英文摘要：

The rapid advances in processor and radio technology enable the development of wireless sensor networks.However,the severe energy constraints of the sensors present major challenges for long-term applications.In order to achieve sustainability,environmental energy harvesting has been demonstrated as a promising approach.In this work,we divide the energy utilization system to three parts with different functions： energy harvesting,energy consuming and energy storage.Then we formulate the sustainability problem as an energy flow control problem.
