Description: 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-e cient network protocols to maximize the lifetime
of WSN by minimizing energy usage.if we can have access to unlimited power, we can have in nite
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.
