Wireless Transmission of Big Data: A Transmission Time Perspective
August 17, 2018 @ 4:00 pm - 5:00 pm
Co-sponsored by: UBC Okanagan
We are in the era of big data. Future wireless communication systems should effectively support various big data applications through the efficient transmission of large amounts of data. In this talk, we explore the wireless transmission of big data from a transmission time aspect. In particular, we investigate the transmission time of a large amount of data over wireless fading channel with adaptive modulation and coding (AMC). Unlike traditional transmission systems, the transmission time of AMC systems becomes a random variable, as the transmission rate varies with the fading channel condition. We derive the exact statistics of transmission time over various fading environment. We further extend the investigation to the cognitive environment. With interweave cognitive implementation, a secondary user transmits only if primary user does not occupy the channel. Therefore, secondary data transmission involves both transmission periods and waiting periods. We study the statistics of the resulting extended delivery time of secondary data transmission with adaptive transmission. These analytical results will greatly benefit the study of big data applications in wireless environment.
