物联网环境下负载均衡的低代价云存储数据副本分布
Load-balancing and low cost cloud data replica distribution method in Internet of Things environment
摘要
Abstract
In order to meet the requirements of mobile terminal in terms of mobility and real time in the Internet of Things, according to the model of replica distribution and data access in cloud storage, a method for selecting low access cost storage server was presented on the basis of access positions and frequencies. Considering the effect of the load on access cost, the load-balancing technique by updating cost matrix dynamically was presented. The results show that when achieving the minimum number of replicas, the replicas are adaptively distributed to the storage servers according to the data access status with low access cost. With reduced accessing cost, avoided replicas non-equalizing distribution and enhanced load balance, the method is favorable in management of cloud storage in the Internet of Things.关键词
