Power Beacon Placement for Maximizing Guaranteed Coverage in Bistatic Backscatter Networks

The bistatic backscatter architecture, with its extended range, enables flexible deployment opportunities for devices. In this paper, we study the placement of power beacons (PBs) in networks to maximize guaranteed coverage distance (GCD), defined as from reader within which devices are able satisfy a given quality-of-service constraint. This work departs conventional energy source problems by considering performance additional link on top transfer link. We adopt and optimize symmetric PB scheme GCD. optimal under is obtained using either analytically tractable expressions or an efficient algorithm. Numerical results provide useful insights into impacts various system parameters resulting GCD, plus advantages adopted over other benchmark schemes.
