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.

Cooperation in Wireless Networks: Principles and Applications covers the underlying principles of cooperative techniques as well as several applications demonstrating the use of such techniques in practical systems. The book is written in a collaborative manner by several authors from Asia, America, and Europe. This book puts into one volume a comprehensive and technically rich appraisal of the wireless communications scene from a cooperation point of view.

Cross-layer design seeks to enhance the capacity of wireless networks significantly through the joint optimization of multiple layers in the network, primarily the physical (PHY) and medium access control (MAC) layers. Although there are advantages of such design in wireline networks as well, this approach is particularly advantageous for wireless networks due to the properties (such as mobility and interference) that strongly affect performance and design of higher layer protocols. This unique monograph is concerned with the issue of cross-layer design in wireless networks, and more particularly with the impact of node-level multiuser detection on such design. It provides an introduction to this vibrant and active research area insufficiently covered in existing literature, presenting some of the principal methods developed and results obtained to date. Accompanied by numerous illustrations, the text is an excellent reference for engineers, researchers and students working in communication networks.

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.
