus, in this paper a model for a virtual representation of event sources in a WSN is proposed. They are modeled as internet resources that are accessible by any internet application, following an Internet of Things approach. The model has been tested in a real implementation where a WSN has been deployed in an open neighborhood environment. Different event sources have been identified in the proposed scenario, and they have been represented following the proposed model.

   Néstor Lucas Martínez received the highest qualification, “Matrícula de Honor”, for his Bachelor Thesis.

   The increasing of the capabilities of all kind of devices is causing a revolution in the field of the provision of services, both in quantity and in diversity. This situation has highlighted the need to address unprecedented technological development, where the forecast of interconnected and interoperable devices between them and human beings reaches the order of billions. And these numbers go further when the connectivity of constrained networks is taken into account. This idea of an interconnected world of things has led to a vision that has been called "The Internet of Things". It’s a vision of a world where things of any kind can interact with other things, even those in the domain of a constrained network. This also leads to the creation of new composed services that exceed the sum of the parts. Besides the technological interest, this new vision relates with the one from the Smart City. A concept that uses the convergence of the energy, the transport, and the information and communication technologies to define a way to achieve sustainable and competitive growth, improving the quality of life, and opening the governance of the cities to the participation. In the development pathway to reach these goals, this Final Degree Dissertation proposes a way for the virtualization of the services offered by the variety of devices that are reaching the ability to interoperate in a network. For this it is supported by a service oriented middleware called nSOM that has been developed at EUITT. Using this architecture the goals proposed for this project are the design and development of a service gateway that makes available the resources of a sensor network through a web interface; the design and development of a Device & Service Registry according to the reference architecture proposal for the Internet of Things; and the study and design of a composition framework for orchestrated services in constrained networks. To achieve these goals this dissertation begins with a State of the Art study where the background knowledge about the technologies in use for the interoperation of things will be settled. At first it starts talking about Wireless Sensor and Actuator Networks, the architectures for Machine-to-Machine communication and Internet of Things, and also the concepts for the Web of Things vision. Next the related network and services technologies are explored, ending with a brief review of service composition technologies. Then will follow a detailed description of the nSOM architecture, and also of the proposed design for this project. Finally a scenario will be proposed where a series of validation tests will be conducted.
