Tills paper analyzes voice transmission capacity on ad hoc networks by performing simulations related to delay, jitter, loss rate, and consecutive losses. We evaluatethe influence of mobility and quality of service provisioning on the number of voice transnlitting sources. Another issue addressed in this paper is the effect of node density in voice transmission. Results show that we can achieve up to 22% of
improvement in the capacity of voice transmission when the medium access time is reduced by service differentiation on the MAC layer. Moreover, mobility and network load variations can degrade up to 60% the network capacity of voice transmission, mainly on multihop mobile networks.
