Matter originated in December 2019 as the Project Connected Home over IP (or CHIP for short) working group, founded by Amazon, Apple, Google and the Zigbee Alliance, now called the Connectivity Standards Alliance (CSA). [3] [5] Subsequent members include IKEA, Huawei, and Schneider. [8] [9] Version 1.0 of the specification was published on 4 ...
Thread is an IPv6-based, low-power mesh networking technology for Internet of things (IoT) products. [1] The Thread protocol specification is available at no cost; however, this requires agreement and continued adherence to an end-user license agreement (EULA), which states "Membership in Thread Group is necessary to implement, practice, and ship Thread technology and Thread Group specifications."
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]
The basic ULE wireless network uses a “star network topology”; i.e. there is one main device, called “base”, which controls the network; the “base” is wirelessly connected to “nodes”, which usually are devices with dedicated functions, such as sensors, remote controls, actuators, smart meters, etc.
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.
The Connected Home over IP project group was launched and introduced by Amazon, Apple, Google, [212] Comcast and the Zigbee Alliance on December 18, 2019. [213] The project is backed by big companies and by being based on proven Internet design principles and protocols it aims to unify the currently fragmented systems.
6LoWPAN (acronym of "IPv6 over Low-Power Wireless Personal Area Networks") [1] was a working group of the Internet Engineering Task Force (IETF). [2] It was created with the intention of applying the Internet Protocol (IP) even to the smallest devices, [3] enabling low-power devices with limited processing capabilities to participate in the Internet of Things.
