IEEE 1377-2012- IEEE Standard for Utility Industry Metering Communication Protocol Application Layer

IEEE P2413- Standard for an Architectural Framework for the Internet of Things (IoT)

IEEE 802.15.4 is a standard which specifies the physical layer and media access control for low-rate wireless personal area networks (LR-WPANs). It is maintained by the IEEE 802.15 working group. It is the basis for the ZigBee,ISA100.11a, WirelessHART, and MiWi specifications, each of which further extends the standard by developing the upper layers which are not defined in IEEE 802.15.4. Alternatively, it can be used with 6LoWPAN and standard Internet protocols to build a wireless embedded Internet.

Based on the standard ISO/IEC 18092:2004, using inductive coupled devices at a center frequency of13.56 MHz. The data rate is up to 424 kbps and the rangeis with a few meters short compared to the wireless sensornetworks.

A list of IoT software projects like Contiki, Riot OS, etc can be foundhere.

The purpose and goal of oneM2M is to develop technical specifications which address the need for a common M2M Service Layer that can be readily embedded within various hardware and software, and relied upon to connect the myriad of devices in the field with M2M application servers worldwide.

JMS (Java Message Service) – A Java Message Oriented Middleware (MOM) API for sending messages between two or more clients.

CCN directly routes and delivers named pieces of content at the packet level of the network, enabling automatic and application-neutral caching in memory wherever its located in the network. The result? Efficient and effective delivery of content wherever and whenever it is needed. Since the architecture enables these caching effects as an automatic side effect of packet delivery, memory can be used without building expensive application-level caching services.

The communication model aims at defining the main communication paradigms for connecting entities, as defined in the domain model. We provide a reference communication stack, together with insight about the main interactions among the actors in the domain model. We developed a communication stack similar to the ISO OSI 7-layer model for networks, mapping the needed features of the domain model unto communication paradigms. We also describe how communication schemes can be applied to different types of networks in IoT.
