RF Energy Harvesting using Wireless Sensor Network for Low Power Applications
The evolution of telecommunications systems emphasizes the importance of RF energy in the surroundings. This energy can be utilized for less power device namely wireless sensor network. The performance of small DC/RF converter is calculated in this paper in sequence to enslave the WSN performance for energy recovered. Specially to attain the performance in GSM band the efficient rectifier is achieved. Based on the selection of rectifying diode the design methodology works and causes the losses in rectifying antenna. By employing the slope method the advantageous performance is obtained in Advanced Design System (ADS) software. Implementing Schottky diodes in rectifier and voltage doubler HSMS 2850 is used. RF/DC conversion the maximum efficiency is 38% is achieved with 10dBm input power level. A uniform distribution of sensor node with network loads is utilized to control the WSN performance of Base station location as well as distance. For such reason Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is utilized.
