The use of Sensor Networks to create smart environments

Internet of Things is taking the world in order to be the next big thing since the Internet, with almost every object being connected to gather data and allow control through mobile and web devices. But this revolution has some barriers with the lack of standardization in communications or sensors. In this dissertation we present a proposal of a system dedicated to creating smart environments using sensor networks, with a practical application developed to achieve automation, efficiency and versatility, allowing real-time monitoring and remote control of any object or environment improving user experience, tasks efficiency and leading to costs reduction. The developed system, that includes software and hardware, is based on adaptive and Artificial Intelligence algorithms and low cost IoT devices, taking advantage of the best communication protocols, allowing the developed system to be suited and easily adapted to any specification by any person. We evaluate the best communication and devices for the desired implementa tion and demonstrate how to create all the network nodes, including the build of a custom IoT Gateway and Sensor Node. We also demonstrate the efficiency of the developed system in real case scenarios. The main contributions of our study are the design and implementation of a novel architecture for adaptive IoT projects focus on environment efficiency, with practical demonstration, as well as comparison study for the best suited communication protocols for low cost IoT devices.A Internet of Things está a atingir o mundo de modo a tornar-se a próxima grande revolução depois da Internet, com quase todos os objectos a estarem ligados para recolher dados e permitir o controlo através de dispositivos móveis.

Unified radio and network control across heterogeneous hardware platforms

Experimentation is an important step in the investigation of techniques for handling spectrum scarcity or the development of new waveforms in future wireless networks. However, it is impractical and not cost effective to construct custom platforms for each future network scenario to be investigated. This problem is addressed by defining Unified Programming Interfaces that allow common access to several platforms for experimentation-based prototyping, research, and development purposes. The design of these interfaces is driven by a diverse set of scenarios that capture the functionality relevant to future network implementations while trying to keep them as generic as possible. Herein, the definition of this set of scenarios is presented as well as the architecture for supporting experimentation-based wireless research over multiple hardware platforms. The proposed architecture for experimentation incorporates both local and global unified interfaces to control any aspect of a wireless system while being completely agnostic to the actual technology incorporated. Control is feasible from the low-level features of individual radios to the entire network stack, including hierarchical control combinations. A testbed to enable the use of the above architecture is utilized that uses a backbone network in order to be able to extract measurements and observe the overall behaviour of the system under test without imposing further communication overhead to the actual experiment. Based on the aforementioned architecture, a system is proposed that is able to support the advancement of intelligent techniques for future networks through experimentation while decoupling promising algorithms and techniques from the capabilities of a specific hardware platform
