Simulation of Endpoint Based Call Admission Control Using Retransmission Timer

This paper demonstrates the elementary and basic functioning, noteworthy limitations of the existing scenario, the proposed scheme for Endpoint based Call Admission Control for the Voice over Internet Protocol over IEEE 802.11 Wireless Local Area Network for removing the existing issues and flaws, and it´s implementation for proving its necessity as well as importance in the real time scenario. According to the results obtained, the proposed scheme for Call Admission Control is found more efficient, reliable, improved in terms of Quality of Service, overcoming the flaws of the present scenario, and delivering the effective test results, when it was being evaluated on experimental test bed, with the added functionality of Retransmission Timer as a main component.
