Mobile clients that consume and produce data are abundant in fog environments. Low latency access to this data can only be achieved by storing it in close physical proximity to the clients. Current data store systems fall short as they do not replicate data based on client movement. We propose an approach to predictive replica placement that autonomously and proactively replicates data close to likely client locations.

翻译：消费和生成数据的移动客户在雾环境中非常丰富,只有将这些数据储存在离客户很近的地方,才能实现低延迟访问。 目前的数据存储系统由于不能根据客户流动情况复制数据,因此不完善。 我们提出了一种预测性复制定位方法,即自动和主动地在接近可能客户的地点复制数据。
