US Patent 10257136 Data aggregation in the internet of things

Data aggregation in an internet of things (IoT) system refers generally to collecting data such that the data can be processed in a useful manner. Existing approaches to data aggregation in IoT systems, such as a system including a network of sensors for example, often focus on network logical topology and data transmission scheduling and routing schemes. An IoT system can aggregate data at an application-protocol layer. For example, an IoT node in an IoT system can send a data aggregation request message that is capable of retrieving data from a plurality of different applications. In response, the IoT node may receive data that is representative of a set of nodes that are located downstream in the IoT system from the IoT node.
