On-Demand MAC Protocol for Energy Harvesting - Wireless Sensor Networks
Energy Harvesting (EH) provides a promising solution to one of the biggest problems faced by Wireless Sensor Net- works (WSN), namely the energy supply. By harvesting en- ergy from the surrounding environment, the sensors can have an innite lifetime without any needs for battery recharge or replacement. Battery-powered WSNs are typically designed to maximize the energy conservation in order to postpone as much as possible the inevitable battery depletion. Instead, EH-WSNs are being designed on a dierent principle. The focus is on maximizing the network performance while op- erating at a state that is energetically sustainable. In this paper, we present ODMAC, an on demand MAC protocol for EH-WSNs which is able to support individual duty cycles for nodes with dierent energy proles. Hence, each node is able to increase its energy consumption, thus its perfor- mance, to the level that the energy consumed is at the same level to the energy harvested. The protocol is implemented and evaluated using the OPNET simulator .
