  1. A mote is a small wireless hardware platform, similar to a computer. • It has its own processor, flash memory, sram, and serial flash memory.

  2. Many motes together make a Wireless Sensor Network (WSN) • In WSNs motes form a network by communicating, listening and transmitting information to and from each other and a base station mote. • A mote can be programmed to sense light, temperature, magnetism, acceleration, and sound with an attached sensor board.

  3. There are many different type of motes • The motes used were Mica2’s. • Mica2 motes are the fifth generation of motes made by University of California, Berkley and Intel, released in 2003. • They have a 7mhz processor, 128kb programmable flash memory, 4kb Static RAM for storing data and variables.

  4. There are two ways to program motes • The more common way is to attach the mote to a programming board which is connected via ethernet cable or serial port. • The second way is Over The Air Programming(OTAP). To OTAP a mote, OTAP must be enabled when programming an attached mote with a seperate program.

  5. Deploy a WSN using Mica2 motes. • Motes in the WSN must be programmable over the air(OTAP). Meaning a user can select a mote to program and program it while it is deployed. • Program motes to send less often. • Program motes to send less information.

  6. Mote-View • MoteConfig • Programmers Notepad • Lantronix Device Installer • Xserve • PostgreSQL

  7. Graphical User Interface for WSNs • Provides visualization and analysis of sensor data • Provides database management

  8. MoteConfig – is a tool to program the motes. It provides the ability to program motes over the air and motes that are attached to the programming board. • Programmers Notepad – a robust IDE for many languages, however NesC for TinyOS is what is used to program motes.

  9. Lantronix Device Installer – is a program to manually assign IP addresses to the MIB600 ethernet programming boards. • Xserve – is a data logging utility that posts to a PostgreSQL database. • PostgreSQL – An SQL database. Can be stored locally or over a LAN or online.

  10. Long learning curve. • Hardware is very unreliable. • Software is very unreliable. • Documentation provided is bad.

  11. NesC proficiency is needed to understand what the code does • Learn the ins-and-outs of all aforementioned tools. • Overcoming software and hardware errors with no troubleshooting documentation.

  12. The hardware is not consistent - The programming boards and motes act differently between different hardware setups. - Power supplies for motes are inconsistent at best

  13. Mote-View would have random software errors • MoteConfig would cause memory leak. • Xsniffer – never worked. • Device Installer was a whole version behind the newest available for download • OTAP would not work until Mote-View was updated to 1.4 revision B.

  14. Tutorials were not in-depth enough, and lacked detail • User manuals were more tutorials • No troubleshooting in user manuals • No established community information provided.

  15. The “magical” router, a spare D-link router we had, worked. It worked regardless of setup or system. • OTAPing never worked when two ore more programming boards are connected to the same network • MoteConfig does not clear memory.

  16. Deploy a WSN using Mica2 motes. • Motes in the WSN must be programmable over the air(OTAP). • Program motes to send less often. • Program motes to send less information. • All achieved.

  17. A quick demo • Then Q&A
