ABSTRACT
The Real-Time Multimedia Systems Laboratory in Carnegie Mellon University has developed a complete wireless sensor networking platform called FireFly comprising of FireFly sensor nodes (SNs), a real-time multitasking operating system (OS) called nano-RK and a time-divisionmultiplexed-access protocol stack. The platform design has been directly driven by the following goals:
1. Low cost: Each node must be relatively inexpensive to enable costeffective acquisition and deployment.
