Internet of Things (IoT) applications produce large amount of sensor data. This data contains temporal information that can improve data analysis if utilized correctly. This talk is divided in three separate parts. Initially, we will discuss about examples of IoT applications and an overview of IoT platforms. Then, I will go deeper and show Freeze-Frame File System (FFFS), which allows temporal queries on demand. FFFS provides strong guarantees for users and efficiently handles temporal queries. Finally, we will talk about temporal caching. We effectively exploit temporal information in order to devise more sophisticated eviction policies for data analysis. Better utilization of cache leads to less I/O requests and less computations which improve the deployment of IoT platforms in terms of performance and costs.
