owlBIT: Orchestrating Wireless Transmissions for Launching Big Data Platforms in an Internet of Things Environment

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 network will greatly impact the shuffling process. Since IoT devices mostly rely on wireless network based on 802.11, providing proper throughput to big data computing system is an important challenge that needs to be address. In this paper, we argue that a cluster of IoT computers can support big data by considering the information fed by the big data applications. We propose a cross-layer framework that uses the application layer information to guide the packet scheduling at the link layer. We implement our system as an extension module in Hadoop-Yarn system. The experimental evaluation shows significant performance improvement.
