(English Abstract)
Due to the rapid development of Internet of Things (IoT) technologies, large volumes of traffic data are generated from IoT sensors. One of the crucial applications is to answer top-K queries over data stream from IoT devices. In this paper, we extended the existing temporal count-min sketches in a distributed mode: CM-Sketch on sliding window (CMSS) and Exponential-CM Sketch (ECM). These two techniques are implemented on a Spark engine and utilized for answering the approximate top-k query processing over taxi trip dataset. Our experimental results shows that CMSS performs better than ECM in terms of the memory consumption and execution time, whereas ECM produce more accurate results than CMSS.
