Introduction

WISENET is a network of low-power consumption.

wireless sensor network that monitors the environmental conditions such as light, temperature, humidity.

Design GoalsUse of Commercial-Off-The-Shelf (COTS)

software & standard interfaces where applicable

Hypertext Transfer Protocol (HTTP)Structured Query Language (SQL)

Simple, web-based user interface

Battery-powered, wireless sensor nodes: 'motes'

Low-power consumption = Long battery life

Design Methodology

primary SubsystemsData Analysis Data Acquisition

System ComponentsClientServerSensor mote network

System Block Diagram

Sub system-Client The Client component is any computer

with a web browser and Internet access could be a Client.

Sub system-server

Web program

Written in PHP4

Utilizes Charting Software: Chart Director v3.0

Passes Parameters via HTTP GET

Retrieves Data for Specific Mote or All Motes

Wise DBWritten in C++Utilizes open-source APIs • Application Programming Interfaces (API)Relays information from mote network to

databaseSends commands to mote network

Sub system-sensor mote networkThe component responsible for collecting

and transmitting raw environmental data to the Server.

There is also the potential for the motes to receive commands from the Server.

TinyOSReal-time operating system for

microcontrollersKey Features:

• Developed for sensing applications• Emphasis on low-power: Idle & sleep

modes• Highly modular architectureCurrently developed for Atmega

microcontrollers

Applications Lab / Office Monitoring. Security Applications. Extreme Weather Surveillance. Potential Biomedical Applications.

ConclusionWireless sensor networks are getting

smaller and faster, increasing their potential applications in commercial, industrial, and residential environments.
