This paper studies a hierarchical distributed choice of retransmission probabilities in slotted aloha. In particular, we consider a wireless system composed of one central receiver and several selfish mobile users communicating via the slotted aloha protocol. The set of mobile users is split into two classes: leaders and followers. We then study the induced non-cooperative hierarchical game based...
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.
In this paper, we study the problem of multi-user channel selection in multi-channel wireless networks. Specifically, we study the case in which the autonomous users deploy delay-sensitive applications. Existing centralized approaches result in efficient allocations, but require intensive message exchanges among the users (i.e. they are not informationally efficient). Current distributed approaches...
