Graph, Combinatorial Optimization for Wireless Networking

Speaker: Bo Bai

Time: Aug 29, 10:30am - 11:30am.

Location: Room 410, Teaching Center

Abstract:

With the rapid development of wireless communication technologies, it is believed that 5G will provide a unified wireless access solution to support not only the existing mobile communication traffic, but also many emerging wireless paradigms, such as D2D communications, V2X communications, Internet of things, sensor network, and wireless network control, etc. In this context, a key issue is how to efficiently share scare wireless resources with very low complexity so that the capacity can be greatly improved and latency can be significantly decreased. In diversified scenarios of future wireless networks, the wireless resource allocation can be modeled as discrete optimization problems, which are difficult to solve in general. In this talk, we will introduce graph theory and combinatorial optimization which are powerful tools for solving discrete optimization problems arose in wireless networking problems. This talk will introduce the application of combinatorial optimization techniques, such as matching theory and submodular optimization, to some typical wireless resource allocation problems, including subcarrier allocation in OFDMA systems, multi-flow relaying systems, D2D networks with two-way relaying, and wireless caching.
