Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an energy efficiency optimization method oriented to a wireless body area network. Background technique [0002] WBAN nodes in Wireless Body Area Network (WBAN) are portable, and some special nodes even need to be implanted inside the human body, so WBAN nodes need to have the characteristics of small size, light weight, limited energy, and not Easy to perform frequent battery changes. Therefore, the energy consumption of nodes has always been one of the core issues of research. [0003] The research results show that most of the energy of the wireless sensor network nodes is consumed in the wireless communication module [2], so the focus of optimizing WBAN energy consumption is to reduce the energy consumption of the communication module. At present, the main measures taken for WBAN energy consumption include the design of high-energy-efficiency MAC layer protocol, data c...
