Call Setup Latency Analysis in SIP-Based Voice over WLANs
Sangheon Pack, Hojin Lee · IEEE Communications Letters · 2008
In this letter, we consider session initiation protocol (SlP)-based voice over wireless local area networks (VoWLANs). We derive the analytical expression for the average call setup latency, and we observe the impact of the number of contending mobile nodes in a WLAN. Extensive simulation results are given to validate the analytical results.
