INTRODUCTION
Security System for Power Plant which uses
wireless Sensor Network we are using WHM-l Wireless Module This security system that we designed to detect trespasses and feedback message sends to administrator through LAN
WIRELESS SENSOR NETWORK ARCHITECTURE
WSN is a wireless network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations.
SPECIFICATION
Frequency Digital input Analog input Transmission speed Size Modulation Transmission current Receive current Voltage 318.82MHz to 320.32MHz 6 input 8 input 9600bps 66mmx60mm FSK 18.8mA 23.7mA DC3.3V
Programmed WHM-1 Module
Wireless sensor node
Nodes use to communicate each other
Wireless sensor node with multi hop
Nodes use to detect the trepasses
Wireless centre node
Nodes use to sends the information through LAN
Packet tranfer
Flowing of packet transfer will taking place in two ways 1. Between sensor node and sensor node with multi hop 2.Between sensor node and center node
ADVANTAGES Multi access channel Low-power wireless module Multi-hop routing Small antenna is sufficient FSK modulation DISADVANTAGES Area of coverage will be less It’s requires more number of sensor nodes Cost will be high Renewing information every time
CONCLUSION
We proposed a multi-hop transmission for
this system in sensor network. The success probability of communications data could taking place. Nearly distance is close to 70 percent of success that can be obtained. Low power consumption sensor is adopting necessary in future work Wireless sensor network communication success rate is necessary to improve.
