Multi-RAT network configuration for realizing highly reliable CA communications
Development of system-level simulator of CA's communications
This sub-theme develops a system-level simulator of CA's communications that can simulate a change of communication environment, and resultant changes of communication quality and required communication resources to accommodate a CA, especially in some extremely severe situations. Using this simulator, we will establish a method to calculate the suitable margin of communication resources to accommodate CAs stably.
Development of wireless networking technologies to realize highly reliable CA's operation
In extremely severe situations, such that there are many people nearby a CA, it is impossible to perfectly avoid the disruption of CA's communications, However, it is quite important to avoid such disruption as little as possible to realize highly reliable CA's operation. Hence, this sub-theme studies on technologies to configure wireless networks for realizing robust CA's communications against the changes of communication environment and flow of people, and CA's operation. The research topics are as follows.
* Selection of base station taking account for the margin of communication resources to accommodate CAs stably,
* Parallel transmission on multiple wireless networks (RATs),
* Selection of RAT taking account for the traffic pattern and the requirement on communication quality of CA's data flow.
