Title: (EN) Techniques for distributing data among nodes based on dynamic spatial/organizational state of a mobile node
(ZH) 基于移动节点的动态空间/组织状态在节点之间分发数据的技术
Abstract: front page image
(EN) Techniques for managing data in a distributed system include receiving first mobile data that includes non-routing data for a mobile node of multiple nodes in a distributed data system. The mobile node is associated with a first data item of multiple data items in the distributed data system. Non-routing data includes organizational data for data items in the distributed database or spatial data, or both. Spatial data includes at least one of a physical location, shape, size, and orientation. A non-topological relationship is determined between the first data item and a different second data item based on the non-routing data. Content is communicated with the mobile node based at least in part on the non-topological relationship. These techniques allow conservation of valuable network resources by communicating only data relevant to a recipient based on the spatial or organizational context of the communicating nodes.

用于管理分布式系统中的数据的技术包括接收第一移动数据,该第一移动数据包括针对分布式数据系统中的多个节点中的一个移动节点的非路由数据。该移动节点被与分布式数据系统中的多个数据项中的第一数据项相关联。非路由数据包括分布式数据库中的数据项的组织数据或空间数据,或者这二者。空间数据包括物理位置、形状、尺寸和朝向中的至少一种。基于非路由数据,第一数据项和不同的第二数据项之间的非拓扑关系被确定。至少部分基于非拓扑关系与移动节点之间传输内容。这些技术允许基于通信节点的空间或组织上下文仅传输与接收相关的数据,从而节省宝贵的网络资源。
