Failure Detection Algorithm based on Wavelet Transform and Combinational Models for Cloud Computing

失效检测系统在云计算环境中起着失效检测、容灾等重要作用。文章对现有失效检测算法进行研究和总结,以小波变换与组合模型为基础,建立了基于小波变换与组合模型的失效检测算法WAFD,并进行了相关实验。分析及实验表明,在检测时间相同的条件下,WAFD可以达到更低的错误率。

Failure detection system plays an important role as failure detection and system disaster recovery in a cloud computing environment. In this paper, we analysis the advantages and disadvantages of existing FD algorithms based on the research and summary of those algorithms. As the wavelet transform and combinational models begin to be used in network traffic prediction, we create a FD algorithm based on this model, WAFD. Experimental results demonstrate that our algorithm can reach lower mistake rate in the same condition of detection time.
