Call Admission Control under QoS Constraints Using NeuroEvolution of Topologies

چکیده
In this paper, we solve the call admission control (CAC) problem in a cellular network via a form of NeuroEvolution algorithm. The results are compared with Complete Sharing scheme, which allows all types of traffic to access all available channels at all time, and show that our proposed CAC scheme CN can reduce the hand off failure subject to several predefined Quality of Service (QoS) constraints: the handoff dropping probability (CDR) and intra-class fairness are all guaranteed within the predefined constraints. Additionally, the numerical results shows that under the same handoff failure constraint, better fairness causes higher new setup calls blocking probabilities (CBR) and lower CDR, therefore the fairness and maximizing revenue are two opposite goals, and the fairness and CDR do not conflict with each other.

Dynamic Call Admission Control with Joint Connection-level and Packet-level QoS Support in Wireless Multimedia Networks
In this paper, we investigate joint provision of connection-level QoS (in terms of the new call blocking probability and the handoff dropping probability) and packet-level QoS (in terms of the delay and packet loss probability). A dynamic call admission control (CAC) scheme for realistic wireless multimedia VBR traffic is presented. The proposed CAC scheme can optimize the packet-level QoS unde...
متن کاملA Call Admission Control Scheme Using NeuroEvolution Algorithm in Cellular Networks
This paper proposes an approach for learning call admission control (CAC) policies in a cellular network that handles several classes of traffic with different resource requirements. The performance measures in cellular networks are long term revenue, utility, call blocking rate (CBR) and handoff failure rate (CDR). Reinforcement Learning (RL) can be used to provide the optimal solution, howeve...

متن کاملCall admission control schemes under generalized processor sharing scheduling
Provision of Quality-of-Service (QoS) guarantees is an important and challenging issue in the design of integrated-services packet networks. Call admission control is an integral part of the challenge and is closely related to other aspects of networks such as service models, scheduling disciplines, traffic characterization and QoS specification. In this paper we provide a theoretical framework...
