List-based redundancy control in crowd-based IoT

A coordinator device for use in a method for redundancy control in decentralized crowd-based data collection network architecture, where a crowd of user equipment 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,

• wherein the coordinator device exchanges data with the backend cloud infrastructure,
• wherein the backend cloud infrastructure is configured to:
• assign to each connected object an identifier ID and a freshness indicator, where 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, set 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,
• wherein the coordinator device comprises a processing circuit configured to:
• receive from the backend cloud infrastructure a list of ID's of at least one connected object for which the freshness indicator has the value of “fresh”, termed “fresh list”, and
• broadcast the fresh list to an area defined by the broadcasting range of the coordinator device.

A user equipment acting as collaborative IoT reader device for use in a method for redundancy control in decentralized crowd-based data collection network architecture, where a crowd of user equipment 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,

• wherein the user equipment exchanges data with the backend cloud infrastructure,
• wherein the backend cloud infrastructure is configured to:

• where the freshness indicator is a label having a value selected from one of “fresh” or “expired”,

• 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,
• wherein the user equipment comprises a processing circuit configured to:
• receive a list of ID's of at least one connected object for which the freshness indicator has the value of “fresh”, termed “fresh list” from a coordinator device,
• read the identifier ID's of the connected objects included in the fresh list, and
• exclude the data received from the connected objects contained in the fresh list from being transmitted to the backend cloud infrastructure.
