Abstract: As spectrum sharing matures, usage conflict situations (e.g., harmful interference) remain a common concern. To deal with the challenges associated with conflict situations, multiple solutions have been proposed. Examples of approaches to mitigate conflict situations include the creation of exclusion and coordination zones, the development of spectrum coordinators (e.g., SAS), or the implementation of sensing-based mechanisms. Nonetheless, most of these solutions are designed as “one-size-fits-all” or global solutions. In this paper, we propose a local analysis of conflict situations in spectrum sharing settings through the design, development, and deployment of polycentric and self-governance systems. We have created a multi-tiered spectrum sharing model to analyze such systems using Agent-Based Modeling, Common-Pool Resource frameworks, and the core definitions of Radio Environment Maps (REMs).

Biography

Anant Sahai did his undergraduate work in EECS at UC Berkeley, and then went to MIT as a graduate student studying Electrical Engineering and Computer Science (Course 6 in MIT-speak). After graduating with his PhD, and before joining the Berkeley faculty, he was on the theoretical/algorithmic side of a team at the startup Enuvis, Inc. developing new adaptive software radio techniques for GPS in very low SNR environments (such as those encountered indoors in urban areas).He currently serves also as faculty adviser to UC Berkeley’s chapter of Eta Kappa Nu. He has previously served as the Treasurer for the IEEE Information Theory Society.

His research interests span information theory, decentralized control, machine learning, and wireless communication — with a particular interest at the intersections of these fields. Within wireless communication, he is particularly interested in Spectrum Sharing and Cognitive Radio, very-low-latency ultra-reliable wireless communication protocols for the Internet Of Things, and how agents could learn how to communicate with each other without the need for heavy-handed standards. Within control, he is interested in decentralized control and how agents could learn how to cooperate and interact with unknown environments. He is also interested in the foundations of machine learning, particularly as it pertains to why overparameterized models do or do not work.
