With the development and spread of Internet of Things (IoT) technology, the number of devices connected to the Internet is increasing, and various kinds of data are now being generated from IoT devices. Some data generated from IoT devices depends on geographical location and time. We refer to such data as spatio-temporal data (STD). Since the “local production and consumption” of STD is effective for location-dependent applications, we have proposed a STD retention system using vehicles equipped with storage modules, computing resources, and short-range wireless communication equipment. In this previous system, each vehicle controls the data transmission probability based on the neighboring vehicle density in order to achieve effective data retention. However, since the overhead of beacon messages required for estimation of the neighboring vehicle density becomes a critical problem with the increase in the number of vehicles, thereby preventing the effective data retention. In this paper, we propose a new data transmission control method to realize effective and reliable STD retention without beacon. Simulation results showed that our proposed scheme can achieve effective data retention.

This paper presents the results of verification tests for the application of a 5th generation mobile communication system (5G) to an industrial robot control system, consisting of an industrial robot, a three-dimensional measurement sensor, and a robot controller. First, the configuration of the industrial robot control system to be used for testing was examined. Second, the 5G radio characteristics at two factories were measured. The radio interference to/from devices in operation in the factories and the human shield effect influencing the radio characteristics were also examined in these measurements. In factory automation, it is generally inevitable to spend a long time rearranging the components of the industrial robot control system. From the test results, it was confirmed that the time required could be greatly reduced by replacing wired communication lines with 5G capable systems.
