Abstract.The article discusses the technical and practical features of the ZigBee wireless
data transmission protocol. It has been talked in details about the device network built on
this standard, its application area, advantages and disadvantages. For greater clarity,
some comparative characteristics with other popular protocols, such as WiFi and Bluetooth
were given. In addition, the article considers the following elements based on this protocol
with their real market value.
Keywords: protocol, networks, ZigBee, wireless, routing, smart home.
Introduction
Today, wireless technology is growing faster. For this reason, the developers were
faced with the question of not only increasing the compactness of such devices, but also
their autonomy and ease of connection. The use of existing data transmission wireless
protocols such as WiFi, GSM or Bluetooth has been proven to be unsuitable for use
in situations that do not require high data transfer speeds running for long periods of
time. This led to the creation of the fourth target group of the IEEE 802.15 standard on
which the ZEBE protocol was developed.
ZigBee protocol options
ZigBee is a high-level protocol that was ratified by the ZigBee Alliance in 2004 and
is based on the IEEE 802.15.4 wireless data standard. There are currently different
versions of the protocol, the name of which corresponds to the name of the year in
which it was created.
The main feature of devices that use ZigBeeni is low power consumption. The
network transmits most of such data using a router, and the end devices connected to
them allow you to spend a lot of time in sleep mode, saving energy. Thus, a device
running on the ZigBee protocol can run on a single AA battery or even AAA class for
two years.
Communication in the ZigBee network is carried out by transmitting data packets
between devices connected to the network, and the following devices are used:
The coordinator starts the network and manages its processes: installs and stores the
security keys of the device, sets the security policy of its network and connects to other
networks. There can be only one coordinator in each ZigBee network.
A router is a device that dynamically transmits packets of data over a network. It can
be connected to other routers or a network coordinator and to other routers or children's
devices. Routers are stationary and can be serviced.Live broadcast on devices designed
for 32 children at the same time, including stationary devices.
A terminating device is a system element that operates from an autonomous power
source and performs a specified function using sensors or actuators. The latter device
connects to a router or coordinator, which can send and receive data packets only
through a router or coordinator. It can't exchange data directly with other latest devices,
so it spends a lot of time in "sleep" mode to save battery power.
Unlike WiFi and Bluetooth, the ZigBee network has a network topology. This allows
routers to be connected to each other to increase system reliability. In the event of a
router crash, data packets are automatically routed through other available routers,
