Tiny OS / Wireless Sensor Network

• TinyOS is a small open source OS for wireless
  embedded sensor networks
• Using TinyOS and MICA2 433 MHz motes for
  application
• Development done on Windows using Cygwin unix
  environment
• MICA2 motes used for radio xmission / reception
  and sensor boards used for temp and light sensing

• Plan for application is as follows
• - Sense temperature and light in one node
• - Send this data through one or more other nodes
  using a routing protocol
• - When it data gets to node with PC
  communication, send the data to the PC
• - If a node doesnt have any peers it can route
  to (link broken) sound the buzzer after a timeout
  period of trying to re-establish routing.
