Abstract :
This paper innovatively proposes a solution to choose an energy efficiency radio-over-fiber (RoF) distributed antenna system (DAS) based wireless sensor network (WSN) by modelling the total power consumption of the network. It is shown that for a given power consumption value, the tradeoff among the number of remote access units (RAUs), the number of MIMO antennas and the number of hops must be taken into account. And our quantified results provide basis for selecting a suitable RoF DAS based WSN with an appropriate number of hops before future actual deployment.
