Zigbee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios, such as for home automation, medical device data collection, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection.
IEEE 802.15.4 protocol stack. Devices are designed to interact with each other over a conceptually simple wireless network.The definition of the network layers is based on the OSI model; although only the lower layers are defined in the standard, interaction with upper layers is intended, possibly using an IEEE 802.2 logical link control sublayer accessing the MAC through a convergence sublayer.
While most of the modules in this list are Zigbee, Thread, ISA100.11a, or WirelessHART modules, some don't contain enough flash memory to implement a Zigbee stack and instead run plain 802.15.4 protocol, sometimes with a lighter wireless protocol on top.
The relationship between IEEE 802.15.4 and Zigbee [8] is similar to that between IEEE 802.11 and the Wi-Fi Alliance. The requirements for membership in the Alliance cause problems for free-software developers working with Zigbee because the annual fee conflicts with the GNU General Public Licence. [9]
Nodes typically connect in a star or mesh topology. While most individual nodes in a WSAN are expected to have limited range (Bluetooth, Zigbee, 6LoWPAN, etc.), particular nodes may be capable of more expansive communications (Wi-Fi, Cellular networks, etc.) and any individual WSAN can span a wide geographical range. An example of a WSAN would ...
Ad hoc On-Demand Distance Vector (AODV) Routing is a routing protocol for mobile ad hoc networks (MANETs) and other wireless ad hoc networks.It was jointly developed by Charles Perkins (Sun Microsystems) and Elizabeth Royer (now Elizabeth Belding) (University of California, Santa Barbara) and was first published in the ACM 2nd IEEE Workshop on Mobile Computing Systems and Applications in ...
