Design for Spatiotemporal Information Cloud Platform of Smart City Based on OSGi

Abstract

Abstract In 2009, IBM put forward the development policy of building “smart city” before building “smart earth”. In response to this policy, the National Bureau of Surveying and Mapping issued “The Notification on the Development of Smart City Spatiotemporal Information Cloud Platform”, which formally took the construction spatiotemporal information cloud platform of smart city as a pilot project. In this paper, the OSGi (Open Service Gateway Initiative) technology is used as the framework. Developing component on demand is realized by the SOA architecture and OSGi technology, which improves the efficiency of developing software, shortens the cycle of developing software and saves labor costs. Resource access is achieved through RESTful services, and distributed coordination services are implemented through Zookeeper.
