Abstract: Recently, there has been an increase in devices and applications for smart homes. This led to the creation of solutions that facilitate the interconnection of all these components, providing fully transparent solutions to the user. This abstraction layer defines the concept of middleware. Besides this problem of heterogeneity, it's also toconsider increasing the usability provided, increasing the user's convenience. Due to major technological developments, specifically in the area of multifunctional mobile devices, it is not unthinkable to imagine the migration of this type of middleware in such equipment as it will provide users with an excellent integration of multiple services under a stunning user interface. In addition to this migration, the use of sensory capabilities of these devices can improve and innovate the way the user interacts with his own home.

The end result of this work allows all operations, that were carried out until now in static devices, ie computers or presence detection methods through code or RFID, are performed on smartphones from Apple.

With the tests' results, it can be concluded that the performance of the equipment is good. In terms of usability, it was found that this solution introduces a significant improvement in the interaction with the house by users.

Abstract: During the last few years, continuous progress in wireless communications have opened new research fields in computer networking, aimed at extending data networks connectivity to environments where wired solutions are impracticable. Among these, vehicular networks are attracting a growing attention from both academia and industry, due to the amount of related applications and their importance, ranging from road safety to traffic control, up to mobile entertainment. Vehicular Ad-hoc NETworks (VANET) are self-organized networks built up from moving vehicles, and are part of the broader

class of Mobile Ad-hoc NETworks (MANET). Due to the prohibitive cost of deploying and implementing such a system in the real world, most research in VANET relies on simulations for evaluation. To help us perform a VANET simulation, we currently have traffic, network and VANET simulators. The traffic simulator is the one responsible for generating the nodes mobility, the mobility pattern (which is the biggest challenge in conducting VANET simulations), that is then fed to the network simulator to conduct the simulation itself. When we combine these two distinct simulators we create a full VANET simulator. Simulation is the most widely adopted solution to make a good design but it also presents an important challenge: the fidelity of the simulation compared to real world results. This dissertation presents a study and a comparison among these simulators, and a definition of an architecture in order to evaluate the most realistic solution available.

Key Words: VANET, traffic simulators, network simulators, MObility model generator for VEhicular networks (MOVE), Network Simulator 2 (NS-2) and Network Simulator 3 (NS-3).


Sistema de interacção com TV e sensores para apoio doméstico

Candidato: Nº 66722 Carlos Miguel de Jesus Rodrigues

Presidente: Professor Rui Jorge Morais Tomaz Valadas

Orientador: Professor Rui Manuel Rodrigues Rocha

Abstract: Wireless Sensor Networks have enormous potential for application. In domestic environments may allow a variety of applications such as home monitoring and control, energy management at home, health care, among others. Current solutions that make use of this technology usually only focus on one type of application and not leverage the infrastructure of the telecommunications operator. ZON Multimedia, in conjunction with Link Consulting, identified this area as one that would require research to develop a range of new services in order to increase customer retention.

This dissertation aimed to develop an architecture that considers the integration of a sensor network in the ZON Multimedia home gateway solution to control home systems.
