Wireless works
A high-tech solution for a broad range of applications
A wireless work (WSN) is a wireless
network consisting of spatially distributed
autonomous devices using sensors to
cooperatively monitor physical or environmental
conditions.
Nodes consist of: hardware (microprocessor,
memory, battery, MEMS sensor, antenna,
etc.), software, RF protocol, OS

Stage of Development
• Prototypes of motes using this architecture have been
created and low power consumption levels demonstrated
• However, the innovation is architecture, and not a specific
design or product, so feasibility must demonstrated for
specific application-specific embodiments
