In wireless sensor networks (WSN), the nodes are low powered devices and hence designing a low power WSN is highly important for getting longer lifetime. In this paper, we have discussed several aspects of design and operations of low power WSN. We have reviewed and critically analysed different design issues such as dynamic power management, ultra-low power node design, duty cycle assignment and medium access control.
