Publication number: EP3419217A1
Title: NETWORK OF NODES AND METHOD OF OPERATION
Abstract: A network (200) of nodes is a wireless network (200) in which data is wirelessly transmitted between nodes (202). At least some of the nodes (202) have a transceiver for transmitting and receiving data packets and data storage for storing a database (300, 410). At least some of the nodes (202) are arranged such that if a node (202) generates its own new data element, the node (202) updates its own stored database (300, 410) with the data element, and transmits the data element to at least one other node (202); and if a node (202) receives a data element transmitted by another node (202), the node (202) updates its own database (300, 410) with the received data element. The database (300, 410) stored in each node (202) is in the form of a blockchain.

number: 5
text: A method of operating a network of nodes, wherein the network is a wireless network in which data is wirelessly transmitted between nodes, the method comprising storing a new data element in a database at at least some of the nodes, wherein:
number: 6
text: A method according to claim 5, wherein at least one node comprises a sensor, wherein the sensor takes a measurement and produces a data element corresponding to the measurement.
number: 7
text: A method according to claim 5 or claim 6, wherein the network is a mesh network.
number: 8
text: A method according to any of claims 5 to 7, wherein the network is a Low Rate Wireless Personal Area Network LR-WPAN network.
