Abstract

The invention discloses a transmitting power adjusting method, a control terminal and a sensor node, used for solving the technical problem that energy consumption of the sensor node in the prior art is too high. The method comprises the following steps: the control terminal receives at least one data packet sent by the sensor node; the at least one data packet is a part or all data packets of a first data frame; whether the at least one data packet can form the complete first data frame or not is judged, so that a judgement result is obtained; the count value of a counter corresponding to the sensor node is adjusted according to the judgement result; the fact that the count value satisfies a threshold value condition is determined, so that a control instruction is generated, wherein the control instruction is used for adjusting the transmitting power of the sensor node; and the control instruction is sent to the sensor node.

Description

technical field [0001] The invention relates to the fields of wireless communication and medical care, in particular to a method for adjusting transmission power, a control terminal and a sensor node. Background technique [0002] Wireless Body Area Network (WBAN) is a communication network centered on the human body and composed of sensor nodes all over the body or inside the human body. A sensor node is a device that includes biosensors that can measure physiological parameters of the human body and can communicate with the control terminal. Wherein, the sensor nodes may specifically include wearable or implantable biosensors for measuring body temperature, blood pressure, heart rate, blood oxygen concentration or other physiological parameters. After each sensor node measures the physiological parameters of the human body, it can send the physiological parameters of the human body to the control terminal for reference by the user. The control terminal may be a portable ...
