Problems solved by technology

However, this method will cause a waste of resources, because not every terminal node initiates the connection establishment process in each resource allocation, and not every Connection Request message sent by a terminal node has a maximum length
[0017] It can be seen that in the current wireless body area network connection establishment method, since the central node allocates time resources according to the maximum length and minimum transmission rate of the Connection Request message each time, there is a problem of resource waste

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] The core idea of ​​the present invention is: the central node first allocates resources according to the minimum length of the Connection Request message, and then redistributes a larger amount of resources when it detects that a terminal node is about to establish a connection. Requirements, and can avoid the waste of system resources when the terminal node does not need to send the Connection Request message.

Abstract

This application discloses a method for establishing a connection of a wireless body area network. The central node first allocates resources according to the minimum length of the Connection Request message, and then re-allocates a larger amount of resources when it detects that a terminal node is about to establish a connection. . Adoption of the present invention can not only guarantee to meet the requirements of terminal nodes, but also avoid waste of system resources.

Description

technical field [0001] The invention relates to a wireless body area network communication technology, in particular to a connection establishment method of a wireless body area network. Background technique [0002] With the intensification of my country's urbanization process and population aging, senile diseases and chronic diseases are becoming more and more common. In addition to bringing heavy economic burdens to patients and society, they also seriously affect the quality of life of patients and family happiness. The emergence of Wireless Body Area Network (WBAN) provides a simple and low-cost means of short-distance communication for home health monitoring of geriatric and chronic diseases. Based on WBAN technology, by arranging corresponding sensing devices on the human body surface or in the body, it automatically collects vital sign parameters such as human ECG, EEG, EMG, body temperature, blood pressure, blood sugar, blood oxygen, etc., to support real-time, conv...
