Claim 0:
1. A method for redundancy control in decentralized crowd-based data collection network architecture, wherein a crowd of user equipment, termed “CIoT reader devices”, act as collaborative IoT gateways for connected objects and collect received data from the connected objects and transmit at least some of the data to a backend cloud infrastructure,
the method, implemented by a computer circuit of the backend cloud infrastructure, comprising:
assigning to each connected object an identifier ID and a freshness indicator, wherein the freshness indicator is a label having a value selected from one of “fresh” or “expired”,
upon receiving data from at least one connected object, setting the freshness indicator to the value of “fresh” for each respective connected object,
wherein for each connected object the freshness indicator is configured to change its value to “expired” after expiry of a pre-determined period of time, and
sending a message to at least one coordinator device, the message containing a list of ID's of at least one connected object for which the freshness indicator has the value of “fresh”, termed “fresh list”, wherein the coordinator device is configured to broadcast the fresh list to CIoT reader devices within a broadcasting range of the coordinator device, and wherein the CIoT reader devices are configured to exclude data from any connected object whose ID is appearing in the fresh list from being transmitted to the backend cloud infrastructure.
