Design Goals Use of Commercial-Off-The-Shelf (COTS) software &

standard interfaces where applicable Apache web-server (HTTP) MySQL database PHP web programming language

Simple, web-based user interface

Battery-powered, wireless sensor nodes: 'motes' Low-power consumption = Long battery life Motes create self-organizing ('ad-hoc') networks for

robust communications

TinyOS

Real-time operating system for microcontrollers Open-source project at UC Berkeley Key Features:

Developed for sensing applications Emphasis on low-power: Idle & sleep modes Highly modular architecture Efficient utilization of resources

Currently developed for Atmega microcontrollers

Project Success Wisenet is partially operational

2 Motes w/ prototype sensor boards TinyOS modified for CC1010 Server running WiseDB + web interface Sensor boards are not currently powered by

batteries. Problems with DC-DC converter

Unable to test multi-hop routing due to lack of motes

Future Projects / Extensions Expand network to develop & test

multi-hop routing Develop a single-board mote

Create a expandable, plug-in sensor interface Research alternative energy sources

Solar cell, rechargeable batteries Continue development of TinyOS

Improve tools Optimize performance / reduce power usage

Improve web interface Data analysis
