In this paper, the state diagrams and steady-state balance equations for two kinds of open queuing network models are presented. The first model comprises a network of single queues with single servers, while the second model comprises multiple servers for single queues. State diagrams are drawn for (2,3) queuing networks with (i) single servers and (ii) multiple servers. Steady-state balance e...

The support of real-time traffic in class-based IP networks requires the reservation of resources in all the links along the end-to-end paths through appropriate queuing and forwarding mechanisms. This resource allocation should be accompanied by appropriate admission control procedures in order to guarantee that newly admitted real-time traffic flows do not cause any violation to the Quality o...

Service reliability in a distributed queuing system can be assessed by means of the probability of successfully serving queued tasks in a heterogeneous network of nodes. Moreover, randomness in delays imposed by the communication medium adds to the uncertainties in the shared information among these faulty nodes, which complicates the dynamics of the queuing system. A novel approach based on st...

Broadband-ISDN (BISDN) will be implemented using Asynchronous Transfer Mode (ATM). This is prompted by the need to handle a variety of types of services, with diverse demands on the network in terms of the bit rate required and their holding times. Continuous as well as variable bit rates will be serviced. Services with holding times in the range of milliseconds to hours will be admitted to the...

Embedded applications have become more and more complex, increasing the demands on the communication network. For reasons such as safety and usability, there are real-time constraints that must be met. Also, to offer high performance, network protocols should offer efficient user services aimed at specific types of communication. At the same time, it is desirable to design and implement embedde...

Most of the real life multi server queuing systems have heterogeneous servers which means each service rates are different than each other. Analysis of such queuing system plays important role to improve performance. In this report, I have summarized analysis of heterogeneous multi server queuing system which has a finite and an infinite buffer. Average waiting time and average queue length are...

In this paper, we develop a ltering theory for deterministic traac regulation and service guarantees under the (min; +)-algebra. We show that traac regulators that generate f-upper constrained outputs can be implemented optimally by a linear time invariant lter with the impulse response f under the (min; +)-algebra, where f is the subadditive closure deened in the paper. Analogous to the classi...

In next generation wireless networks such as 4GLTE and WiMax, the demand for high data rates, the scarcity of wireless resources and the time varying channel conditions has led to the adoption of more sophisticated and robust techniques in PHY such as orthogonal frequency division multiplexing (OFDM) and the corresponding access technique known as orthogonal frequency division multiplexing acce...

This study aims to develop a planning model for the deployment of flood emergency response materials under stochastic demands. For ease modeling, deterministic demand is first proposed, from which further extended. These models are used determine allocation transport truck routes and distribution stockpiled sites. The formulated as multiple integer network flow problems with special side constr...

  Network and processing overhead associated with web services is a significant challenge to its performance. As a result, web service providers often announce a service level agreement. This ensures that consumers, who pay for the service, can get the service at a given quality level. In this paper, we study the competition between two providers offering functionally the same web services, whe...
