论文摘要
在物联网中，数据的相关性通常取决于数据生产者和消费者的地理环境。但是，当今的数据分发服务主要集中在数据内容上，而不是地理上下文上，这可能有助于减少许多物联网方案中多余数据的传播。在本文中，我们建议使用与设备关联的地理文化信息来控制数据分布。我们定义了地理位置维度的存在，并将我们的定义与相关工作的概念进行比较。 此外，我们设计了GeoBroker，这是一种使用事物的位置以及信息和订阅的地理位置的数据分配服务来控制数据分发。这样，我们启用了新的IoT应用程序方案，同时还提高了通过仅传递相关消息至关重要的方案的总体系统效率。我们根据概念验证原型和几个实验评估我们的方法。
In the Internet of Things, the relevance of data often depends on the geographic context of data producers and consumers. Today's data distribution services, however, mostly focus on data content and not on geo-context, which could help to reduce the dissemination of excess data in many IoT scenarios. In this paper, we propose to use the geo-context information associated with devices to control data distribution. We define what geo-context dimensions exist and compare our definition with concepts from related work. Furthermore, we designed GeoBroker, a data distribution service that uses the location of things, as well as geofences for messages and subscriptions, to control data distribution. This way, we enable new IoT application scenarios while also increasing overall system efficiency for scenarios where geo-contexts matter by delivering only relevant messages. We evaluate our approach based on a proof-of-concept prototype and several experiments.
