Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] The existing auction-based wireless spectrum allocation mechanism does not take into account the prevention of Sybil attacks and other related properties; it cannot provide bidders with flexibility in the time dimension. The present invention integrates the auction model in economics, and designs an online dynamic spectrum auction mechanism that can meet secondary users' flexible demands on channels and bid against Sybil attacks; through this mechanism, secondary users can submit their different Demand and the corresponding estimation function are used to bid for the spectrum, which prevents the Sybil attack of illeg...

Abstract

The invention belongs to the technical field of dynamic resource partitioning, and discloses a dynamic spectrum allocation method for multi-channel protection against Sybil attack, and a computer program. In order to defend against Sybil attacks, a spectrum auction model is designed to dynamically manipulate the spectrum auction strategy according to the flexible and real valuation. The bidding relationship among the secondary users is discussed in the model, and the spectrum auction is carried out by designing a specific bidding strategy. Adopting auction theory and mechanism to prevent Sybilattack, spectrum auction is carried out online through bidding strategy. The frequency spectrum allocation method of the invention not only realizes individual rationality and authenticity, but alsocan resist Sybil attack, and dynamically allocates channels on line, thereby improving frequency spectrum efficiency and reusability. According to the evaluation result, the present invention can prevent bidders from manipulating the auction and achieve good spectrum reallocation performance. The method provided by the invention is easy to realize and easy to expand, and is closer to practical application than the spectrum auction method provided by the invention.

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...
