VoIP Packet Delay in Single-Hop Ad-Hoc IEEE 802.11 Networks

This paper presents a joint VoIP / IEEE 802.11 model for ad-hoc networks. The model calculates the average number of collisions and the average packet delay. It is used to predict the impact of different configuration parameters (codec, packetization interval and datarate) in the performance of the network. The simulations validate the results obtained from the model and, additionally, expose that the distribution of the VoIP packet generation times of the different stations also modifies the average packet delay.
