RIOT-OS Logger Roadmap

The UiO WSN system will now be broken into different components:

• Sensor kit made of sensors and a microcontroller running Arduino firmware
• Main brain to run power management, sampling, data management, networking
• Gateway
• Test applications (e.g. GPS network pinger)

Software features and requirements

Logger program

• regular loop alarm trigger

• deep sleep when not active

• I2C, SDI12 capability, Serial UART (maxbotix)

• Logging actions (different level of logging. Use humna readable timestamp)

• data management:

  • Local copy of data on microSD
  • queue management
  • network acknoledgement

• power management:

  • different level of usage,
    • anostic power level (based on battery level only)
    • Arctic mode based on latitude and timestamp with winter/summer mode

• watchdog

• network (802.15.4) in either Peer-to-peer or star topology

• parallelized task? or multithreading

• RTC clock sync with network/GPS

• All config in a main config file. Some config can be overwritten interactively:

  • node name
  • time setting
  • sensor sampling loop

• WAN: 4G, Iridium

• LAN: radio

• i2c IO multiplexer (sensor control)

• Power consumption calculator (based on accessories consumption and loop)

• Store in the mote the program version (commit number)

• uBloc GPS family (RIOT GPS parser)

• plan for scenario:

  • mote loose connectiont to LAN or WAN

• config file sent to DB

• Long term: Send new config via network

Custom Digital sensor kits

• code written in Arduino C#. Use SDI12 protocol to communicate to main brain.
• Each sensorkit is a suite of sensors. have command to sample single sensors or the entire suite.
• event based counter (wind propeler sensor) (maybe hardware solution)

Gateway program

Listen to nodes. send ack.
4G/ethernet

Network range test program

Design a very simple program, sampling GPS location every 2s and push position through network (with RSSI recordings).
