Providing quality of service (QoS), in particular meeting the data rate and packet delay constraints of real-time data users, is one of the requirements in emerging high-speed data networks. Thisâ€¦ (More)

We consider the model where N queues (users) are served in discrete time by a generalized switch. The switch state is random, and it determines the set of possible service rate choices (schedulingâ€¦ (More)

We study a model of controlled queueing network, which operates and makes control decisions in discrete time. An underlying random network mode determines the set of available controls in each timeâ€¦ (More)

We consider a queueing system with multitype customers and flexible (multiskilled) servers that work in parallel. If Qi is the queue length of type i customers, this queue incurs cost at the rate ofâ€¦ (More)

The back-pressure algorithm is a well-known throughput-optimal algorithm. However, its delay performance may be quite poor even when the traffic load is not close to network capacity due to theâ€¦ (More)

We consider the following queueing system which arises as a model of a wireless link shared by multiple users. There is a nite number N of input ows served by a server. The system operates inâ€¦ (More)

We consider a single server system with N input flows. We assume that each flow has stationary increments and satisfies a sample path large deviation principle, and that the system is stable. Weâ€¦ (More)

We consider the following queuing system which arises as a model of a wireless link shared by multiple users+ There is a finite number N of input flows served by a server+ The system operates inâ€¦ (More)

We consider the following queueing system which arises as a model of a wireless link shared by multiple users. Multiple ows must be served by a \channel" (server). The channel capacity (service rate)â€¦ (More)

Self-optimization of the network, for the purposes of improving overall capacity and/or cell edge data rates, is an important objective for next generation cellular systems. We propose algorithmsâ€¦ (More)
