Abstract

The invention discloses a WBAN energy and data transmission time distribution method adopting WPT technology. The method comprises the following steps: an arbitrary m-th wireless sensor node obtains channel fading coefficient through a common pilot channel and sends the channel fading coefficient to a handheld terminal. After receiving the channel fading coefficients of M wireless sensor nodes, the handheld terminal sends them to the base station. After the base station obtains the channel fading coefficients of all M wireless sensor nodes, The time allocated to all N WPT transmission sourcesfor multiplexing energy is (img file= 'DDA00017747861400011. TIF' wi= '67' he= '63' / ) when data is allocated to any m-th wireless sensor node between (imgfile= 'DDA0001774786140000012. TIF' wi= '85' he= '62' / ) base station will feed back (img file= 'DDA00017747861400013. TIF' wi= ' 51 'he=' 64 ' / ) and (img file=' DDA0001774786140000014. TIF 'wi=' 58 'he=' 60 ' / ) to N WPT transmitting sources and handheld terminals via SDCCH channel; Handheld terminals will transmit (img file= 'DDA00017747861400015. TIF' wi= '50' he= '65' / ) and (img file= 'DDA00017747861400016. TIF' wi = '59' he= '63' / ) to M wireless sensor nodes through SDCCH channel. High efficiency energy and data transfer rate allocation can be performed for sensor nodes with different wireless channel transmission conditions.
