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.
Protocol stack of the OSI model. The protocol stack or network stack is an implementation of a computer networking protocol suite or protocol family.Some of these terms are used interchangeably but strictly speaking, the suite is the definition of the communication protocols, and the stack is the software implementation of them.
OMA Lightweight M2M (LwM2M) is a protocol from the Open Mobile Alliance for machine to machine (M2M) or Internet of things (IoT) device management and service enablement. [1] The LwM2M standard defines the application layer communication protocol between an LwM2M Server and an LwM2M Client which is located in an IoT device.
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."
MQTT (originally an initialism of MQ Telemetry Transport [a]) is a lightweight, publish–subscribe, machine-to-machine network protocol for message queue/message queuing service. It is designed for connections with remote locations that have devices with resource constraints or limited network bandwidth, such as in the Internet of things (IoT).
The IoTivity is an open source framework created to standardize inter-device connections for the IoT. [1] 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.
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.
The presentation layer establishes data formatting and data translation into a format specified by the application layer during the encapsulation of outgoing messages while being passed down the protocol stack, and possibly reversed during the deencapsulation of incoming messages when being passed up the protocol stack. For this very reason ...
