物联网应用化智能网关技术

Applied Smart Gateway of IOT

针对物联网应用需求的多样化、标准的不统一,提出了一种应用化的智能网关,增强了物联网网关的通用性与智能信息处理能力和应用服务能力。该网关基于OSGi中间件技术及其可动态加载特定物联网应用的框架,主要实现基于XML的多种传感器适配、智能信息处理模块或应用服务动态加载、上行流量传输优化与调度等相关功能。应用化的智能网关既能以传统网关的形式部署在大规模物联网应用中执行信息传输功能,也能独立部署在小规模物联网中执行智能信息处理和直接提供应用服务的功能。

For the variety of applications and lacking of standards for IOT, this paper proposes an applied smart gateway to improve the commonality, ability of information processing and application service of the gateway of IOT. Based on the OSGi middleware technologyand dynamic loading of applications framework, the smart gateway includes XML-based adaptation of sensors, dynamic loading of services, transmission optimization and scheduling of the upstream trafifc and other related functions. Applied smart gateway could be deployed not only in the large-scale scenario to transport information of IOT, but also in the smal-scale scenario to process the information and provide application service.
