IoT Network


The Internet of Things (IoT), which extracts useful information for people's lives by collecting and analyzing sensing data measured by sensors installed in various locations and smartphones owned by various people, is attracting attention. Therefore, network control technologies to efficiently and cost-effectively transfer and analyze the data generated from time to time by a vast number of sensors are becoming increasingly important.

It is also expected to utilize autonomously moving devices such as mobile terminals and drones to distribute content and rescue victims during disasters.

Therefore, we are conducting research on control technologies of IoT networks with focusing on the following themes.

Delivery and Caching of IoT Data Using Information-Centric Networking

While various usage patterns can be envisioned for the IoT, one promising usage pattern is for users to specify location and sensing data conditions, and then collect data that matches those conditions. However, existing networks communicate based on location, so it is necessary to create a database of the location of data that matches the required conditions in advance.

On the other hand, the use of Information-Centric Networking (ICN) eliminates the need to create a database in advance, since request packets can be forwarded using the request conditions as names. Also, by utilizing router caches, it is possible to reuse aggregated data that matches the request conditions.

Therefore, our laboratory is engaged in research on efficient forwarding and cache control of IoT data using ICN.
