基于EXI的物联网信息交换数据格式设计与实现

摘要

通常在物联网系统中使用XML作为数据交换格式,但由于物联网中大量存在对功耗要求较高的移动感知设备,所以本文基于EXI(Efficient XML Interchange Format)设计适合于物联网数据交换格式,并使用真实物联网数据验证其可行性和效率.实践发现使用 EXI 格式的物联网数据在效率上比之前 XML 格式的数据在传输效率有了很大的提高,更加适合物联网系统使用,如果在各大物联网系统统一推广使用,是现在解决不同行业物联网系统信息孤岛问题的一个方案.%The technology usually used in the IOT system as a data exchange format is XML,but because there are a lot of mobile sensing devices which have strict power requirements in the IOT systems.So based on EXI(Efficient XML Interchange Format)design suitable for networking data exchange format,and networking with real data verify the feasibility and efficiency.Practice found that the use EXI format data to improve things on the efficiency than the data in the XML format before transmission efficiency 37.8%,more suitable system of things,if the promotion of the use of a unified system in the major things,is now resolve things in different industries a program system information island issue.
