Abstract: Both mobile networks and social networks are projected to continue growing rapidly in the foreseeable future. A salient feature of mobile networks is that mobile devices are carried and operated by human beings. With this insight, we develop a social group utility maximization (SGUM) game framework that takes into account both social coupling and physical coupling among mobile users. Under the SGUM framework, each user aims to maximize its social group utility, defined as the weighted sum of the individual utilities of the users that have social ties with it. One distinctive merit of the SGUM framework is that it provides a unifying platform to capture complex social structure among mobile users, consisting of diverse “positive” and “negative” social ties, and hence it offers rich flexibility in modeling and understanding the rich continuum from zero-sum game (ZSG) to non-cooperative game (NCG) to network utility maximization (NUM) - traditionally disjoint paradigms for network management. We will also touch upon related privacy and security issues.

Junshan Zhang received his Ph.D. degree from the School of ECE at Purdue University in 2000. He joined the School of ECEE at Arizona State University in August 2000, where he has been Professor since 2010. His interests include cyber-physical systems, communications networks, and network science. His current research focuses on fundamental problems in information networks and energy networks, including modeling and optimization for smart grid, network optimization/control, mobile social networks, crowdsourcing, cognitive radio, and network information theory.
Prof. Zhang is a fellow of the IEEE, and a recipient of the ONR Young Investigator Award in 2005 and the NSF CAREER award in 2003. He received the Outstanding Research Award from the IEEE Phoenix Section in 2003. He co-authored two papers that won the Best Paper Runner-up Award of IEEE INFOCOM 2009 and IEEE INFOCOM 2014, and a paper that won IEEE ICC 2008 Best Paper Award. He was TPC co-chair for a number of major conferences in communication networks, including INFOCOM 2012, WICON 2008 and IPCCC'06, and TPC vice chair for ICCCN'06. He was the general chair for IEEE Communication Theory Workshop 2007. He was an Associate Editor for IEEE Transactions on Wireless Communications, an editor for the Computer Network journal and an editor IEEE Wireless Communication Magazine. He is currently serving as a senior editor for IEEE/ACM Transactions on Networking and an editor for IEEE Network Magazine. He is a Distinguished Lecturer of the IEEE Communications Society. |
