Abstract

The invention aims at providing a transmission power control method and a system, so as to utilize the transmission power control of a terminal device to reduce the electric energy consumption of the terminal device and further prolong the service life of the terminal device. The transmission power control method comprises the following steps: (A) using a plurality of mutually different transmission power to broadcast respective power level messages; and (B) setting the transmission power of the terminal device as the minimum value of the power level messages received by the terminal device.

Description

technical field [0001] The present invention relates to a transmission power control method and system, in particular to a method and system for controlling transmission power of a wireless network terminal device. Background technique [0002] With the advancement of MEMS technology and the development of wireless transmission technology, the application of wireless sensor networks (WirelessSensor Networks) has become more and more popular. The wireless sensor network is a network system composed of one to several wireless data collectors and a large number of sensors (Sensor), and the communication method between components is wireless communication, so sensors can be placed arbitrarily or The wireless data collector is extremely convenient and fast in arrangement. Under the framework of the wireless sensing network, the design of the sensor is aimed at power saving, low price, small size, and sensing environment devices, which can target the things we are interested in i...
