Abstract :
Unlike in IEEE 802.11, the CSMA/CA traffic conditions in IEEE 802.15.3 are typically unsaturated. This paper presents an extended analytical model based on Bianchi´s model in IEEE 802.11, by taking into account the device suspending events, unsaturated traffic conditions, as well as the effects of error-prone channels. Based on this model we re-derive a closed form expression of the average service time. The accuracy of the model is validated through extensive simulations. The analysis is also instructional for IEEE 802.11 networks under limited load.
