Node for Energy Saving of wireless sensors (1)

Wireless sensor networks are increasingly used. As a result, wireless sensor networks are becoming more and more popular with green and economical technologies. Please refer to the following for more information about the basis and node issues related to energy saving of wireless sensor networks.

Automatically configured wireless sensor networks are of great value in civil and military fields and can be used to collect, process, and publish complex environmental data in a wide range. Nodes in wireless sensor networks are generally powered by batteries, and the power available is very limited. for wireless sensor networks with thousands of nodes, it is very difficult or even impossible to replace the battery. However, wireless sensor networks require several months or even years to survive. Therefore, without affecting functions, saving the battery energy of wireless sensor networks as much as possible has become the core issue in the software and hardware design of wireless sensor networks, and is also the focus of domestic and foreign research institutions.

Node composition and Energy Consumption Analysis

The standard Wireless Sensor node Structure 1 is shown. A node consists of four parts:

1) A computing subsystem composed of a microprocessor or a microcontroller;

2) Short-range wireless transceiver circuit used for wireless communication, that is, the communication subsystem;

3) a sensor subsystem that associates nodes with the physical world and consists of a group of sensors and incentive devices;

4) Energy Supply subsystem, including battery and AC-DC converter.
