Wireless networking technologies for realizing highly reliable socio-CA's communications
Development of system-level simulator to assess the reliability of socio-CA's communications
Socio-CAs are used for fulfilling tasks that need interaction with human. So, many people may gather or walk around a socio-CA, and it causes disruption of wireless communication that the socio-CA conducts. For supporting socio-CA's teleoperators who are not experts of wireless communications, this sub-theme develops a system-level simulator of socio-CA's communications to assess whether socio-CAs can work well, and how much is wireless equipment necessary to properly operate the socio-CAs.
Development of wireless networking technologies to realize highly reliable socio-CA's operation
In extremely severe situations, such that there are many people nearby a socio-CA, it is impossible to perfectly avoid the disruption of the socio-CA's communications, On the other hand, it is quite important to avoid such disruption as little as possible to realize high reliability of the CA's operation. Hence, this sub-theme studies on networking technologies to effectively utilize multiple wireless networks to realize robust socio-CA's communications for a large number of socio-CAs and people, and against the changes of communication environment caused by movement of socio-CAs and people. The research topics are as follows.
* Efficiently utilize multiple wireless networks such as local 5G and wireless LAN (Wi-Fi) by selecting a suitable network according to the property of socio-CA's traffic such as data amount and allowable transmission delay.
* Change network connection before running out of radio resources required for accommodating socio-CA's wireless communications.
* Transmit traffic data over multiple wireless networks in parallel to safely deliver the data even though either of networks is temporally unstable.
