Abstract

This paper analyzes voice transmission capacity on ad hoc networks by performing simulations related to delay and jitter. We evaluate the influence of QoS provision and mobility on the number of voice transmitting sources. Results show that the maximum number of voice transmissions can be increased when medium access time is reduced by means of a service differentiation mechanism applied to the MAC layer. Also, mobility and network load variations degrade the network capacity for voice transmission, mainly on multihop mobile networks.
