Aims

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
