Enabling Technologies for Green Radio-over-Fiber Distributed Antenna System Based Wireless Sensor Network

Novel enabling technologies from physical layer to Medium Access Control (MAC) layer are proposed to provide energy efficient Radio-over-Fiber ( RoF ) Distributed Antenna System (DAS) based Wireless Sensor Networks (WSN). The power consumption performance of the net-work is evaluated in terms of the total network power consumption based on the proposed power consumption models from the physical layer. The results illustrate that for a given power consumption value, the tradeoff among the number of Remote Access Units (RAUs ), the number of Multiple-Input Multiple-Output (MIMO) antennas and the number of hops must be taken into account. In order to efficiently reduce the total network power consumption, we also proposed a solution from the MAC layer using a sleep-aware MAC protocol, which can dynamically centralized control MIMO antennas to operate in a sleep mode. The pro-posed enabling technologies provide basis for selecting suitable RoF DAS based WSN and effectively reduce the power consumption.
