energyharvesting

代码说明：

  Energy Harvesting wireless sensor network(EH-WSN) is a kind of WSN that uses rechargeable power supply instead of using traditional battery. In traditional WSN, the energy sources is limited. When the power source of node nish, it can not continue to work unless it is recharged again. So the eort was to design energy-ecient network protocols to maximize the lifetime of WSN by minimizing energy usage.if we can have access to unlimited power, we can have innite lifetime in network. This unlimited power can be provide by environment such as light, vibration and heat. Then stores the harvested energy in a storage device. When the device uses energy harvested instead of battery, the residual energy is no more an useful quantity to preserve. In EH-WSN, if the rate of harvesting power is lesser than the power used by the node, the sensor node should go to sleep to charge up.
