“…BAC-3: In no block and block backoff states, the expression of the one-step transition probabilities using BAC-3 are the same as BAC-1 in (2) and (3). On the other hand, in block transmitting states, the one-step transition probabilities of BAC-3 are different with BAC-1 in (7). Since without block queueing in BAC-3, a FN must return to no block state after the FN transmits or discards its block.…”

Wireless blockchain network is proposed to enable a decentralized and safe wireless networks for various blockchain applications. To achieve blockchain consensus in wireless network, one of the important steps is to broadcast new block using wireless channel. Under wireless network protocols, the block transmitting will be affected significantly. In this work, we focus on the consensus process in blockchain-based wireless local area network (B-WLAN) by investigating the impact of the media access control (MAC) protocol, CSMA/CA. With the randomness of the backoff counter in CSMA/CA, it is possible for latter blocks to catch up or outpace the earlier one, which complicates blockchain forking problem. In view of this, we propose mining strategies to pause mining for reducing the forking probability, and a discard strategy to remove the forking blocks that already exist in CSMA/CA backoff procedure. Based on the proposed strategies, we design Block Access Control (BAC) approaches to effectively schedule block mining and transmitting for improving the performance of B-WLAN. Then, Markov chain models are presented to conduct performance analysis in B-WLAN. The results show that BAC approaches can help the network to achieve a high transaction throughput while improving block utilization and saving computational power. Meanwhile, the trade-off between transaction throughput and block utilization is demonstrated, which can act as a guidance for practical deployment of blockchain.

“…at is to say, rival bidders could still observe the true bid of a bidder. To eliminate the hypothetical trusted auctioneer (in some studies, if the auctioneer is semitrusted, then a semitrusted auction agent would be introduced in the premises that they would not collude with each other), some Software Guard Extension (SGX) approaches were proposed [9]. Recently, Chen et al proposed SAFE, a general secure e-auction framework with privacy preservation [11].…”

“…Spectrum e-auction, which is considered to be one of the most effective ways of solving the spectrum allocation problem, has been widely researched in the past few years [4][5][6][7]. Recently, on account of the rise of the smart contract, some blockchain-based frameworks have also been constructed [8][9][10][11]. ere are three main entities participant in the spectrum e-auction process, namely, seller(s), auctioneers, and buyer(s).…”

5G heterogeneous network (HetNet) is a novel network topology that integrates various kinds of wireless access technologies such as 4G Long-Term Evolution (LTE), Wi-Fi, and so on. Despite greatly improving spectrum efficiency, it poses enormous challenges to spectrum e-auction. Firstly, due to high mobility, bidders may be interested in different spectrums in terms of time or geolocation. Secondly, one’s bidding value should be protected against rival bidders or adversaries to avoid vicious competition as well as privacy leakage. Thirdly, the ubiquitous HetNet requires a trustworthy distributed auction framework rather than a centralized auctioneer-based pattern. Aiming at overcoming these obstacles above, we proposed a blockchain-based combinatorial spectrum e-auction framework. Different from other blockchain-based solutions of using SGX to realize trust processing in the auction phase, we adopt Zether, a privacy-preserving smart contract, as the main building block. Besides, the bidding value is preserved from the beginning to the end, even though the time-consuming Paillier homomorphic encryption and garbled circuits are absent. We provide the auction security by leveraging Σ -Bullets, a zero-knowledge proof mechanism. Theoretical analysis and extensive evaluation also indicate that our approach is better than the state-of-the-art works in terms of efficiency and effectiveness.

“…According to Wang, J and other 4 scholars, they claimed that the potential menace exists due to the semi-honest agent that complete the auction process. Privacy reveals of bidders and the possibility of collusion to manipulate the whole auction led to the scholars' design of a secure spectrum auction protocol, and they finally did theoretical analysis and simulation experiments of it [1]. Similarly, a model designed by Dong, X, and the other 5 scholars, also made the auction system more reliable.…”

Based on the operating mechanism of the spectrum auction, this paper analyzes the bidder's quotation mechanism in the spectrum auction process from both qualitative and quantitative perspectives from the perspective of the 5G basic spectrum. At the same time, they are taking the Canadian spectrum auction as an example, combining actual data to explore the spectrum auction's development process and action mechanism. Studies have shown that spectrum auctions will become an effective tool for people to use higher frequencies as buying and selling spectrum and estimation capabilities in the future, which will help voters achieve the highest benefits.
