Figure 9.2-1 shows the concept of real time IoT information search using ICN smart routing scheme and In-
network data processing. In this case, the user wants to find the location of the lost child or elder person. He
submits an Interest packet requesting the person search processing. The interest packet contains the
following information.

• Person search processing request by processing name
• Targeted geometrical search area name
• Information of target person (Still picture, etc.) as an extended field of name
By receiving this Interest packet, the smart routing function of each node checks the face of each node to
forward based on the keyword such as geometrical search area and lost people search processing, and if
necessary send the interest to plural faces at a time. When the Interest approaches to the targeted area, it
is automatically spread to relevant nodes that cover the area, and finally the monitor cameras. Monitor
cameras received the Interest send back their images as Data packet to the network. Then the Data packet
receiving node checks whether the person search processing program is available on its node. If not available,
it forward the Data packet back to the face that the Interest packet came. On the other hand, when the
person search processing is available, the node analyses the data from a monitor camera with the targeted
person’s information. When the image fits, the node send back the “find” message with extracted image to
the requester. When the image does not fit, the node terminates the Data packet. By this mechanism, the
user can receive the service by sending just one Interest to the network. In the current IP, user himself must
find the locations of the monitor cameras in the targeted area, establishes many sessions with these cameras,
and apply the person search program on the collected data. Compared to this, new service scenario described
makes the operation much easier for the user to receive a service, and also considerable bandwidth saving
for image data transmission can be achieved.
