Abstract :
When two queues interact with each other, the delay of one queue depends on the behavior of the other queue. More specifically, the delay of one user depends on the access probability of the other user, since this probability controls the level of mutual interference in the network. In this sense, the delay of a given user can be limited by appropriately adjusting the access probability of the other user in the network, as investigated by several authors. In this paper we investigate the effects of spectral efficiency of the communication links on this optimization problem related to the access probability.
