COMMUNICATION COVERAGE IN WIRELESS PASSIVE SENSOR NETWORK
[attachment=25480]
DESIGN APPROACH
The most challenging design problem of WSN :low-power sensor nodes
Is recharging is an option………?
No…due to limited capacity of batteries, majority of nodes are inoperable.
Solution is……WPSN, power is externally supplied to sensor node via external RF source.
conclusion& futurework
The required number of RF Sources for interference-free communication is obtained in terms of RF communication frequency, RF output power.
The analysis developed here can be used towards determination of design of hybrid model WPSN as well as for RFID networks.
