Abstract
A method for redundancy control is disclosed. CIoT reader devices act as collaborative IoT gateways for connected objects and collect received data from the connected objects and transmit the data to a backend cloud infrastructure. The method includes assigning to each connected object an identifier ID and a freshness indicator, where the freshness indicator is a label having a value of “fresh” or “expired”, upon receiving data from at least one connected object, setting the freshness indicator to “fresh” for each respective connected object, wherein for each connected object the freshness indicator is configured to change to “expired” after a pre-determined period of time, and sending a message to coordinator device, the message containing a fresh list of ID's of connected objects for which the freshness indicator has “fresh”, wherein the coordinator device broadcasts the fresh list to CIoT reader devices within a broadcasting range of the coordinator device.
