  • Patent number: 10862988
    Abstract: Methods and systems for operating a sensor network are provided. In one example, a server may provide graphical data representing a hierarchical sensor network for displaying at a client device. The server may receive a selection to display sensor data from a first node of the nodes of the hierarchical sensor network and determine, based on the selection, a hierarchical sensor label associated with one or more first sensors of the hierarchical sensor network corresponding to the first node. The server may also receive a plurality of messages including sensor data generated by a plurality of sensors of the hierarchical sensor network from an in-bound real-time message processor, and identify a first set of messages based on the hierarchical sensor label. The server may extract the sensor data from the first set of messages and provide the sensor data for displaying at the client device.

  • Patent number: 10772141
    Abstract: Methods and systems for peer-to-peer communication are provided. In one example, a first device may receive, from a server, a pairing code and a first handshake code. The first device may transmit at least a first portion of the pairing code in a first broadcast message and receive, from the second device, a second broadcast message. The first device may authenticate the second device based on at least a second portion of the pairing code in the second broadcast message. The first device may establish a wireless peer-to-peer communication channel with the second device, and receive, from the second device, a second handshake code via the wireless peer-to-peer communication channel. The first device may authorize the second party to engage in an offline interaction with the first party based on the first handshake code and the second handshake code.
