Fuzzy Logic based Call Admission Control for Next Generation Wireless Networks.

Abstract

There is rapid growth and changes occurring in the field of wireless communication network (WCN) in recent days. Due to which the management and control of this WCN without decreasing the quality of service (QoS) has become a great problem. One of the major reasons for the decrease of QoS in WCN is increase in the call blocking probability. A Fuzzy Logic (FL) based Call Admission Control (CAC) method is proposed to address this problem in the work carried out. In this scheme primarily, the total bandwidth is partitioned into three parts viz. platinum class, gold class and silver class. These divisions are mainly based on user preferences. So to cleverly keep the blocking probability as low as possible, a FL based CAC is being implemented in platinum class for the available bandwidth. Simulation results show that the proposed FL based CAC reduces the call blocking probability to a maximum extent.
