Queueing theory offers a large variety of techniques that can be used in performance modelling of computer systems and data communication networks. The diversity of assumptions causes that the numerical results, obtained for the same system but by means of different techniques, can often be numerically very different. The project is aimed at finding common denominators for numerical results obt...

Remote access to dynamically changing information elements is a required functionality for various network services, including routing and instances of context-sensitive networking. Three fundamentally different strategies for such access are investigated in this paper: (1) a reactive approach initiated by the requesting entity, and two versions of proactive approaches in which the entity that ...

Queueing Theory finds its applications in various versatile domains in modern world. We investigate yet another application of Queueing Theory In modeling of MANET. More specifically, we study the ‘Queueing Network Mobility Model’of Mobile Ad-Hoc Networks (MANET), its applications and limitations. Motivated by its simplicity and successful performance, we use Queueing Network Analyzer (QNA) to ...

Classically, scheduling research in artificial intelligence has concentrated on the combinatorial challenges arising in a large, static domain where the set of jobs, resource capacities, and other problem parameters are known with certainty and do not change. In contrast, queueing theory has focused primarily on the stochastic arrival and resource requirements of new jobs, de-emphasizing the co...

Queueing theory is concerned with the mathematical analysis of systems that provide service to random demands. This theory has many application areas (e.g., industrial engineering, electrical engineering, computer science, telecommunications, and operations management). Consequently, the terminology and notation, while often intuitively sensible, are not always consistent. The mathematical theo...

Problems related to patient scheduling and queueing in emergency departments are gaining increasing attention theory, the fields of operations research healthcare services, practice. This paper aims provide an extensive review studies addressing queueing-related problems explicitly departments. We have reviewed 229 articles books spanning seven decades sought organize information they contain a...
