This SpringerBrief explains how to leverage mobile users' social
relationships to improve the interactions of mobile devices in mobile
networks. It develops a social group utility maximization (SGUM)
framework that captures diverse social ties of mobile users and diverse
physical coupling of mobile devices. Key topics include random access
control, power control, spectrum access, and location privacy. This
brief also investigates SGUM-based power control game and random access
control game, for which it establishes the socially-aware Nash
equilibrium (SNE). It then examines the critical SGUM-based spectrum
access game, and pseudonym change game for personalized location
privacy. The authors propose future work on extending the SGUM framework
to negative social ties, to demonstrate relevance to security
applications and span the continuum between zero-sum game (ZSG) and
non-cooperative game (NCG). Social Group Utility Maximization targets
researchers and professionals working on mobile networks and social
networks. Advanced-level students in electrical engineering and computer
science will also find this material useful for their related courses.
