This paper investigates a new analytical model of a cell supporting adaptive traffic. A dynamic channel allocation scheme based on predefined bandwidth threshold values, which takes into account the signal power of incoming calls, is presented. A threshold value is set to limit the number of new connections to reduce the handoff dropping probability. Formula for performance characteristics e.g. blocking...
Universal Mobile Telecommunication System (UMTS) is a third generation mobile communication systems that supports wireless wideband multimedia applications. The objective of this paper is to present a new model for non-intrusive prediction of H.264 encoded video quality over UMTS networks and to illustrate their application to video quality monitoring and adaptation in mobile wireless streaming services...
This paper proposes a model for call admission control in the next generation wireless networks. It presents a prioritized call admission procedure using the combination of buffer and guard channel schemes applicable to the heterogeneous networks in general and wireless overlay network (WON) in particular call admission priority is given to the real time calls over the non-real time calls which are...
