This brief investigates spectrum efficient and energy efficient strategies, known as cognitive radio networks (CRNs), to ensure secure cooperation between licensed and unlicensed users. The authors address issues of spectrum scarcity, spectrum sensing, transmission performance, trust-aware cooperation, and secure communications. Two security-aware cooperation based spectrum access schemes are presented. The first is a trust-aware cooperative framework for CRNs to improve the throughput or energy efficiency of licensed users and offer transmission opportunities to unlicensed users, taking into consideration the trustworthiness of unlicensed users. The second scheme is a cooperative framework to enhance secure communications of licensed users. An introduction to CRNs and literature survey enhance the discussion while numerical results are provided to demonstrate the viability of the proposed schemes. The brief is designed for researchers and professionals working with cognitive radio networks or interested in cooperation based access. Advanced-level students studying computer communication networks and communications engineering will also find this brief useful.

The objective of this SpringerBrief is to present security architectures and incentive mechanisms to realize system availability for D2D communications. D2D communications enable devices to communicate directly, improving resource utilization, enhancing user’s throughput, extending battery lifetime, etc. However, due to the open nature of D2D communications, there are two substantial technical challenges when applied to large-scale applications, that is, security and availability which is demonstrated in this book. This SpringerBrief proposes a secure data sharing protocol, which merges the advantages of public key cryptography and symmetric encryption, to achieve data security in D2D communications. Furthermore, a joint framework involving both the physical and application layer security technologies is proposed for multimedia service over D2D communications thus the scalable security service can be achieved without changing the current communication framework. Additionally, as the system availability largely depends on the cooperation degree of the users, a graph-theory based cooperative content dissemination scheme is proposed to achieve maximal Quality of Experience (QoE) with fairness and efficiency. This SpringerBrief will be a valuable resource for advanced-level students and researchers who want to learn more about cellular networks.

Cognitive networks can dynamically adapt their operational parameters in response to user needs or changing environmental conditions. They can learn from these adaptations and exploit knowledge to make future decisions. Cognitive networks are the future, and they are needed simply because they enable users to focus on things other than configuring and managing networks. Without cognitive networks, the pervasive computing vision calls for every consumer to be a network technician. The applications of cognitive networks enable the vision of pervasive computing, seamless mobility, ad-hoc networks, and dynamic spectrum allocation, among others. In detail, the authors describe the main features of cognitive networks clearly indicating that cognitive network design can be applied to any type of network, being fixed or wireless. They explain why cognitive networks promise better protection against security attacks and network intruders and how such networks will benefit the service operator as well as the consumer. Cognitive Networks Explores the state-of-the-art in cognitive networks, compiling a roadmap to future research. Covers the topic of cognitive radio including semantic aspects. Presents hot topics such as biologically-inspired networking, autonomic networking, and adaptive networking. Introduces the applications of machine learning and distributed reasoning to cognitive networks. Addresses cross-layer design and optimization. Discusses security and intrusion detection in cognitive networks. Cognitive Networks is essential reading for advanced students, researchers, as well as practitioners interested in cognitive & wireless networks, pervasive computing, distributed learning, seamless mobility, and self-governed networks. With forewords by Joseph Mitola III as well as Sudhir Dixit.

Future services and applications dependent on the Internet of Things (IoT) stand to benefit significantly from the use of Wireless Sensor Networks (WSNs). However, WSNs operating in unlicensed frequency bands are increasingly vulnerable to interference due to spectrum congestion. Cognitive Radio Wireless Sensor Networks (CR-WSNs) provide a promising solution by allowing sensor nodes to opportunistically access licensed spectrum bands. Yet, equipping energy-constrained sensor nodes with cognitive capabilities such as channel sensing, opportunistic access, and channel switching poses significant performance and energy-efficiency challenges. The integration of WSNs with the Cognitive Internet of Things (CIoT) demands the development of robust MAC and spectrum access architectures that allow coexistence with legacy wireless systems. Existing spectrum access paradigms often suffer from increased energy consumption and higher collision rates due to interference from competing users. Moreover, limited research has been conducted on multi-channel CR-WSNs, leading to suboptimal spectrum utilization. This paper proposes an Energy-Efficient Spectrum Access (EESA) model tailored for multi-channel mobile CR-WSNs, aimed at improving the overall performance of energy-constrained cognitive radio networks. Experimental results demonstrate that EESA outperforms conventional models in terms of throughput and energy efficiency, making more effective use of available spectrum resources. To address the issue of dynamic spectrum access in mobile settings, this study introduces the Dynamic and Efficient Channel Access (DECA) method. DECA integrates both temporal and spatial information to minimize user interference and improve performance. Experimental evaluations show that DECA significantly reduces packet collisions and enhances successful packet transmissions, throughput, and energy efficiency compared to existing techniques. However, DECA does not inherently provide fairness in channel access. To overcome this limitation, the research introduces the Throughput Maximization Channel Access Fairness (TMCAF) model, which reduces interference by modeling secondary user behavior patterns. TMCAF incorporates both shared and non-shared channel access strategies to enhance network performance. Results indicate that TMCAF improves throughput and reduces network collisions compared to state-of-the-art models. However, TMCAF still lacks optimal performance guarantees. Recent advances in Deep Learning (DL), Reinforcement Learning (RL), and Game Theory (GT) have been employed for intelligent channel access in CR-WSNs. However, these approaches typically face two key limitations: Lack of balance between maximizing secondary user (SU) throughput and minimizing primary user (PU) interference in multi-channel environments. Inability to ensure fair network access for SUs in energy-constrained CR-WSNs. To address these issues, this study proposes a novel Throughput Maximization Channel Access Fairness using Game Theory (TMCAF-GT) approach. The TMCAF-GT method incorporates both shared and non-shared access techniques, leveraging game-theoretic modeling to optimize spectrum usage while ensuring access fairness and energy efficiency.

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.
