    As we know, the energy needed for sensors should be electrical. So the rst step before start to work is to convert environmental energy to electrical one. Inside the node there are dierent components for sensing the area, collecting data and processing the data. So the main dierent part of this kind of nodes, in compare of WSN nodes, is the power part. Once the stored energy reach to a certain amount, the power supply for micro controller and transceiver will start to work. They will continue to work until they have energy, as soon as the energy nish, they stops and energy storage device start to work to save energy again. The other fact should be consider about EH-WSN node is that the available energy can change in dierent nodes. So every node has its own harvesting rate.
