Challenges in A New Data Explosion Environment

David Hung-Chang Du, Qwest Chair Professor
Department of Computer Science and Engineering
University of Minnesota, Minneapolis


The Internet today has grown to an enormously large scale. Devices large and small are connected globally from anywhere on the earth. With the rapid advancement of technology, we now also have cheap, small and smart devices with high computing power, powerful wireless communication capability and relatively large storage capacity. These devices are designed to improve our daily life by monitoring our environment, collecting critical data, and executing special instructions. These devices called sensors have gradually become an essential part of our Internet. They are embedded into physical systems (Cyber Physical Systems) and normal daily used objects (Internet of Things) to form a extremely large networks that we have ever witnessed. As a result, unprecedented amount of data are collected by these devices and are available via Internet. How to build such a system and manage and look for the desired information becomes a great challenge. In this talk, we will examine the challenges in this new computing and communication environment. These challenges include new data representations and models, data security and privacy issues, long-term data preservation methods, new data storage systems and even a new Internet architecture.
