We defined IoT device data that depends heavily on generation time and location as spatio-temporal data (STD). In the previous works, we have proposed the data retention system using vehicular networks to achieve the paradigm of “local production and consumption of STD.” The system can achieve to provide STDs quickly to users within a specific location by retaining the STD within the location, however, does not consider that each STD has different requirements for the data retention. In particular, the lifetime of the STD and the diffusion time to the whole location directly affect the performance of data retention. Therefore, we propose a dynamic transmission interval control method for the data retention system by considering the requirements. By the simulation evaluation, we found that our proposed method can satisfy the requirements of STD and maintain a high coverage rate in the location."}]},{"type":"Other","notation":[{"@value":"電子情報通信学会 ネットワークシステム研究会（NS）, 2019年3月4日-5日, 沖縄県宜野湾市,
