We consider a single server queueing system with two classes of jobs: eager jobs small sizes that require service to begin almost immediately upon arrival, and tolerant larger can wait for service. While blocking probability is the relevant performance metric class, class seeks minimize its mean sojourn time. In this article, we analyse each under dynamic scheduling policies, where both depends...

The retrial phenomenon occurs inherently in a wide range of queueing systems. majority models do not account for vacation. However, practice, systems undergo vacations maintenance or other reasons. In this study, we provide an in-depth analysis the many possible when Bernoulli are effect. Moreover, study outlines key principles and reviews relevant literature. framework queue with vacation has ...

In this paper we identify important characteristics of a fading/shadowing fading channel and present the work of measurement-based channel modeling for packet-level network queueing analysis. Our integration of wireless channel modeling and data queueing analysis at the packet-level provides a unique approach to study the eeect of various channel dynamics on high layer network performance, whic...

In modern networks serving real systems, there are a wide of variety of classes of messages. This results in the need for more sophisticated queueing policies. The desired queueing disciplines are expected to be able to consider all variables which are needed to handle messages appropriately. These variables include: diierent required service times, source traac chacteristics and quality of ser...
