An End-to-End Measurement-Based Admission Control Policy for VoIP over Wireless Networks

In this paper, we present a new policy for admitting voice over IP (VoIP) sessions over wireless networks. Our proposed policy receives the admission information advertised by the VoIP gateway on the wired network, and uses it to decide whether a new VoIP session can be admitted or not. The proposed policy can be easily integrated with the current call admission control algorithms used in wireless networks. We show that implementing the proposed policy increases the number of successful VoIP sessions admitted to the access point polling list, thus improving the wireless network utilization.
