| Abstract(in English) | This paper proposes a communication method for collecting image data in a Wi-Fi multi-hop IoT net- work, assuming self-sustaining power supply. Specifically, the IoT network consists of a large number of sensor nodes and a single sink node that collects image data as well as sensor data. The sensor node wakes up at regular intervals and executes the operation cycle. The operation cycle consists of four temporal slots. In the first slot, each sensor node recognizes its adjacent sensor nodes and synchronizes its clock. In the second slot, in addition to the sensor data, each sensor nodes sends its status information such as remaining battery power (push manner). In the third slot, the sink node calculates scheduling and routes for image data transfer based on the information collected from the sensor nodes, and sends the result to the sensor nodes (SDN manner). In the fourth slot, the requested sensor node sends image data along with the specified route at the specified start time (pull manner).The proposed method is implemented on an emulator that emulates wireless communication and measured the basic performance. As a result, it is confirmed that it is possible to reduce the variation of the remaining battery power and to make the sensor node survive longer. |
