Performance analysis of a fuzzy logic based adaptive call admission control over heterogeneous wireless networks

This paper propose a novel call admission control (CAC) scheme that considers real-time and non-real-time nature of a call before allocating resources for its progress in a network. The scheme accumulates the benefits of different CAC schemes for best optimization of the available resources. It has combined the three major schemes- reserve guard channel, buffer based and prioritization. Application of fuzzy logic made the scheme adaptive by dynamic control of the threshold resource parameters using fuzzy logic. Simulation results show that the scheme outperforms the existing CAC schemes in terms of QoS.
