Call admission control is a key element for providing quality of service (QoS) in mobile wireless networks. Traditional admission control schemes only address call-level QoS guarantee because of the underlying circuit-based network architecture. In contrast, emerging wireless technologies such as 3G and 4G tend to be packet-switched rather than circuit-switched because the packet-based architec...

InWiMAXCall admission control (CAC) plays a vital role in providing the desired quality of service.It is such a provisioning strategy to limit the number of incoming connections into the networks in order to reduce the network congestion and call dropping. Over the last few years, a significant number of call admission control (CAC) schemes have been anticipated for WiMAXnetwork. In this paper,...

We are given nodes in a communication network that request connections to other nodes. A central authority may accept or reject such right away, and once connection is established its duration unbounded edges cannot be used for connections; actions performed without knowledge of future requests, is, we consider an online setting. examine this so-called call admission problem tree networks. The ...

Support for real-time multimedia applications is becoming an essential requirement for packetswitched networks. In this work, we investigated how routing and admission control in uence the performance of packet-switched networks. We propose and evaluate the use of routing algorithms which take into account the constraints imposed by the admission control algorithms. Routing algorithms proposed ...

So the network aims at satisfying their demands without much degradation of quality in terms of call dropping and call blocking. It is possible by admission control algorithms and by optimizing the sharing and utilization of existing resources in an effective way. It improves the overall performance of the network system. This paper addresses different Quality of Service (QoS) requirements of t...

The main goal ofNew Radio 5G (NR) mobile technology is to support three generic service categories, each with very specific requirements. first category enhanced Mobile Broadband (eMBB), the second relates massive Machine-Type Communications (mMTC), and third ultra-Reliable Low Latency (URLLC). slicing of radio part network access has greatly contributed emergence these categories different qua...

Many audio and video \play-back" applications require that all of their packets arrive within their play-back time. Furthermore, the applications with the hard real-time requirements also require guaranteed service from the network. These applications are covered under the \Guaranteed Quality of Service" speciications by the IETF. It guarantees that the packets will arrive within the guaranteed...
