Abstract

The invention provides a node of a wireless sensor network based on reinforcing type hybrid power control. The node comprises a sensing unit, a processing unit, a communication unit and a power supply, wherein the power supply is connected with the sensing unit, the processing unit and the communication unit; the sensing unit is interconnected with the processing unit; and the processing unit is interconnected with the processing unit. The processing unit adopts an ARM7TDMI-S LPC213X microcontroller; and the communication unit adopts a CC2420 wireless receiving-transmitting chip. With the adoption of the node of the wireless sensor network based on receiving type hybrid power control, the energy consumption of the sensor network is obviously reduced; and the service life of the wireless sensor network is prolonged. The power consumption brought by idle listening is effectively reduced; the shortcoming of single power control technology is overcome; and the effect of effectively adjusting sending power and transmitting power can also be achieved.

Description

technical field [0001] The present invention relates to wireless sensor network technology, more specifically, to a node of a wireless sensor network based on enhanced hybrid power control. Background technique [0002] The 21st century is an era of rapid development of IT technology, among which wireless sensor network technology is undoubtedly one of the most influential technologies, which has attracted great attention internationally. Wireless sensor network technology is a multi-disciplinary technology, which combines embedded computing technology, distributed information processing technology, sensor technology and communication technology, etc., and has become a highly integrated research direction. [0003] A wireless sensor network is a multi-hop network composed of a large number of sensor nodes deployed in the target area for mutual cooperation, perception, and self-organization. The sensor nodes monitor the information of the deployed target area through mutual ...
