随着传感器网络以及信息和通信技术的快速发展，全球传感器网络（WSW）的愿景正在成为现实。然而，缺乏可以将独立的地理传感器网络聚合成连贯的空间传感器网络（SSW）的空间信息基础设施。 SSW 愿景给当今的 GIService 系统带来了两个架构挑战：(1) 可扩展性和 (2) 互操作性。本文介绍了 GeoSWIFT 2.0，这是一种新的可扩展且可互操作的 SSW 架构。 GeoSWIFT 2.0 具有可扩展性——它通过使用完全去中心化的 P2P 空间查询框架消除了所有单点故障和系统性能瓶颈。 GeoSWIFT 2.0 还具有互操作性——它将可互操作的传感器网络标准与可扩展的 P2P 框架集成在一起。
With the rapid advances in sensor network, and information and communication technologies, the vision of a World-Wide Sensor Web (WSW) is becoming a reality. However, there is a lack of a spatial information infrastructure that could aggregate the independent geo-sensor networks into a coherent Spatial Sensor Web (SSW). The SSW vision brings two architectural challenges to today’s GIService systems: (1) scalability and (2) interoperability. This paper introduces GeoSWIFT 2.0, a new scalable and interoperable SSW architecture. GeoSWIFT 2.0 is scalable – it removes all single points of failure and system performance bottlenecks by using a fully decentralized P2P spatial query framework. GeoSWIFT 2.0 is also interoperable – it integrates interoperable sensor web standards with the scalable P2P framework.
