Query: Distributed Association and Relaying with Fairness in Millimeter Wave
  Networks   Millimeter wave (mmWave) systems are emerging as an essential technology to
enable extremely high data rate wireless communications. The main limiting
factors of mmWave systems are blockage (high penetration loss) and deafness
(misalignment between the beams of the transmitter and receiver). To alleviate
these problems, it is imperative to incorporate efficient association and
relaying between terminals and access points. Unfortunately, the existing
association techniques are designed for the traditional interference-limited
networks, and thus are highly suboptimal for mmWave communications due to
narrow-beam operations and the resulting non-negligible interference-free
behavior. This paper introduces a distributed approach that solves the joint
association and relaying problem in mmWave networks considering the load
balancing at access points. The problem is posed as a novel stochastic
optimization problem, which is solved by distributed auction algorithms where
the clients and relays act asynchronously to achieve optimal
client-relay-access point association. It is shown that the algorithms provably
converge to a solution that maximizes the aggregate logarithmic utility within
a desired bound. Numerical results allow to quantify the performance
enhancements introduced by the relays, and the substantial improvements of the
network throughput and fairness among the clients by the proposed association
method as compared to standard approaches. It is concluded that mmWave
communications with proper association and relaying mechanisms can support
extremely high data rates, connection reliability, and fairness among the
clients.
