Описание: The wireless medium is a shared resource. If nearby devices transmit at the same time, their signals interfere, resulting in a collision. In traditional networks, collisions cause the loss of the transmitted information. For this reason, wireless networks have been designed with the assumption that interference is intrinsically harmful and must be avoided. This book, a revised version of the author's award-winning Ph.D. dissertation, takes an alternate approach: Instead of viewing interference as an inherently counterproductive phenomenon that should to be avoided, we design practical systems that transform interference into a harmless, and even a beneficial phenomenon. To achieve this goal, we consider how wireless signals interact when they interfere, and use this understanding in our system designs. Specifically, when interference occurs, the signals get mixed on the wireless medium. By understanding the parameters of this mixing, we can invert the mixing and decode the interfered packets; thus, making interference harmless. Furthermore, we can control this mixing process to create strategic interference that allow decodability at a particular receiver of interest, but prevent decodability at unintended receivers and adversaries. Hence, we can transform interference into a beneficial phenomenon that provides security. Building on this approach, we make four main contributions: We present the first WiFi receiver that can successfully reconstruct the transmitted information in the presence of packet collisions. Next, we introduce a WiFi receiver design that can decode in the presence of high-power cross-technology interference from devices like baby monitors, cordless phones, microwave ovens, or even unknown technologies. We then show how we can harness interference to improve security. In particular, we develop the first system that secures an insecure medical implant without any modification to the implant itself. Finally, we present a solution that establishes secure connections between any two WiFi devices, without having users enter passwords or use pre-shared secret keys.

Описание: Mobile and wireless communications applications have a clear impact on improving the humanity wellbeing. Societal development will lead to changes in the way mobile and wireless communication systems are used. Essential services such as e-banking, e-learning and e-health will continue to proliferate and become more mobile. On demand information and entertainment will be delivered over mobile and wireless communication systems. The wirelessly connected Internet of things will make our everyday life more efficient, comfortable and safer. It is apparent, even to the most casual observer, that a veritable revolution in telecommunications has taken place within recent years. The use of wireless communications has expanded dramatically worldwide. Cell phones are ubiquitous. Although most such mobile terminals still carry voice principally, more and more users are sending and receiving data and image applications. Wi-Fi, an example of a wireless local area network (LAN), has caught on spectacularly, joining the major cellular networks deployed throughout the world. Smart and advanced wireless communication environments represent the future technology and evolutionary development step in homes, hospitals, industrial, vehicular and transportation systems. The purpose of Mobile and Wireless Communications Network Layer and Circuit Level Design is to highlight several aspects of mobile and wireless communications networks. It covers the recent development in ad hoc and sensor networks, the implementation of state of the art of wireless transceivers building blocks and recent development on optical wireless communication systems. A student or reader of the book, provides more advanced material, should come away with a thorough grounding in the fundamental aspects of mobile wireless communication, as well as an understanding of the principles of operation of second- and third-generation cellular systems and wireless LAN.
