Internet of Things is an emerging area and it visions an inter-connected world full of physical as well as virtual objects, devices, processes and services capable of providing a different lens on how to link them via the Internet. While Internet of Things as part of the Future Internet has been described as a paradigm that mainly integrates and enables several technologies and communication solutions a notable interest is to define how current standard communication protocols could support the realization of the vision. Within this context, we offer a state-of-the-art review on ad hoc and wireless sensor networks, near field communications, radio frequency identification and routing protocols as a mean to describe their applicability towards an Internet of Things realization. We conclude by presenting a brief case scenario to describe a future smart environment and illustrate its possible model architecture.

In this project, we explore two forms of user authentication, alternative to the alpha-numeric password, through utilization of various hardware components in a modern smartphone. These components act as input channels for biometric and geolocative data, which can be used to validate the identity of a user through gesture-based authentication (via the accelerometer and orientation sensor) and locationbased authentication (via the WIFI sensor). We develop an Android application that incorporates these two authentication methods. We implement two different gesture-based authentication algorithms adapted from existing work done in this field of security research. We find that one algorithm is more convenient to train and implement than the other algorithm, but also performs more poorly in terms of accuracy compared to the other algorithm. We also implement a location-based authentication algorithm based on scanning the WIFI access points around the user’s current location. We introduce thresholds into the algorithm to provide tolerance and robustness against inconsistent WIFI access points, and these thresholds show improvement in the algorithm’s performance.

I present my work towards learning a better computer vision system that learns and generalizes object categories better, and behaves in ways closer to what human behave. Speci cally, I focus on two key components of such a system: learning better features, and revisiting existing problem statements. For the rst component, I propose and analyze novel receptive eld learning and dictionary learning methods, mathematically justi ed by the Nystrom sampling theory, that learn more compact and e ective features for object recognition tasks. For the second component, I propose to combine otherwise independently developed computer vision and cognitive science studies, and present the rst large-scale system that allows computers to learn and generalize closer to what a human learner will do. I also provide a large-scale human behavior database, which will hopefully enable further research along this research direction.
