Abstract

IEEE 802.22 is a standard for Wireless Regional Area Network (WRAN) based on cognitive radio techniques. It allows sharing of geographically unused spectrum allocated to the Television Broadcast Service, without causing harmful interference to the licensed users. An open issue in cognitive 802.22 networks is represented by the resource distribution among WRANs. The contribution of this paper is a resource sharing algorithm which assigns resources to overlapped WRANs in such a way to avoid harmful interference among them. Specifically, we propose a collision free resource sharing method which, working in a multichannel environment, aims to assign band to the coexisting WRANs, satisfying their spectrum demand and determining a fair spectrum scheduling. The novel method adapts to the continuous changes of the spectrum availability due to necessity of vacating a channel in case of the incumbent primary users or otherwise due to the addition of unused band. Moreover, the introduced allocation scheme takes into account the issue of spatial diversity, i.e. the case where some channels do not spatially cover all the WRANs. The effectiveness of the proposed multichannel resource sharing scheme is proved through simulations, and the results, compared with other methods already known in literature, show that the algorithm makes a resource assignment which satisfies the requests and improve the use of the available channels, increasing the spectral efficiency.
IEEE 802.22认知网络中的集中式网络间资源共享(CIRS)方案
IEEE 802.22是基于认知无线电技术的无线区域网络(WRAN)标准。它允许共享分配给电视广播服务的地理上未使用的频谱,而不会对持牌用户造成有害干扰。认知802.22网络中的一个开放性问题是wran之间的资源分配问题。本文的贡献在于提出了一种资源共享算法,将资源分配给重叠的WRANs,从而避免WRANs之间的有害干扰。具体来说,我们提出了一种在多信道环境下无冲突的资源共享方法,旨在为共存的WRANs分配频带,满足它们的频谱需求并确定公平的频谱调度。该方法适应了现有主要用户需要腾出信道或增加未使用频段而导致频谱可用性不断变化的情况。此外,引入的分配方案考虑了空间多样性的问题,即某些信道在空间上不能覆盖所有wran的情况。通过仿真验证了所提出的多信道资源共享方案的有效性,并与文献中已知的其他方法进行了比较,结果表明,该算法进行了满足请求的资源分配,提高了可用信道的利用率,提高了频谱效率。
