Title: Isn’t It Odd that Flipping Coins Can Enable the Internet of Tomorrow?

Abstract: This talk will survey how various mathematical notions, including random coin flipping and linear algebra, can help design the Internet of tomorrow. It will introduce a new scheme for the unsourced multiple-access communication problem whereby devices sends data wirelessly to the cloud. The envisioned divide-and-conquer approach leverages recent advances in compressive sensing and introduces a novel error correction paradigm to produce an uncoordinated access scheme, along with a computationally efficient decoding algorithm. Within this framework, every active device first partitions its data into several sub-blocks and, subsequently, adds redundancy using a linear block code. The original messages are obtained by connecting pieces together using a low-complexity, tree-based algorithm. Hopefully, this will help attendees grow their understanding of possible applications for fundamental notions in math.
