Query: Fair Airtime Allocation for Content Dissemination in WiFi-Direct-Based
  Mobile Social Networks   The vast penetration of smart mobile devices provides a unique opportunity to
make mobile social networking pervasive by leveraging the feature of
short-range wireless communication technologies (e.g. WiFi Direct). In this
paper, we study local content dissemination in WiFi-Direct-based mobile social
networks (MSNs). We propose a simple GO-coordinated dissemination strategy, as
WiFi Direct does not originally support content dissemination. Due to mobility
and the short transmission range, the duration of nodes in contact tends to be
limited and consequently they compete for the limited airtime to disseminate
their own data. Therefore, fair allocation of the limited airtime among the
nodes is required. We focus on fairness in content dissemination rate, which is
a key application-layer metric, rather than fairness in throughput or airtime
and formulate the allocation problem as a generalized Nash bargaining game
wherein the nodes bargain for a share of the limited airtime. The game is
proved to have a unique optimal solution, and an algorithm with low complexity
is designed to find the optimal solution. Furthermore, we propose a detailed
scheduling approach to implement the optimal solution. We also present
numerical results to evaluate the Nash bargaining based allocation and
scheduling.
