INADS: In-network aggregation and distribution of IoT data subscription in ICN
Lijun Dong, Guoqiang Wang · 2017
The subscription and notification communication pattern is commonly used in IoT applications, accompanied with notification conditions, for consumers to get notified of the interested information. The existing pub/sub solutions do not suit the IoT data subscription and notification triggered by the value change over the time. The paper proposes the in-network aggregation and distribution of conditional IoT subscription solution (INADS) for Information Centric Networking (ICN), which has been considered as one of the promising candidates for future IoT 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 IoT devices' limited power. On the other hand, the bandwidth usage in transmitting the subscription messages and redundant notification messages is dramatically decreased.
