RF Energy Transmission17

Received power is inversely proportional to

Remote nodes from the Robot will get less energy compared to the closer ones

Circular disk model for wireless power propagation

Landmark Selection18

The number of landmarks should be minimized Integer Linear Programming (ILP) model

CPLEX to determine the landmark locations by solving the ILP formulation

The number of landmarks in each cluster depends on the demand intensity Di

Clustering and Path Selection19

landmarks are grouped based on their proximity to the docking stations of the MICROs

each MICRO is assigned one cluster of landmarks Hamiltonian cycle to achieve optimal path selection

Minimum power availability of theMICRO

Harvester energy is limited The total supply of the harvester should be greater than

or equal to the energy requirement of the sensors
