Available in PDF, EPUB and Kindle. Book excerpt: This book introduces readers to the fundamentals of the cross-technology coexistence problem in heterogeneous wireless networks. It also highlights a range of mechanisms designed to combat this problem and improve network performance, including protocol design, theoretical analysis, and experimental evaluation. In turn, the book proposes three mechanisms that can be combined to combat the cross-technology coexistence problem and improve network performance. First, the authors present a fast signal identification method. It provides the basis for the subsequent protocol design and allows heterogeneous devices to adopt proper transmission strategies. Second, the authors present two cross-technology interference management mechanisms in both the time domain and the frequency domain, which can mitigate interference and increase transmission opportunities for heterogeneous devices, thus improving network performance. Third, they present a cross-technology communication mechanism based on symbol-level energy modulation, which allows heterogeneous devices to transmit information directly without a gateway, improving transmission efficiency and paving the way for new applications in IoT scenarios. Lastly, they outline several potential research directions to further improve the efficiency of cross-technology coexistence. This book is intended for researchers, computer scientists, and engineers who are interested in the research areas of wireless networking, wireless communication, mobile computing, and Internet of Things. Advanced-level students studying these topics will benefit from the book as well.

Book excerpt: With the upcoming pervasive deployment of wireless networks and devices on the unlicensed band, co- channel interference caused by frequency collisions among coexisting networks have become one of the major performance limiting challenges. In recent years, the coexistence issue has gained increasing attention. However, many collision avoidance schemes are not applicable to multiple frequency hopped networks, mainly due to the fact that the frequency channels of frequency hopped signals are constantly changing and the hop sequence of one network to another is unknown. In this book, a comprehensive framework for co-channel interference mitigation and robust coexistence of multiple frequency hopped networks is developed, multiple novel techniques are introduced, and the system modeling, design, theoretic analysis, simulation, and testbed implementation are presented. This book is useful to professionals and researchers in the wireless communications field. It is also beneficial for engineers seeking new technologies to improve their wireless products' performance and to lead the market.

Available in PDF, EPUB and Kindle. Book excerpt: Wireless has quickly become an irreplaceable medium for communication, but by their very nature, wireless transmissions are vulnerable to RF interference from various sources. This weakness is a growing problem for technologies that operate in unlicensed frequency bands, as these bands are becoming more crowded over time. The increasing density of radios, coupled with the growing number of different protocols, dictates that future wireless devices will require the ability to coexist and operate in a crowded and often unregulated electromagnetic environment. This dissertation presents a set of architectures and mechanisms for wireless coexistence. These mechanisms are intended as general primitives, enabling future wireless networks to be architected such that they are aware of who their RF neighbors are, what they are doing, and how to respond to them. We design and develop two systems, each demonstrating how changes at different levels across the network stack can provide significant gains. Degrees Of Freedom (DOF) is a robust and accurate technique to detect activity in any band of the relevant spectrum, while Picasso is an extensible radio design which allows the device to more easily exploit the fragmented bands which are available. This dissertation contributes to advancing the state of the art in wireless network design in multiple ways. First, the systems in this dissertation present novel algorithms that span signal processing, circuit design, and software systems. Not only do these algorithms enrich existing theory, they are designed with practical implementations in mind - helping to bridge the gap between theory and practice. Second, we present prototype implementations and testbed evaluations of our systems. Our results demonstrate that our systems deliver significantly improved performance in crowded interferencecentric environments, compared to the state-of-the-art. Finally, the work in this dissertation demonstrates that by having layers work cooperatively, rather than in isolation, common goals of high throughput and reliability in dense interference scenarios are much more practical to achieve. In particular, DOF demonstrates that more fine-grained information passed between the PHY and the MAC enables the MAC to make more informed and intelligent decisions regarding how to respond to the varying sources of interference. In the same vain, Picasso demonstrates that increased RF isolation can significantly lessen the burden on PHY filtering and MAC coordination - similarly allowing the three to share in the task of exploiting fragmented spectrum. We believe that the systems in this dissertation make a compelling and strong argument for cross-layer interdisciplinary wireless network design in order to solve the problems of wireless coexistence.

Available in PDF, EPUB and Kindle. Book excerpt: Spectrum Sharing in Wireless Networks: Fairness, Efficiency, and Security provides a broad overview of wireless network spectrum sharing in seven distinct sections: The first section examines the big picture and basic principles, explaining the concepts of spectrum sharing, hardware/software function requirements for efficient sharing, and future trends of sharing strategies. The second section contains more than 10 chapters that discuss differing approaches to efficient spectrum sharing. The authors introduce a new coexistence and sharing scheme for multi-hop networks, describe the space-time sharing concept, introduce LTE-U, and examine sharing in broadcast and unicast environments. They then talk about different cooperation strategies to achieve mutual benefits for primary users (PU) and secondary users (SU), discuss protocols in a spectrum sharing context, and provide different game theory models between PUs and SUs. The third section explains how to model the interactions of PUs and SUs, using an efficient calculation method to determine spectrum availability. Additionally, this section explains how to use scheduling models to achieve efficient SU traffic delivery. The subject of the fourth section is MIMO-oriented design. It focuses on how directional antennas and MIMO antennas greatly enhance wireless network performance. The authors include a few chapters on capacity/rate calculations as well as beamforming issues under MIMO antennas. Power control is covered in the fifth section which also describes the interference-aware power allocation schemes among cognitive radio users and the power control schemes in cognitive radios. The sixth section provides a comprehensive look at security issues, including different types of spectrum sharing attacks and threats as well as corresponding countermeasure schemes. The seventh and final section covers issues pertaining to military applications and examines how the military task protects its data flows when sharing the spectrum with civilian applications.

Available in PDF, EPUB and Kindle. Book excerpt: In the last decade, there have been several technological trends that have occurred together and have caused a shift in how wireless systems will be deployed. The significant increase in the capabilities of mobile devices, combined with the proliferation of Internet enabled services, and the improvement in the communication support provided by new waveforms for wireless communications, have initiated a shift from the traditional, macrocell-based cellular network to new forms of radio access technologies (RATs) involving multiple, smaller cells deployed in vicinity of each other. These small cells will often support diverse wireless technologies and be operated by different providers. The resulting heterogeneity, unfortunately, can lead to serious internetwork interference that can negate the improvement in overall system performance that was the original motivation for employing many small cells in close proximity. In this thesis, we examine different technologies that are needed for flexible spectrum management to support the coordination that is needed for coexistence between many small cell wireless networks. Motivated by the need for internetwork architectures that support spectrum coordination, we (1) conduct performance evaluation associated with the joint deployment of mobile and fixed hotspot networks, (2) develop spectrum models that characterize interference among different wireless entities, (3) provide new methods for efficient hardware emulation of wireless channels, (4) devise algorithms that estimate radio spectrum usage, and (5) provide algorithms for coordination between different wireless systems to improve the overall system performance and spectrum efficiency. The first part of the thesis investigates spectrum coexistence in wireless networks by exploring the underlying performance challenges that exist when mobile hotspots are deployed in an environment of densely deployed, static wireless access networks. Next part of thesis investigates design of hardware emulator of radio channels to accurately capture the effect of real-world wireless channels upon communications waveforms while minimizing computational complexity. Next, we explore a fundamental building block of spectrum management for supporting better utilization of radio spectrum which involves predicting the impact that an emitter will have at different geographic locations. We then examine various challenges associated with coordinating spectrum access between different wireless technologies by exploring the specific case of Wi-Fi and LTE coexistence in emerging unlicensed frequency bands. Finally, recognizing the broad challenges associated with addressing spectrum coexistence in emerging wireless systems, we identify several directions for future investigation and suggest different approaches for tackling these challenges.

Book excerpt: With the upcoming pervasive deployment of wireless networks and devices on the unlicensed band, co-channel interference caused by frequency collisions among coexisting networks have become one of the major performance limiting challenges. In recent years the coexistence issue has gained increasing attention. However, many collision avoidance schemes are not applicable to multiple frequency hopped (FH) networks, mainly due to that the frequency channels of FH signals are constantly changing and the hop sequence of one network is unknown to another. In this project, we develop a dual channel transmission technique for co-channel interference mitigation and robust coexistence of multiple wireless networks. This report describes the system modeling, design, theoretic analysis, simulation and testbed implementation involved in the aforementioned framework.
