What are the constraints of sensor nodes in the sensing layer of the Internet of Things?

In the perception layer of the Internet of Things, sensor nodes have constraints in energy, computing power, communication capacity, storage capacity and so on. According to the public information related to the query, in the sensing layer of the Internet of Things, sensor nodes usually need to run for a long time, so energy is an important constraint. In addition, the computing ability, communication ability and storage ability of sensor nodes have certain constraints, which need to be optimized and balanced according to specific application scenarios. For example, in some low-power application scenarios, sensor nodes usually use low-power processors and communication modules to extend their running time.
