WISENETWireless Sensor NetworkPresented By: M.Bharani S.Sindhu

INTRODUCTIONWISENET is a network of low-power wireless sensor devices (“motes”)

designed to record and report environmental data.

(MICA mote from Crossbow Technology)

• System Description:• There are two primary subsystems• Data analysis• Data acquisition comprised of three major

componentsClient Server Sensor Mote

TinyOS

TinyOS is a small micro-threading operating system that abstracts core application development from specific hardware details.The design methodology is to 'wire' different components to each other – higher level components call 'tasks' in lower level components, and lower levels signal 'events' to higher levels.tinyOS is completely non blocking which has single stack.

TinyOS

• Sleep Mode – Power Conservation• Query Mode – Data Acquisition• Re-Programming Mode – Future

Option

Modes of Operation

– Environmental Conditions• -20 – 80º C• 0 – 100% Relative Humidity (RH)

– Sensor Accuracy• Light Sensor: ±10% Lumens• Humidity: ±3% RH• Temperature: ±3º C

– Power Usage• 3.3V Operating Voltage• Goal: 6 Month Battery Life

Specifications

–Hardware• Selected most of the components• Preliminary designs

– Software: TinyOS • Analysis of TinyOS 1.0.0 source code (nesC)• Began port to CC1010 hardware•Working on simple Blink application

Project Progress

Software design shelf products

• Apache• PHP• MySQL• Chart Director Software custom components: . Web program . WiseDB . Port of tinyOS

– Lab / Office Monitoring– Habitat Monitoring– Security Applications– Extreme Weather Surveillance– Potential Biomedical Applications– Military Reconnaissance

Project Applications

CONCLUSION• Wisenet represents commercial

applications.• Strength Of Wisenet-Open source

development community.• Wisenet draws on the strength of

tinyOS design methadology.
