Dynamic frequency spectrum allocation method and computer program for multi-channel anti-sybil attack

Abstract

The invention belongs to the technical field of dynamic resource division, and discloses a multi-channel anti-Sybil attack dynamic frequency spectrum allocation method and a computer program; it defends against the Sybil attack and dynamically corresponds to a flexible real valuation to quote an anti-strategy manipulation spectrum auction model , discuss the bidding relationship between sub-users in the model, and carry out spectrum auction by designing a specific bidding strategy; adopt auction theory and mechanism to prevent Sybil attacks, and carry out online spectrum auction through bidding strategy. The spectrum allocation method of the present invention can not only realize individual rationality and authenticity, but also resist Sybil attacks, and dynamically allocate channels online, which improves spectrum efficiency and reusability; according to the evaluation results, the present invention can prevent bidders from manipulating the auction, and Achieve good spectrum reallocation performance. The method proposed by the invention is easy to implement and easy to expand, and is closer to practical application than the proposed spectrum auction method.

Description

technical field [0001] The invention belongs to the technical field of dynamic resource division, and in particular relates to a dynamic spectrum allocation method and a computer program for multi-channel anti-Sybil attack. Background technique [0002] Currently, the existing technology commonly used in the industry is this: The radio spectrum is a critical but scarce resource for wireless communication. With the emergence of software-defined radios (SDR, software-definedradios) and wireless devices, the problem of spectrum shortage is becoming more and more serious, and has become a bottleneck for the rapid development of the wireless communication industry. In traditional static spectrum allocation mechanisms, long-term spectrum licenses are issued to wireless devices, resulting in low spectrum utilization due to traffic fluctuations. To improve spectrum utility, dynamic spectrum access mechanisms have been proposed to reallocate spectrum resources, where spectrum owners...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems in the existing technology are: the existing auction-based wireless spectrum allocation mechanism does not take into account the prevention of Sybil attacks and other related properties, and there are many defects; and it cannot provide bidders with flexibility in the time dimension

That is, existing algorithms cannot prevent Sybil attacks and consider the flexibility of the time dimension of the spectrum
