Resource reservation or the other prioritization strategies adopted by Call Admission Control (CAC) schemes in wireless networks lead to unfair resource allocation to users belonging to different service classes (SCs) due to high divergence among the respective call blocking probabilities (CBPs). In this paper, we propose dynamic optimization of probabilistic CAC (P‐CAC) schemes to assure CAC fairness...
Resource reservation call admission control (CAC) schemes constitute an efficient solution for prioritizing high priority calls. Issues concerning fairness among calls arise during the implementation of CAC. In this paper, a new optimization model selecting the admission probability in thinning schemes is proposed to provide fairness in resource sharing among different input call stream flows. The...
In multiservice wireless networks, Call Admission Control (CAC) is essential to assure the quality of service requirements of the supported traffic. Call requests are usually classified into two different types: narrow-band and wide-band calls. In this paper, the probabilistic CAC scheme employed is extended through a game theoretic framework for resource allocation and price bargaining for the required...
The present paper investigates call admission control (CAC) over multiservice wireless - broadband over power line (BPL) networks. The CAC problem is examined not only as a decision process but, also, as a channel reallocation and QoS renegotiation process. A fast and effective CAC algorithm for BPL networks is proposed providing high network utilization, low blocking rate (BR) and fairness between...
Call admission control (CAC) is a significant radio resource management (RRM) function for quality of service (QoS) provisioning in wireless networks. Different CAC schemes have been proposed and evaluated, most of them under the call blocking probability (CBP) achieved. On the other hand, CAC problem in multiclass wireless networks should not only be evaluated under the CBP achieved for every service...
In wireless communications networks with multiple service classes (SCs) of calls, call admission control (CAC) schemes is an essential radio resource management (RRM) function for networks consistency. Apart from the calculation of the call blocking probability (CBP) appropriate criteria and metrics should be considered to evaluate the efficiency of various schemes. Fairness among different services...
