区间微调分支界定混合P2P云存储喷泉编码优化
Hybrid P2P storage and cloud storage fountain coding optimization based on branch definition of interval point micro adjustment
摘要
Abstract
In the traditional cloud storage system,the data upload time is long and the bandwidth control is also not ideal.Therefore,this paper proposed a P2P storage and cloud fountain coding optimization algorithm based on dynamic step size to solve the above problems.First,it designed a hybrid peer-to-peer network cloud storage system,which constructed by the fountain code,the parameter control unit,the node manager and the upload scheduling program.Secondly,according to the problem of non-ideal in parameter control,and poor effect of data transmission,based on the branch defined algorithm,it designed the dynamic step branch bound algorithm,which could reduce the computational complexity,and could effective deal with the problem of long time uploading and network bandwidth decreased.Finally,the algorithm is better than the contrast algorithm in the data uploading time and data redundancy by simulation,which verifies the effective of the proposed algorithm.关键词
