This book deepens the understanding of people through smartphone data obtained via mobile sensing and applies psychological insights for social networking applications. The author first introduces TYDR, an application for researching smartphone data and user personality. A novel, structured privacy model for mobile sensing applications is developed and the obtained empirical results help researchers gauge what data they can expect users to share in daily-life studies. The new research findings, the concept of mobile sensing, and psychological insights about the formation and structure of real-life social networks are integrated into the field of social networking. Finally, for this novel integration, the author presents concepts, decentralized software architectures, and fully realized prototypes that recommend new contacts, media, and locations to individual users and groups of users.

This thesis focuses on the design and use of software defined networking (SDN) in residential Internet service providers (ISPs), as well as innovative operational models that can be incorporated in broadband ecosystems. Though SDN addresses the challenges for bundled best-effort service provided by broadband operators for users, it does not distinguish between the different types of applications (video streaming, web-browsing, and large file transfers), nor does it cater to the varying needs of different household devices (entertainment tablets, work laptops, or connected appliances). This is a problem for end-users, who want to differentiate between applications and devices; for content providers (CPs), who want to exercise control over streams of high monetary value; and for Internet service providers (ISPs), who have to accommodate growing traffic volumes without additional revenues. This book develops a series of solution techniques that use SDN to find an optimal balance between the competing requirements of end-users, ISPs, and CPs. In addition to the design and discussions of various architectures, it provides technical details on real-world system implementations and prototypes. As such, it offers a valuable resource for researchers, network architects, network strategists, developers, and all other readers seeking to learn more about the practical value of SDN in future ISP networks.

Most books on linear systems for undergraduates cover discrete and continuous systems material together in a single volume. Such books also include topics in discrete and continuous filter design, and discrete and continuous state-space representations. However, with this magnitude of coverage, the student typically gets a little of both discrete and continuous linear systems but not enough of either. Minimal coverage of discrete linear systems material is acceptable provided that there is ample coverage of continuous linear systems. On the other hand, minimal coverage of continuous linear systems does no justice to either of the two areas. Under the best of circumstances, a student needs a solid background in both these subjects. Continuous linear systems and discrete linear systems are broad topics and each merit a single book devoted to the respective subject matter. The objective of this set of two volumes is to present the needed material for each at the undergraduate level, and present the required material using MATLAB (R) (The MathWorks Inc.).

Caching enables the storage of internet-based content, including web objects, videos and software updates. When web objects are downloaded from the internet or across WAN links, edge caching stores them at the edge of the network. Content can also be proactively cached at the edge based on its predicted popularity. When subsequent requests come for cached material, the content is quickly delivered from edge caching, without the need to download the data again over the WAN. The result is the ability to help save bandwidth, particularly at times of peak network load, increase content delivery, and provide users with a faster and better network experience. This also allows appliances to be forward proxies and decrypt content for caching. Content producers on the internet can add edge caching to their delivery models using content delivery networks (CDNs). In this comprehensive edited book, the editors and authors introduce edge caching from an information theoretic perspective and discuss its role in saving bandwidth. Many physical layer models and techniques, including interference alignment and beamforming are considered, as well as recent advances on intelligent and proactive communication systems capable of recommending content to users to improve quality of experience and spectrum efficiency. The book provides systematic and thorough coverage of edge caching for mobile networks for an audience of researchers, engineers and scientists from academia and the industry working in the fields of ICTs, data science, AI and machine learning.

This book describes algorithmic methods and hardware implementations that aim to help realize the promise of Compressed Sensing (CS), namely the ability to reconstruct high-dimensional signals from a properly chosen low-dimensional "portrait". The authors describe a design flow and some low-resource physical realizations of sensing systems based on CS. They highlight the pros and cons of several design choices from a pragmatic point of view, and show how a lightweight and mild but effective form of adaptation to the target signals can be the key to consistent resource saving. The basic principle of the devised design flow can be applied to almost any CS-based sensing system, including analog-to-information converters, and has been proven to fit an extremely diverse set of applications. Many practical aspects required to put a CS-based sensing system to work are also addressed, including saturation, quantization, and leakage phenomena.
