INADS: IN-NETWORK AGGREGATION AND DISTRIBUTION OF lOT DATA SUBSCRIPTION IN ICN

The subscription and notification communication pattern is commonly used in loT applications, accompanied with notification conditions, for consumers to get notified of the interested information. The existing pub/sub solutions do not suit the loT data subscription and notification triggered by the value change over the time. The paper proposes the in-network aggregation and distribution of conditional loT subscription solution (INADS) for Information Centric Networking (ICN), which has been considered as one of the promising candidates for future loT deployment. The new mechanism is proven to provide significant reduction in average number of notifications in both single and multiple producer scenarios, therefore save the loT devices' limited power. On the other hand, the bandwidth usage in transmitting the subscription messages and redundant notification messages is dramatically decreased.
