Named Data Networking (NDN) is one of the most promising future Internet architectures, which supports communications based on content names but not the content locations. Clients can retrieve content only by sending an Interest packet, which includes the content name. However, independent Interest packets will cause heavy loads on the routers, particularly in the Internet of Things (IoT) scenarios which will induce huge number of small-sized content exchanges. The proposed scheme enables clients to retrieve many different contents by sending an aggregated Interest packet. In addition, the Data packet can also be aggregated by the intermediate routers to improve the efficiency of NDN communications.
