Abstract:
Topic:ADVANCEMENT OF ZIGBEE TECHNOLOGY
OBJECTIVE: In todays modern world technological
advancements are improving and developing at a very fast
pace.In this scenario the world is also facing a bigger crisis and
that is power crisis.The world today is in intense need of
technologies that can save power and yet enhance the
efficiency.At this juncture I present an illustration on
ADVANCEMENT OF ZIGBEE TECHNOLOGY,which presents
tremendous oppurtunities in fornt of us to design almost infinite
life batteries.
INTRODUCTION:
ZigBee is an established set of specifications for wireless
personal area networking (WPAN), i.e.digital radio connections
between computers and related devices. WPAN Low Rate or
ZigBee provides specifications for devices that have low data
rates, consume very low power and are thus characterized by
long battery life. ZigBee makes possible completely networked
homes where all devices are able to communicate and be
controlled by a single unit
ZIGBEE TRAFFIC :
• Data is periodic. The application dictates the rate, and the
sensor activates, checks for data and deactivates.
• Data is intermittent. The application, or other stimulus,
determines the rate, as in the case of say smoke detectors.
• Data is repetitive, and the rate is fixed a priori. Depending on
allotted time slots, called GTS (guaranteed time slot),
devices operate for fixed durations.
CONCLUSION:
It is likely that ZigBee will increasingly play an
important role in the future of computer and communication
technology. In terms of protocol stack size, ZigBee's 32 KB is
about one-third of the stack size necessary in other wireless
technologies (for limited capability end devicesZigBee technology
is designed to best suit these applications, for the reason that it
enables reduced costs of development and very fast market
adoption.
