The kernel uses this callback to verify that when it allocates a new block, the program claims only the block that was allocated in addition to those it already controlled. Networking The kernel implements a programmable packet filter, which executes programs in a bytecode language designed for easy security-checking by the kernel.
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.
The kernel is the name given to the program that does most of the housekeeping tasks for the operating system. The boot loader hands control over to the kernel, which initializes the various devices to a known state and makes the computer ready for general operations. [10]
RIOT's kernel is mostly inherited from FireKernel, [2] which was originally developed for sensor networks. In 2015, one of the co-developers, Matthias Wählisch was awarded the Young Scientist Award of the Forum for Excellent Young Scientists for the contributions of his team to the open source operating system RIOT.

It provided a standardized, general-purpose horizontal architecture for IoT platform operators and service providers to deploy IoT solutions. Release 2 was issued in August 2016. It added an interworking framework enabling each service provider to support more types of devices on their IoT platform.
Like menuconfig in Linux, a user interface (UI) based configuration tool integrated with CodeBench provides the user with graphically selectable components to customize the kernel at build time. The Nucleus configuration system allows for user customization to integrate new tool-chains, architecture support and build properties.
Contiki is designed to run on types of hardware devices that are severely constrained in memory, power, processing power, and communication bandwidth.A typical Contiki system has memory on the order of kilobytes, a power budget on the order of milliwatts, processing speed measured in megaHertz, and communication bandwidth on the order of hundreds of kilobits/second.
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.
