Aims
From Glacsweb Wiki
Requirements
- smaller cheaper node (than Iceland one)
- Core sensing
- electrical conductivity
- tilt/pitch/roll
- temperature
- radio tuned to the sediment
- ad-hoc network allowing data hopping
- Sample every 10 minutes, radio coms every hour as a starting point
- adaptive sampling rate (or at least mechanism to change schedules)
- sends data via Overo/ARM to web database system/s
- easy management of data and admin info from the system
Technical aims
- test 433MHz TI SoC - aim for MSP430 core
- Contiki OS
- system data so we can understand performance
- behaviour/mode messages to nodes
- test in soil to find wet/dry range and max hop count issues
- use off the shelf core embedded hardware plus custom sensor board
- data system and management - lots of ways to see/export data, create event triggers etc
- and see system performance, change system configuration/timings etc
- possibly analyses data looking for events
- command and control - network performance etc
- must be deployable in Jan 2011
- local deployment on sea defences is another test application
