| Outline of Final Research Achievements |
It is expected that the information and communication technology delivers fine-grained data about spatial information. An example scenario is that smart cars interact with drivers using such information, which could realize the society with no traffic congestion and accident. However, the data volume of spatial information can be huge; the communication network can be a bottleneck because of its limited capacity. Therefore, this study has established the model that represents importance of data and has proposed a control scheme that assigns communication and computational resource in accordance of the importance of data in terms of how easily the data can be estimated and replaced from and with other data. Considering the scenario mentioned above, our result has verified that the proposed scheme can reduce the retrieval latency of spatial information.
