Overview of low-power strategies for wireless sensor nodes

The energy supply of wireless sensor network nodes is generally borne by batteries, whose energy is limited and not easy to replace, so low power design research is of great value. In this paper, started with the structure design of low-power sensor system, from the local node to the whole network, from the hardware composition to the software implementation, the design scheme and the power consumption characteristics of low-power system based on sensor network nodes is summarized. On this basis, the low-power strategy of wireless sensor network nodes is proposed.
