Abstract

Harvesting energy from the environment is essential for many applications to slow down the deterioration of energy in sensor networks. Energy from the environment is an inexhaustible supply which, if properly managed and harvested from the sources, can allow the system to last for a longer period. Many simulators simulate whole sensor networks where the nodes rely on energy harvesting for their source of power. It is important to be able to assume and simulate a node that can harvest energy from different sources of ambient energy. It is also essential to be able to keep track of the energy levels of the node and adjust node activities based on its energy status. This study aims to develop a prototype for a single node simulator that will show the effects of harvesting from different sources of energy. The results of this study can later be extended for more complicated simulations.

주변 환경으로부터 에너지를 수확하는 것은 많은 응용 분야에서 센서네트워크의 에너지를 고갈시키는 상황을 완화시키는 데 필수적이다. 주변환경으로부터 얻을 수 있는 에너지는 적절하게 관리되고 수확된다면 시스템을 더욱 오랫동안 지속할 수 있게 한다. 이제까지 많은 시뮬레이터 들은 전원을 에너지 수확에 의존하는 센서네트워크를 시뮬레이션 하였다. 노드들이 에너지를 다양한 주변 에너지원으로부터 수확한다고 가정하고 시뮬레이션을 할 수 있다는 것은 매우 중요한 일이다. 또한, 에너지의 잔량을 지속적으로 추적하고 이에 따라 노드의 활동을 조정하는 것도 필수적이다. 본 연구의 목적은 각기 다른 에너지원에 따른 에너지 수확의 효과를 보여주는 단일 노드 시뮬레이터를 제안하는 것이다. 본 연구의 결과는 향후 더욱 정교한 시뮬레이션을 위하여 확장이 가능 하다.
