We study the problem of optimally controlling the use of sleep states in an energy-aware M/G/1 queue. In our model, we consider a family of policies where the server upon becoming idle can wait for a random period before entering, potentially randoml

We analyze an energy-aware M X /G/1 queue under LAS scheduling with a setup delay and an idle timer that controls the delay before the server enters a sleep state. Through a classical busy period analysis, the expression for the mean conditional dela

We consider optimal energy-aware load balancing of elastic downlink data traffic inside a macrocell with multiple small cells within its coverage area. The system is modeled as a set of parallel queues. In particular, the model of the small cell incl

We explore the performance of different resource allocation schemes for transferring elastic traffic in a cellular network that is either overlaid or underlaid with D2D traffic. To this end, we model a single cell during uplink transmissions and join

We consider the optimal energy-aware control of a single server with batch arrivals and applying the SRPT scheduling rule. The server is modeled as an M X ∕ G ∕ 1 queue with a particular control policy that puts the server to a sleep mode to save

Opportunistic scheduling in wireless cellular systems utilizes random channel quality variations in time by favoring the users with good channel conditions. However, the success of such schedulers is heavily depending on the accuracy of the available

We consider the optimal opportunistic scheduling problem for downlink data traffic in a wireless cell with time-varying channels. The scheduler itself operates at a very fast time scale of milliseconds, but the objective function is related to minimi

We study the intercell coordination problem between two interfering cells combined with dynamic TDD serving elastic data traffic. We model the system at the so-called flow level, where the number of flows varies dynamically and each flow has a random

We study the optimal control of sleep states in an energy-aware M/G/1-FIFO queue. Two families of policies are considered, referred to as randomized and sequential policies. Under a randomized policy, the server upon becoming idle can wait for a rand

Despite the extensive literature on energy efficient control mechanisms for servers, only few studies address the processor sharing discipline. We study the energy-performance trade-off in an energy-aware M X / G / 1-PS system using two popular cost
