“…The findings reveal that the adopted scheme effectively increases spectrum utilization with security and reliability. Further, in [ 49 ], the authors presented a blockchain-based user-autonomy spectrum-sharing framework that efficiently manages the heterogeneous devices of the IoT network. They designed a swarm intelligence approach and a dynamic tip selection algorithm to enhance the system and global utility.…”

Mobile applications have rapidly grown over the past few decades to offer futuristic applications, such as autonomous vehicles, smart farming, and smart city. Such applications require ubiquitous, real-time, and secure communications to deliver services quickly. Toward this aim, sixth-generation (6G) wireless technology offers superior performance with high reliability, enhanced transmission rate, and low latency. However, managing the resources of the aforementioned applications is highly complex in the precarious network. An adversary can perform various network-related attacks (i.e., data injection or modification) to jeopardize the regular operation of the smart applications. Therefore, incorporating blockchain technology in the smart application can be a prominent solution to tackle security, reliability, and data-sharing privacy concerns. Motivated by the same, we presented a case study on public safety applications that utilizes the essential characteristics of artificial intelligence (AI), blockchain, and a 6G network to handle data integrity attacks on the crime data. The case study is assessed using various performance parameters by considering blockchain scalability, packet drop ratio, and training accuracy. Lastly, we explored different research challenges of adopting blockchain in the 6G wireless network.

“…7, we can observe that the convergence time of the proposed algorithm is shorter than Greedy-SM and Random-SM. This is because the proposed algorithm always maximizes the utilities of BOPs and SOPs with simple judgements and calculations according to (13) and ( 14), while Greedy-SM and Random-SM obtain the local optimal utilities of operators with complex calculations.…”

“…With our trust management scheme, malicious UAVs that violate the spectrum sharing rule or provide misleading spectrum sensing results will be punished. Different from the existing works [9–16], our scheme can incentive selfish UAV nodes honestly obey the spectrum sharing data on blockchain and thus their off‐chain malicious behaviours are suppressed. Our contributions are summarized as follows.…”

“…Blockchain is also applied to secure the spectrum-sharing related data (e.g. spectrum allocation results) in wireless networks [9][10][11][12][13][14][15][16]. Notably, these existing works of blockchain based spectrum-sharing assume that participants honestly obey the spectrum sharing data on blockchain without considering off-chain malicious behaviours.…”

Building trust via blockchain in UAV‐assisted ultra‐dense 6G cellular networks

The ultra-dense deployment of unmanned aerial vehicles (UAVs) as mobile small cell base stations (SBS) is expected to support ultra-high-speed, ultra-reliable, and ultra-low-latency wireless connections in sixth generation (6G) wireless cellular networks. Inevitably, the explosively increasing number of SBSs each with ever-shrinking cell size will result in the spectrum scarcity and pose critical challenges to the spectrum management. Towards the centralized spectrum management system, a third-party authority is employed to coordinate the spectrum sensing, sharing, and allocation among participants. However, a centralized authority is vulnerable to numerous security threats, such as single point of failure, denial of service attacks, and privacy disclosure, and cannot guarantee fair and efficient spectrum management without mutual trusts among participants. To address these problems, a novel framework of blockchain-aided spectrum management is designed to securely record the spectrum auction data and spectrum allocation data in the decentralized spectrum sharing. Moreover, a trust management scheme is proposed to evaluate the trusts of all UAVs participating in the decentralized spectrum sharing, where the trust increase depends on legal use of spectrum allocation and honest report of spectrum sensing. In particular, it is shown that the proposed trust management can not only incentivize the UAVs to comply with the legal rule of spectrum sharing in blockchain, but also punish the malicious behaviour that either violates the spectrum sharing rule or provides misleading spectrum sensing results.
