Abstract

The invention is suitable for the wireless communication technology field and discloses an energy efficiency transmission method of a wireless body area network. The method comprises the following steps of establishing an unit bit energy consumption model of a wireless body area network communication system and acquiring a value range of a transmission rate, calculating a threshold distance according to the unit bit energy consumption model and a minimum value of the transmission rate; if a current transmission distance is less than the threshold distance, using an optimization algorithm to acquire an optimum transmission rate according to the unit bit energy consumption model and the value range of the transmission rate, and carrying out data transmission as the optimum transmission rate. The invention also discloses an energy efficiency transmission apparatus of the wireless body area network. By using the method and the apparatus of the invention, energy consumption of the wireless body area network communication system with a short transmission distance can be reduced and the service life of a cell is effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to an energy-efficient transmission method and device of a wireless body area network. Background technique [0002] Wireless Body Area Network (WBAN, Wireless Body Area Network) is a communication network centered on the human body and composed of network elements related to the human body. In recent years, with the rapid development of wireless technology, wireless body area network has become more and more widely used due to its portability and other advantages. The main popular application directions are telemedicine services, entertainment and military. [0003] By placing different network nodes around the human body or on the surface of the skin, these network nodes form a local area network around the human body and transmit data wirelessly. However, since the energy of the network nodes is mainly powered by the battery, and the energy of the batt...
