Dr. Bo Sheng gave a talk in Room #109 in Mingli Builiding of the school on Apr. 25, 2018. The title of his talk is “Orchestrating Wireless Transmissions for Launching Big Data Platforms in an Internet of Things Environment”. The talk was hosted by Professor Genlin Ji. Dr. Sheng is an Associate Professor in the Department of Computer Science at University of Massachusetts Boston. He was the chair professor of the school of Computer Science and Technology.
The emergence of Edge Computing and the success of Internet of Thing and (IoT) has tremendously changed the way we think about data computing. With edge devices changing from data producer to both data producer and consumer, the chance for processing large data sets with Big Data on a cloud of IoT devices is more realistic. In Big Data systems such as Hadoop-Yarn, Spark, Pig, etc., the shuffling stage is by far the most dominant source of network traffic. Unreliable performance of the network could greatly impact the shuffling process. Since IoT devices mostly rely on wireless networks such as 802.11, providing proper throughputs to big data computing system is an important challenge that needs to be addressed. In this work, they argue that a cluster of IoT computers can support big data by considering the information fed by the big data applications. They propose a cross-layer framework that uses the application layer information to guide the packet scheduling at the link layer. They implement our system as an extension module in Hadoop-Yarn system. The experimental evaluation shows significant performance improvement.
After the talk, Dr. Sheng discussed with the audiences and answered their questions kindly. The audiences got much inspiration from the talk and the discussion.
