An Enhanced Sinr-based Call Admission Control in 3g Networks
This paper presents the signal-to-interference plus noise ratio (SINR)-based call admission control (CAC) as an effective technique that guarantees signal quality for admitted users. We propose a CAC model that admits users as long as the SINR exceeds a threshold ( th SINR ). To reduce blocking, we ensure that the threshold level is maintained at a lower bound ( th lb SINR − ), convenient to ke...
متن کاملCall Admission Control performance model for Beyond 3G Wireless Networks
The Next Generation Wireless Networks (NGWN) will be heterogeneous in nature where the different Radio Access Technologies (RATs) operate together .The mobile terminals operating in this heterogeneous environment will have different QoS requirements to be handled by the system. These QoS requirements are determined by a set of QoS parameters. The radio resource management is one of the key chal...
متن کاملEfficient call admission control for 3G networks chernoff-bound based CAC
In the recent years the mobile telecommunication networks have gone through on a big development. The services of the systems have been extended very quickly, such as the number of the subscribers. The various multimedia and Internet systems have become quickly the part of our life. This phenomenon takes effect on mobile communication, too. The third-generation mobile networks could be the solu...
متن کاملA QoS Provisioning Recurrent Neural Network based Call Admission Control for beyond 3G Networks
The Call admission control (CAC) is one of the Radio Resource Management (RRM) techniques that plays influential role in ensuring the desired Quality of Service (QoS) to the users and applications in next generation networks. This paper proposes a fuzzy neural approach for making the call admission control decision in multi class traffic based Next Generation Wireless Networks (NGWN). The propo...
متن کاملQoS-Aware SINR-based Call Blocking Evaluation in Cellular Networks with 3G Interface
A Quality of service (QoS)-aware signal to interference and noise ratio (SINR)-based blocking probability model is simulated in this paper to evaluate the performance of networks with third generation (3G) interface. To arrive at a suitable model, we set a relatively low SINR threshold value ( th SINR ), which results in the admission of more users into the system. But this in turn yields an in...
