One goal in certain classes of networked multimedia applications, such as full-feedback remote control, is to provide end-to-end guarantees. To achieve guarantees, all resources along the path(s) between the resource(s) and sink(s) must be controlled. Resource availability is checked by the admission service during the call establishment phase. Current admission services control only network re...

The Internet backbone of many corporations carries two kinds of traffic: urgent and delayable. Shifting some traffic from peak periods to valleys reduces capacity requirements. We consider the case of managing the delayable traffic by an admission control (AC) system. AC gets link utilization feedback every τ seconds. Delayable opt-in sources obtain permission from AC to transmit for up to τ se...

We analyse a cell of Cognitive Radio Network ( $CRN$ ) as the multiline queueing system supplying service to two Markovian arrival flows users. Primary (or licensed) users called High Priority Users notation="LaTeX">$HPU\text{s}$ have...

This paper comes up with a mechanism of optimal joint call admission control based on different service types. Considering practical wireless transmission environment, it divides the heterogeneous wireless network into several areas and also defines the peak rates that its users could get in each area. The process of call admission control is modeled into a semi-Markov process for the two typic...
