With the development and spread of IoT technology, various devices have been connected to networks. Some data generated from IoT devices depends on geographical location and time (Spatio-temporal Data, STD). For location-dependent applications, it is effective to spread and acquire STD at the location in real-time. Therefore, to aim for local production and consumption of STD, we have proposed the STD retention system using vehicles and evaluated its performance with STD consisting of a single packet. However, there are various types and sizes of STD such as sensing data, photos, video, and so on. To retain these STD efficiently, a transmission control method considering large-capacity data is necessary. Hence, in this paper, we propose a selective data transmission control method to realize large STD retention based on data completeness. Finally, we evaluated our proposed method using simulations. The simulation result clarifies that our proposed method can suppress packet collisions by reducing incomplete data transmission and retain large STD efficiently. |
