Abstract: Infinite body area network system is used to collect human physiological signals. The network uses signal nodes to monitor and judge the health status of human body, and the signal is transmitted through wireless radio frequency network. In order to keep the network running normally, it is necessary to use appropriate communication protocols. A non-standard communication protocol structure based on Nordic nRF24L0 1 chip star topology is proposed. The research goal is to demonstrate the feasibility of the protocol structure based on star topology and provide a solution for the future wireless body area network system.

Keywords:-wireless body area network, nonstandard protocol, star topology
