Wireless Networks and Games Theory

Dear Colleagues,

Game Theory is a fascinating tool with which to analyse the potential conflict of interest arising between independent rational agents when they strategically interact with each other. It has recently gained momentum to boost the utilisation of scarce radio resources (e.g., spectrum, energy, relay nodes, etc.) in a distributed fashion. Game players typically involve mobile nodes (i.e., relays and sources), User Equipment (UE), small-cell and macro-cell Radio Access Networks (RAN), primary and secondary cognitive radios, an attacker, a network security manager, etc. The strategy set can include, for example, deciding whether or not to turn on a radio interface, connect to a RAN, cooperate with other peers, etc. Utility functions need to be defined to help players assess their payoff from choosing any strategy. Nash Equilibrium can be applied to predict the strategic outcome of a game. Additionally, recent innovations in wireless communications, such as relaying and network coding, fundamentally rely on cooperation of players. Nonetheless, this cannot be taken for granted, since players naturally seek to maximise their own payoff. Proper mechanisms are needed to foster cooperation and discourage selfish behaviour. Finally, coalitional games can be employed in incidents in which players are allowed to form coalitions and, when profitable, pool their resources and improve their individual and group payoff.  

The topics of interest for this Special Issue include, but are not limited to, the following:

• Cooperative Communications
• Network Coding
• Small Cells
• Self-Organising Network (SON)
• Radio Resource Allocation
• Energy Efficiency
• Spectral Efficiency
• Trust Management
• Cognitive Radio
• Cybersecurity Game

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Games is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
