INTRODUCTION :

I NTRODUCTION -IT CONSIST OF AUTONOMOUS SENSORS -MONITOR ENVIRONMENT CONDITION SUCH AS SOUND,VIBRATION,PRESSURE,MOTION OR POLLUTANTS -PASS DATA THROUGH NETWORK TO MAIN LOCATION -THEY ARE BIDIRECTIONAL -CONTROL ACTIVITY OF SENSORS

ARCHITECTURE DESIGN:

ARCHITECTURE DESIGN 1. SENSING UNIT a. sensors b. ADC 2. PROCESSINNG UNIT a. microcontroller b. memory 3. POWER UNIT 4. TRANSCEIVER UNIT

What are wireless sensor networks (WSNs)?:

What are wireless sensor networks (WSNs)? Networks of typically small, battery-powered, wireless devices. On-board processing, Communication, and Sensing capabilities. 1- 5

WSN node components:

WSN node components Low-power processor. Limited processing. Memory. Limited storage. Radio. Low-power. Low data rate. Limited range. Sensors. Scalar sensors: temperature, light, etc. Cameras, microphones. Power. 1- 6 Sensors Processor Radio Storage P O W E R WSN device schematics

CHARECTERISTICS OF WSN:

CHARECTERISTICS OF WSN 1. ENERGY EFFICIENCY 2.DISTRIBUTED SENSING 3. WIRELESS NETWORKS 4. MULTI HOP- BASE STATION 5.NODE TYPE a. HOMOGENOUS GROUP b. HETEROGENOUS GROUP 6.APPLICATION ORIENTED a. military, environmental, heath care

SENSOR NODES:

SENSOR NODES A sensor node, also known as a mote. Mote is a node in a wireless sensor network that is capable of performing some processing, gathering sensory information and communicating with other connected nodes in a network. Sensor able to detect vibration, chemicals, radiation, biological agents, voice ,still images etc…

SMARTDUST:

SMARTDUST WIRELESS COMMUNICATION DEVICE MEASURE LIGHT AND TEMPERATURE CREATE FLEXIBILITY LOW POWER NETWORKS

USES OF SMART DUST:

USES OF SMART DUST Monitor humidity and temperature in refrigerators Detecting onset of diseases such as cancer Airplane sensors- wings of plane Optical switching devices Energy saving Sensors embedded into building supports that affect stress sensing
