In this paper, we address the problem of power control in wireless queueing networks. We consider a discrete time (slotted) wireless system of single link. Data arrive in packets according to a Bernoulli process of rate λ. A simple ARQ (send and wait) retransmission policy is used for the transmission of packets. The control parameter in this system is the transmission power of a packet, which ...

A Starlite-like switching architecture for ATM applications is examined in this paper. The switching architecture consists primarily of a Batcher sorting network and a Banyan switching network. A performance evaluation is done using both analysis and simulation. A discrete time queueing analysis is utilized due to the slotted nature of the system. Cells that are unable to make it through the sy...

There are some problems with estimating the time required for the manufacturing process of products, especially when there is a variable serving time, like control stage. These problems will cause overestimation of process time. Layout constraints, reworking constraints and inflexible product schedule in multi product lines need a precise planning to reduce volume in particular situation of lin...

In this paper, we establish a discrete time Geom/G/1 queue with setup-close delay-close down based on operation mechanisms with Switch Virtual Channels (SVC). Different from conventional intricate and time consuming imbedded Markov renewal processes, we use the factorization principle of discrete time queues with general vacation to analyze the response time, connection establishment ratio, ope...

In this paper we present an analysis of the discrete-time Geo/D/N − ∞ queue. This model has been recently applied as an asymptotic model in performance studies of various modern telecommunication systems. The distribution of the number of customers at arbitrary discrete time instants and the corresponding arrival distribution are derived. Using these results the waiting time distribution is obt...
