【摘要】：目前提出的物联网应用系统构建方法不少是基于面向服务的体系结构(SOA),原理是将物端资源与云端资源提供的感知、执行与数据处理等能力分别抽象为实体服务和云服务.物联网服务中间件是在实体服务和云服务之上用于支撑物联网任务编程、发现满足任务需求的服务集以及实现各类服务之间互联与互操作的基础结构软件.由于实体服务的异构性、大规模性、动态可用性、情境感知性、时空相关性、资源受限性和执行冲突性,目前构建物联网服务中间件仍面临挑战.该文首先给出了物联网服务中间件的功能模型,并以此为参考,结合实体服务的特性,具体指出了设计与实现物联网服务中间件各功能模块所面临的挑战;接着系统地总结了物联网服务中间件各功能模块的实现方法;然后根据服务描述、服务注册管理、服务发现以及服务组合与任务编程接口的研究进展,对目前已经提出的物联网服务中间件的功能属性进行了分类比较;最后,展望了物联网服务中间件的发展趋势,并指出了未来还需进一步改进和完善的功能.
[Abstract]:At present, many of the methods of constructing Internet of things application systems are based on the service-oriented architecture. The principle is to abstract the perception, execution and data processing capabilities of physical and cloud resources into entity services and cloud services, respectively. Internet of things service middleware is an infrastructure software which is used to support the task programming of the Internet of things on the basis of entity services and cloud services, to find the service set that meets the requirements of the tasks and to realize the interconnection and interoperation among various services. Because of the heterogeneity, large-scale, dynamic availability, situational awareness, spatio-temporal correlation, resource constraint and execution conflict of entity services, the construction of Internet of things service middleware is still facing challenges. In this paper, the function model of the Internet of things service middleware is given, and the challenges of designing and implementing the middleware function modules are pointed out according to the characteristics of the entity service. Then it summarizes the implementation methods of each function module of the Internet of things service middleware, and then according to the service description, service registration management, service discovery, service composition and task programming interface research progress. The functional attributes of Internet of things service middleware are classified and compared. Finally, the development trend of Internet of things service middleware is prospected, and the functions that need to be further improved and improved in the future are pointed out.
