Opportunistic Spectrum Sharing and White Space Access: The Practical Reality

Details the paradigms of opportunistic spectrum sharing and white space access as effective means to satisfy increasing demand for high-speed wireless communication and for novel wireless communication applications This book addresses opportunistic spectrum sharing and white space access, being particularly mindful of practical considerations and solutions. In Part I, spectrum sharing implementation issues are considered in terms of hardware platforms and software architectures for realization of flexible and spectrally agile transceivers. Part II addresses practical mechanisms supporting spectrum sharing, including spectrum sensing for opportunistic spectrum access, machine learning and decision making capabilities, aggregation of spectrum opportunities, and spectrally-agile radio waveforms.

High-level scenarios for the future of cognitive radio business

This paper aims to provide a systematic analysis and formal presentation of high-level scenarios for the future development of Cognitive Radio business ecosystem. It uses the Intuitive Logics as a methodology for constructing four equally probable scenarios in a matrix at the intersection of two identified major uncertainties. The paper shows the importance of using high-level scenarios as a guiding framework for understanding the causal-consequential relationships and actions of different stakeholders that may help in building the strategies for responding and further facilitating the development of Cognitive Radio.

The role of policy in the development of Cognitive Radio systems: Co-evolutionary perspective

In this work we adopt the theoretical framework of co-evolutionary analysis to explore the different roles of relevant stakeholders in the development of Cognitive Radio (CR) systems in the modern wireless market. Our analysis is aimed at yielding better understanding of factors upon which success or failure of commercialization of CR will depend and their possible link to policy and standardisation. Our analysis shows the benefits of co-evolutionary development coordinated across various domains: technology, policy and market. In particular, we build a compelling case that the policy domain and its respective stakeholders represent some of the most crucial factors that could “make or break” the future prospects of technology deployment and its advancement towards commercial success.

State-of-the-Art in Policy and Regulation of Radio Spectrum

This chapter sets the stage for the rest of book by presenting the current state of affairs in the management of radio spectrum and related standardisation and regulatory initiatives pertaining to the emerging fields of CR and DSA. Section 1.1 discusses the international structure of spectrum management from the global ITU level down to the regional and national level. It also outlines how the ITU has started approaching the consideration of DSA challenges. The next Sect. 1.2 looks at how these efforts have been matched by the European regulators. Next, two Sects. 1.3 and 1.4 examine the complex issue of standardisation of CR/DSA technologies, starting from the general overview of work in global and regional standardisation bodies, followed by the analysis of drivers and obstacles. Standardisation is particularly covered because it has intrinsic interactions with regulation. For example, a well-targeted standardisation initiative involving strong industry players and perhaps an industry association can provide significant motivation for regulators to adapt regulations to support that initiative, in support of economic/industrial and national interests. The chapter is concluded by Sect. 1.5 that takes a closer look at the developments in two countries that have been particular champions of CR technologies: namely the United States and the United Kingdom. This is done with a viewpoint on the status of TV White Space access implementation—currently a key driver of DSA.

Cognitive Radio Policy and Regulation

This book offers a timely reflection on how the proliferation of advanced wireless communications technologies, particularly cognitive radio (CR) can be enabled by thoroughly-considered policy and appropriate regulation. It looks at the prospects of CR from the divergent standpoints of technological development and economic market reality. The book provides a broad survey of various techno-economic and policy aspects of CR development and provides the reader with an understanding of the complexities involved as well as a toolbox of possible solutions to enable the evolutionary leap towards successful implementation of disruptive CR technology or indeed any other novel wireless technologies. Cognitive Radio Policy and Regulation showcases the original ideas and concepts introduced into the field of CR and dynamic spectrum access policy over nearly four years of work within COST Action IC0905 TERRA, a think-tank with participants from more than 20 countries. The books subject matter includes:deployment scenarios for CR;technical approaches for improved spectrum sharing;economic aspects of CR policy and regulation;impact assessment of cognitive and software-defined radio; andnovel approaches to spectrum policy and regulation for the age of CR. The book will interest researchers in the field of wireless communications, especially those working with standardization and policy issues, as well as industry and regulatory professionals concerned with radio spectrum management and the general development of wireless communications. Considerable complementary reference material such as power point slides and technical reports that illustrates and expands on the contents of the book is provided on the companion website to the book, found at http://www.cost-terra.org/CR-policy-book

Taxonomy of Cognitive Radio applications

Today there exists no single fully-inclusive classification system for the range of possible different use-cases and applications of Cognitive Radio (CR). This paper aims to fill this gap by proposing a universal taxonomy of CR applications. Based on a thorough review of existing literature we offer a conceptual proposal of universal CR taxonomy made of two classification planes that use respectively the application utility and technological factors to describe the hierarchical branching. The two complementary schemes are suggested to accommodate all the many CR applications proposed today, and can be easily expanded in the future to incorporate any newly proposed applications. The paper concludes by outlining some tangible practical benefits of having a universal taxonomy classification, including unambiguous codification of all CR applications and facilitation of autonomous opportunistic CR link and network formation.

Activity dependent power allocation algorithm for IEEE 802.11 networks

IEEE 802.11 has become one of the most used wireless access technologies amongst home users and Wireless Internet Service Providers (WISPs). Thanks to flexible use and easy deployment the amount of equipment grew exponentially. However, the growing number of wireless devices both at user premises and in WISPs infrastructure leads to increased interference, which reduces the total effective capacity of overused wireless medium. Several new features were adapted in recently released IEEE 802.11ac to address that trend. Nevertheless, 802.11ac still possess the same medium access control mechanisms as used in the first 802.11-generation protocol. This paper proposes an activity dependent power allocation algorithm for IEEE 802.11 networks, which would allow increasing throughput of IEEE 802.11 networks and their radio spectrum use efficiency. The proposed concept utilizes a modified Point Coordination Function mechanism with added power control functionality based on game-theoretic foundations. With the proposed algorithm the Point Coordinator will be able to provide better control of different channel utilization levels and manage power levels of terminal stations in real-time.
