Abstract:
Big data architectures have transformed the way enterprises collect, store and analyze massive amounts of spatio-temporal data from the mobile workforce. In this talk, I will present operators and systems for querying and managing such Mobile Big Data (MBD), that address challenges of performance, privacy, utility and network efficiency. I will start out by overviewing Anyplace, our Internet-based Indoor Navigation service that won several international research awards for its accuracy and utility. Particularly, I will discuss the challenges in prefetching and privacy-aware data processing of Indoor MBD (e.g., Wi-Fi and magnetic signals). My talk will be succeeded by a summary of Rayzit, which is an award-winning location-based crowd messaging service that allows a mobile crowd to instantly connect to its k Nearest Neighbors (kNN) as they move in space. I will particularly focus on Spitfire, which is a distributed algorithm that provides a scalable and high-performance All k Nearest Neighbor processing operator to Rayzit. I will then overview Spate, which is a novel spatio-temporal data processing and analytic system for telecommunication data (e.g., CDR and MR), which makes compression and decaying a first-class citizen. Finally, I will be concluding with an outlook to our current and future research agenda.
