IoTivity
The IoTivity is an open source framework created to standardize inter-device connections for the IoT. Any individual or company can contribute to the project, and this may influence OCF standards indirectly. However, being a member of the OCF can benefit from patent cross-licensing protection. The IoTivity architectural goal is to create a new standard by which billions of wired and wireless devices will connect to each other and to the Internet. History In October 2016 they announced AllJoyn merger into Iotivity. The group hoped that devices running either AllJoyn or Iotivity would be interoperable and backward compatible. On October 10, 2016, the AllSeen Alliance merged with the Open Connectivity Foundation (OCF) under the OCF name and bylaws. OCF then sponsored both the IoTivity and AllJoyn open source projects. The merged groups announced that they will collaborate on future OCF specifications, as well as the IoTivity and AllJoyn open source projects, and current devices ...

AllJoyn
AllJoyn is an open source software framework that allows devices to communicate with other devices around them. A simple example would be a motion sensor letting a light bulb know no one is in the room it is lighting, so it can shut itself off. Originally the AllSeen Alliance promoted the project, from 2013 until 2016 when the alliance merged with the Open Connectivity Foundation (OCF). In 2018 the source code became hosted by GitHub. History The AllJoyn technology was promoted by Qualcomm in 2011. In December 2013, Qualcomm signed over the source code and trademark to the Linux Foundation with the creation of the AllSeen Alliance. The alliance promoted interoperability for the Internet of things, and a number of consumer brands signed on including LG, Sharp Corporation, Haier, Panasonic, Sony, Electrolux, Sears and Arçelik. Other members included Silicon Image, Cisco, TP-Link, Canary, Changhong, Two Bulls, Affinegy, doubleTwist, Fon, Harman, HTC, LIFX, Liteon, Muzzl ...

Network Layer
In the seven-layer OSI model of computer networking, the network layer is layer 3. The network layer is responsible for packet forwarding including routing through intermediate routers. Functions The network layer provides the means of transferring variable-length network packets from a source to a destination host via one or more networks. Within the service layering semantics of the OSI network architecture, the network layer responds to service requests from the transport layer and issues service requests to the data link layer. Functions of the network layer include: ; Connectionless communication : For example, IP is connectionless, in that a data packet can travel from a sender to a recipient without the recipient having to send an acknowledgement. Connection-oriented protocols exist at other, higher layers of the OSI model. ; Host addressing :Every host in the network must have a unique address that determines where it is. This address is normally assigned from a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Message
A message is a discrete unit of communication intended by the source for consumption by some recipient or group of recipients. A message may be delivered by various means, including courier, telegraphy, carrier pigeon and electronic bus. A message can be the content of a broadcast. An interactive exchange of messages forms a conversation. One example of a message is a press release, which may vary from a brief report or statement released by a public agency to commercial publicity material. History Roles in human communication In communication between humans, messages can be verbal or nonverbal: * A verbal message is an exchange of information using words. Examples include face-to-face communication, telephone calls, voicemails, email etc. * A nonverbal message is communicated through actions or behaviors rather than words, such as conscious or unconscious body language. In computer science There are two main senses of the word "message" in computing: messages ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Service Discovery
Service discovery is the process of automatically detecting devices and services on a computer network. This reduces the need for manual configuration by users and administrators. A service discovery protocol (SDP) is a network protocol that helps accomplish service discovery. Service discovery aims to reduce the configuration efforts required by users and administrators. Service discovery requires a common language to allow software agents to make use of one another's services without the need for continuous user intervention. Protocols There are many service discovery protocols, including: * Bluetooth Service Discovery Protocol (SDP) * DNS Service Discovery (DNS-SD), a component of zero-configuration networking * DNS, as used for example in Kubernetes * Dynamic Host Configuration Protocol (DHCP) * Internet Storage Name Service (iSNS) * Jini for Java objects. * Lightweight Service Discovery (LSD), for mobile ad hoc networks * Link Layer Discovery Protocol (LLDP) standar ...

Zigbee
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. Hence, Zigbee is a low-power, low data rate, and close proximity (i.e., personal area) wireless ad hoc network. The technology defined by the Zigbee specification is intended to be simpler and less expensive than other wireless personal area networks (WPANs), such as Bluetooth or more general wireless networking such as Wi-Fi. Applications include wireless light switches, home energy monitors, traffic management systems, and other consumer and industrial equipment that requires short-range low-rate wireless data transfer. Its low power consumption limits transmission distances to 10–100 meters line-of-sight, depending on power ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ANT+
Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22,000 species have been classified. They are easily identified by their geniculate (elbowed) antennae and the distinctive node-like structure that forms their slender waists. Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies that may occupy large territories and consist of millions of individuals. Larger colonies consist of various castes of sterile, wingless females, most of which are workers (ergates), as well as soldiers (dinergates) and other specialised groups. Nearly all ant colonies also have some fertile males called "drones" and one or more fertile females called "queens" ( gynes). The colonies are described as superorganisms because the ants ap ...

Z-Wave
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, allowing for wireless control of smart home devices, such as smart lights, security systems, thermostats, sensors, smart door locks, and garage door openers. The Z-Wave brand and technology are owned by Silicon Labs. Over 300 companies involved in this technology are gathered within the Z-Wave Alliance. Like other protocols and systems aimed at the residential, commercial, MDU and building markets, a Z-Wave system can be controlled from a smart phone, tablet, or computer, and locally through a smart speaker, wireless keyfob, or wall-mounted panel with a Z-Wave gateway or central control device serving as both the hub or controller. Z-Wave provides the application layer interoperability between home control systems of different manufacturers that are a part of its alliance. There is ...

Thread (network Protocol)
Thread is an IPv6-based, low-power mesh networking technology for Internet of things (IoT) products. Thread is reliable, secure and delivers fast response times, extended coverage and years of battery life to elevate smart home and building experiences. 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 that "Membership in Thread Group is necessary to implement, practice, and ship Thread technology and Thread Group specifications." Thread uses 6LoWPAN, which, in turn, uses the IEEE 802.15.4 wireless protocol with mesh communication (on the 2.4 GHz spectrum), as does Zigbee and other systems. However, Thread is IP-addressable, with cloud access and AES encryption. A BSD-licensed open-source implementation of Thread, calledOpenThread, is available from and managed by Google. In 2019, the Connected Home over IP project (later renamed "Matter"), led by Zigbee Al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bluetooth Low Energy
Bluetooth Low Energy (Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) aimed at novel applications in the healthcare, fitness, beacons, security, and home entertainment industries. It is independent of classic Bluetooth and has no compatibility, but Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) and LE can coexist. The original specification was developed by Nokia in 2006 under the name Wibree, which was integrated into Bluetooth 4.0 in December 2009 as Bluetooth Low Energy. Compared to Classic Bluetooth, Bluetooth Low Energy is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range. Mobile operating systems including iOS, Android, Windows Phone and BlackBerry, as well as macOS, Linux, Windows 8, Windows 10 and Windows 11, natively support Bluetooth Low Energy. Compa ...

Ethernet
Ethernet () is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3. Ethernet has since been refined to support higher bit rates, a greater number of nodes, and longer link distances, but retains much backward compatibility. Over time, Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET. The original 10BASE5 Ethernet uses coaxial cable as a shared medium, while the newer Ethernet variants use twisted pair and fiber optic links in conjunction with switches. Over the course of its history, Ethernet data transfer rates have been increased from the original to the latest , with rates up to under development. The Ethernet standards include several wiring and signaling variants of the OSI physical layer. Systems communicating over Ethern ...
