Many real systems such as production lines are modeled as queueing networks with finite buffers. In such a queueing model, blocking occurs if a customer attempts to enter the next queue whose buffer is full and not available. In this case, the customer is forced to wait until the next queue can be entered. General queueing networks with blocking do not have a product-form solution. Therefore, i...

In this paper, we investigate the problem of assignment of K identical servers to a set of N parallel queues in a time slotted queueing system. The connectivity of each queue to each server is randomly changing with time; each server can serve at most one queue and each queue can be served by at most one server per time slot. Such multi-server queueing systems were widely applied in modeling th...

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 ...
