基于客户端马尔可夫模型的分布式雾数据存储中移动用户的位置预测

Predictive Replica Placement for Mobile Users in Distributed Fog Data Stores with Client-Side Markov Models

Malte Bellmann, Tobias Pfandzelter, David Bermbach

摘要:

在雾环境中,消费和产生数据的移动客户端非常丰富,只有将数据存储在物理上非常接近的位置,才能实现对这些数据的低延迟访问。为了以有效的方式调整雾数据存储中的数据复制,并使客户端数据在最接近客户端的雾节点上可用,系统需要预测客户端移动和数据消耗暂停。在本文中,我们提出了马尔可夫模型算法的变化,可以在客户端上运行,以增加数据的可用性,同时最大限度地减少多余的数据。在一个模拟中,我们发现在最近的节点上的数据的可用性可以提高35%,而不会产生全局复制的存储和通信开销。

英文摘要:

Mobile clients that consume and produce data are abundant in fog environments and low latency access to this data can only be achieved by storing it in their close physical proximity. To adapt data replication in fog data stores in an efficient manner and make client data available at the fog node that is closest to the client, the systems need to predict both client movement and pauses in data consumption. In this paper, we present variations of Markov model algorithms that can run on clients to increase the data availability while minimizing excess data. In a simulation, we find the availability of data at the closest node can be improved by 35% without incurring the storage and communication overheads of global replication.
