Abstract

In this letter, we tackle the problem of competitive single antenna transmitters accessing a multiple antenna access point using a random access protocol. We show that the access point can help the system to reach a unique Stackelberg equilibrium and prevent network collapse due to the selfish nature of the transmitters.
