WIRELESS SENSOR NETWORK5
What it is ? A group of tiny, typically battery-
powered devices and wireless infrastructure
What are the components ? One or more sensors, embedded
processors and low-power radios, and is normally battery operated
What it does ? Monitor and record conditions of
different environment Sends data to back end system for
analysis

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
