RF-Based Charger Placement for Duty Cycle Guarantee in Battery-Free Sensor Networks
[article]
2015
arXiv
pre-print
Preserved Fulltext
Based on a new wireless recharge model, we formulate the charger placement problem for node's duty cycle guarantee as a constrained optimization problem. ...
The simulation results show that the proposed particle swarm optimization (PSO)-based divide-and-conquer approach can effectively reduce the number of chargers compared with the greedy approach. ...
The charger placements are shown in Fig. 2(a) and Fig. 2(b) with α fixed at 0.5. ...
