摘要: 随着无线网络的快速发展,物联网中频谱资源的高效分配问题亟需解决,为此,提出一种基于信任的频谱资源分配机制TSRA。借鉴拍卖理论建立频谱资源拍卖系统模型,根据信任理论确定用户间的信任关系以缩小客户网络范围,利用属性加密理论保护交易数据。在此基础上,采用改进的蚁群算法为用户合理规划资源分配路径,从而实现频谱资源的多目标分配。实验结果表明,该机制可以为用户的交易数据提供细粒度的保护,且具有较高的社会效益和较低的系统计算与通信开销。

Abstract: With the rapid development of wireless networks,the problem of efficient allocation of spectrum resources in the Internet of Things(IoT) needs to be solved.Therefore,this paper proposes TSRA,a trust based spectrum resources allocation mechanism.By referring to the auction theory,the suction system model of spectrum resources is established.According to the trust theory,the trust relationship between users is determined to narrow down the scope of customer network and the transaction data is protected by the attribute encryption theory.On this basis,the improved ant colony algorithm is used to make reasonable plan for the resources allocation path,so as to achieve multi-objective allocation of spectrum resources.Experimental results show that the proposed mechanism can provide fine-grained protection for users' transaction data.It has high social benefits and low system computing and communication costs.

Key words: spectrum resource, trust, encryption, auction theory, ant colony algorithm
