CA belongs to a class of protocols called multiple access methods. In CSMA, a station wishing to transmit. (1) listen to the channel for a predetermined amount of time. (2) If the channel is sensed "idle" then transmit. If the channel is sensed as "busy“. the station has to defer its transmission.
Introduction to Zigbee Technology. Page 2. 1. Introduction. ZigBee is the most popular industry wireless mesh networking standard for connecting sensors, instrumentation and control systems. ZigBee, a specification for communication in a wireless personal area network. (WPAN), has been called the "Internet of things.

It is a technical standard for communication protocols using small, low power, digital radios for personal area networks (PAN),. IEEE International Standard 802.15.4, typically operating at 2.4 GHz. It's target market is low power applications with infrequent data transmission needs. What is Zigbee?
6. How Is ZigBee Related to IEEE 802.15.4? ? ZigBee takes full advantage of a physical radio and MAC layers specified by IEEE 802.15.4 (lower layers). ? ZigBee adds logical network, security and application software (higher layers). ? ZigBee continues to work closely with the IEEE to ensure an integrated and complete
Section 5 introduces the broadcast procedures in ZigBee. Some application examples of WSN are introduced in Section. 6. Finally, we conclude this chapter in Section 7. 2 IEEE 802.15.4 Basics. IEEE 802.15.4 specifies the physical layer and data link layer protocols for low-rate wireless personal area networks (LR-WPAN),

This page on zigbee tutorial covers zigbee network elements coordinator and end device,zigbee protocol stack,zigbee frame structure,zigbee physical layer,MAC frames etc.
Examine the basics of the IEEE 802.15.4 standard. • Examine the basics of the ZigBee software stack. What makes ZigBee different? What is ZigBee? The term ZigBee is used to describe a standardized wireless protocol for personal area networking, or “WPAN." The protocol is the work of and property of the ZigBee.
