Enhancement of Call Admission Control Schemes in LTE - Networks

M. Sreenadh Reddy, M. Haranadh Reddy, A. Uday Kiran

Abstract: Call admission control (CAC) theme encompasses a major impact in reassuring QoS numerous users with various QoS Requirements in 4G networks. because of the massive users and their frequent demands, it's necessary to use the restricted network resources that guarantee the eminent customary quality of service (QoS). Recently, the reservation-based theme and information measure degradation schemes were planned with the aim to produce effective use of network resources and assure QoS necessities to admitted calls. Consequently, many schemes are planned to manage resources whereas making certain QoS to wireless applications. These algorithms square measure classified into CAC with Pre-emption, Resource Reservation (RR), Resource Degradation (RD), Delay Awareness (DA) or Channel Awareness (CA). Simulation results show that the planned theme considerably outperforms the reservation-based theme and information measure degradation schemes in terms of admitting several calls and guaranteeing QoS to any or all the traffic varieties within the network.

Keywords: Call admission control CAC, Quality of service QoS, Resource Reservation RR, Resource Degradation RD, Delay Awareness DA or Channel Awareness CA
