VoIP and Database Traffic Co-Existence Over IEEE 802.11b WLAN With Redundancy
This paper presents the findings of two experiments that were performed on the Redundancy in Wireless Connection Model (RiWC) using the 802.11b standard. The experiments were simulated using OPNET 11.5 Modeler software. The first was aimed at finding the maximum number of simultaneous Voice over Internet Protocol (VoIP) users the model would support under the G.711 and G.729 codec standards when the packetization interval was 10 milliseconds (ms). The second experiment examined the model's VoIP user capacity using the G.729 codec standard along with background traffic using the same packetization interval as in the first experiment.
