Stability and asymptotic optimality of opportunistic schedulers in wireless systems
We investigate the scheduling of a common resource between several concurrent users when the feasible transmission rate of each user varies randomly over time. Time is slotted and users arrive and depart upon service ...
Heavy-traffic analysis of a multiple-phase network with discriminatory processor sharing
We analyze a generalization of the discriminatory processor-sharing (DPS) queue in a heavy-traffic setting. Customers present in the system are served simultaneously at rates controlled by a vector of weights. We assume ...
