中文摘要：
基于上下文感知的云计算平台为用户提供了一种新型、可靠、高效的数据服务模式.面向智慧城市大数据的存储管理服务中,复杂、多源、动态大数据的存储出现了效率低和可靠性差的问题.因此提出构建一种基于上下文感知的云计算平台的思路,采用基于上下文感知的云计算平台的四层结构,上下文感知算法实现智慧城市大数据的存储.理论分析和模式测试结果表明基于上下文感知的云计算平台满足了动态大数据的可靠存储的前提下,降低了数据分布式影响,极大提高了智慧城市大数据的存储管理能力.
英文摘要：
The cloud computing platform based on context-aware provides a new,reliable and efficient data service pattern for users.For the storage and management of Big Data in ITS（Intelligent Transport System）,there are some difficulty missions that be low efficiency and complex reliability of storage,multi-source and dynamic data.In this paper,firstly gives the idea of the cloud computing platform based on context aware,secondly builds the four-layers structure model,then uses the context aware algorithm to achieve ITS Big Data storage.Theoretical analysis and model test results,and be showed that cloud computing platform based on context-aware to meet the premise of reliable dynamic data storage and reduce the influence of distributed data,greatly improving the ITS Big Data storage and analysis capabilities.
