The Affection of MAC Protocols to Energy Consumption in the UWB-Ad hoc System
Energy is the vital source for the UWB-Ad hoc system. For the characteristics of UWB-Ad hoc system, it has some particular requests to the MAC layer. Accordingly, it is necessary to find out the affection of MAC protocols to the performance of UWB-Ad hoc system. In this paper, kinds of MAC protocols that are all rate-controlled were studied. And performance curves were gotten. Also, a general model of the energy consumption was set up, which was the foremost contribution of this paper. The conception of average signal-to-interference-and-noise-ratio and two variables of energy consumption degree and capability were brought forward to give the measurement of QoS guarantee. Mass simulations proved the model and QoS guarantee sufficiently.
