Uma Análise da Capacidade de Transmissão de Voz em Redes Ad Hoc

Pedro Braconnot VellosoMarcelo G. RubinsteinOtto Carlos M. B. Duarte

This paper analyzes voice transmission capacity on ad hoc networks by performing simulations related to delay and jitter. We evaluate the influence of mobility and QoS provisioning on the number of voice transmitting sources. Results show that we can augment the capacity of voice transmission when medium access time is reduced by service differentiation on the MAC layer. Also, mobility and network load variations degrade the network capacity of voice transmission, mainly on multihop mobile networks, and jitter is the most sensitive parameter to these variations.
