Power management in Wireless Sensor Network
Deepti Goyal, Sonal · International Conference on Computing for Sustainable Global Development · 2016
Wireless Sensor Network has greatly evolved the energy efficient utilization. In WSN sensor nodes, have limited energy budget so this paper mainly focus on harvesting of energy and power saving. The selection of cooperation nodes must be a long time usable batteries because batteries are not easily rechargeable and available which is not reliable. The selection of such nodes to reduce error estimation and power conserving. In this paper focus on algorithms, approaches and techniques which deals how to increase efficiency of battery. For efficient energy stable power and long term system adopts a Maximum power point tracking (MPPT) circuitry. In power saving techniques employs power control and power management techniques. Power control includes two factors distance and link factor which affect the power transmission. Power management schema use energy harvesting schemes on different nodes by sleep/awake method. Energy efficient algorithms increase efficiency of power and life time of battery.
