Recent years have witnessed wireless harness of in-equipment sensor networks (ISNs). Existing wire harness imposes hardware restriction on maintenance, design, and weight of ISNs. FD-SWIPT (full-duplex simultaneous wireless information and power transfer) is expected to enable wireless harness with bandwidth limitation. This paper proposes FD-SWIPT-mAP (FD-SWIPT with multiple access points) which medium access method for FD-SWIPT in ISNs. FD-SWIPT-mAP allocates power and data transmission with centralized control and battery level estimation. Simulation results show that the data achievement rate of FD-SWIPT-mAP using 10 access points is approximately 14 times higher than using one access point.
