Call Setup Latency Analysis in SIP-Based Voice over WLANs

Sangheon Pack, Hojin Lee
2008 IEEE Communications Letters  
In this letter, we consider session initiation protocol (SIP)-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. Index Terms-Voice over WLANs, SIP, call setup latency.
