论文摘要
如今，物联网（IoT）生成了大量数据，并且已将云计算作为用于IoT数据管理的有效解决方案。云资源管理员通常采用复制策略来保证物联网数据的可靠性。这种机制可以大大减少数据访问时间，显然，更多的数据复制品增加了数据存储成本。此外，在Mini Clouds中选择Mini Clouds进行副本分配和对复制品进行排序的过程被认为是NP硬性问题。因此，本文提出了一种基于和谐搜索（HS）算法的方法，以将副本分配给云计算环境中的IoT数据，以减轻数据访问成本。 HS算法在拟议的方法中使用，以确定云计算环境中数据复制的最佳位置。根据实施结果，所提出的方法的表现优于其他方法，并设法显着减少了数据访问时间和延迟以及能耗。
The Internet of things (IoT) generates a plethora of data nowadays, and cloud computing has been introduced as an efficient solution to IoT data management. A cloud resource administrator usually adopts the replication strategy to guarantee the reliability of IoT data. This mechanism can significantly reduce data access time, and evidently, more replicas of data increase the data storage cost. Furthermore, the process of selecting mini clouds for replica allocation and sorting replicas in mini clouds is considered an NP-hard problem. Therefore, this paper proposes an approach based on the harmony search (HS) algorithm to allocate replicas to the IoT data in the cloud computing environment in order to mitigate the data access cost. The HS algorithm was employed in the proposed approach to determine the best location for data replication in the cloud computing environment. According to the implementation results, the proposed approach outperformed the other methods and managed to significantly decrease data access time and delay as well as energy consumption.
