Remote sensor systems looking to Zigbee Alliance By Bryon Gloden, Murat Senel, and Waseem Sheik

Slide 2

What is a sensor? Little, independent PCs, containing: sensors that permit information obtaining "PC\'\' that permits information preparing radio that permits information correspondence Battery worked Ability to self-arrange into specially appointed systems Programmable, running TinyOS Example: PicoRadio, 2 AA bateries, 40 Kbps RFM TR 100, Detachable sensor sheets: temperature, photograph, mouthpiece, Applications incorporate common and military

What is ZigBee? ZigBee Technology that a ddresses the market requirements for financially savvy remote systems administration arrangements in view of IEEE 802.15.4 standard IEEE 802.15.4: Wireless MAC and PHY details for low-rate remote individual territory systems (LR-WPANs) Ultra-low many-sided quality, ultra-minimal effort, ultra-low power utilization, and low information rate (20-250 kb/s) remote network among reasonable gadgets Lower control, bring down cost than different WPANs (e.g. Bluetooth) ZigBee Alliance Non-benefit industry consortium characterizing a worldwide determination for dependable, financially savvy, low power remote applications in view of the IEEE 802.15.4 standard. Six promoters (Honeywell, Invensys, Mitsubishi, Motorola, Philips, and Samsung) and more than 80 members

Article Summary Planned accreditation program to guarantee sensors meet particulars, interoperability and sensibility. RTM final quarter of 2004. Minimal effort of sensors will probably make them a more great alternative over other WPAN advances.
