    摘要:

    随着IOT(Internet of Things)服务的规模不断扩大,IOT服务的分布式管理是必然趋势。基于时空相关属性快速发现一组满足要求的IOT服务是IOT服务管理与使用中要解决的首要问题。传统的根据语法或语义进行服务发现的方法通常面对的是海量、离散的服务集合,服务发现时间与服务规模关系密切,并且在多次迭代递进的服务发现请求中结果无法重用。针对上述问题,提出了一种分布式时空相关服务网络的构建方法,利用服务之间的时空聚合关系与时空连接关系在离散、独立的服务之间建立关联,从而通过构建时空相关服务网络对服务进行组织与管理,重点探讨分布式环境下时空相关服务网络的构建、演化方法,以高速公路紧急事件处置场景作为案例,讨论基于服务网络的服务快速发现。

    Abstract:

    With the rapid increase in the number of IOT (Internet of Things) services, distributed management of IOT services is an inevitable trend. Quick discovery of a set of IOT services based on spatial-temporal properties is the primary issue in the management and use of IOT services. The traditional method of service discovery based on syntactic or semantics usually faces a mass and isolated set of services, and the service discovery time is closely related to the service number. Besides, the result cannot be reused in the service discovery request with multiple iterations. To solve the above problems, this paper proposed a method for distributed spatial-temporal properties related service network building, using the paradigmatic relations of spatial-temporal properties to build service connection relationship between the isolated services. The services were organized and managed by constructing spatial-temporal related service network. The focus of this research was on the construction and evolution of spatial-temporal related service network in distributed environment. Finally, the rapid discovery of services based on service network was discussed in the case of highway emergency handling scenario.
