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.
A security association is a procedure to identify a node and a hub to each other, to establish a new Master Key (MK) shared between them, or to activate an existing MK pre-shared between them. The security association in the IEEE 802.15.6 standard is based on four key agreement protocols that have security problems. [ 2 ]
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.
The user interface of home automation software is often based on a client-server model, such as a web UI or a smartphone app, or some combination thereof. More advanced applications will allow users to write scripts in a programming language to handle more complex tasks.
Its goal is to facilitate interoperability among smart home devices, mobile apps, and cloud services, employing a specific suite of IP-based networking technologies such as mDNS and IPv6. [26] By adhering to a network design that operates at the Application Layer of the OSI 7 layer model , Matter differs from protocols like Zigbee or Z-Wave and ...
Some smart home hubs support a wider selection of components, while others are more specialized for controlling products within certain product groups or using certain wireless technologies (e.g. Wi-Fi, Bluetooth, Z-Wave, and/or Zigbee). A smart speaker with a virtual assistant can often be used for speech input to a smart home hub.
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]
Z-Wave is a wireless communications protocol used primarily for residential and commercial building automation. It is a mesh network using low-energy radio waves to communicate from device to device, [2] allowing for wireless control of smart home devices, such as smart lights, security systems, thermostats, sensors, smart door locks, and garage door openers.
