2 M2M/IoT/SDC Systems Need to enable low-cost solutions for large scale deployment M2M/IoT/SDC will achieve global scale if we truly support plug-and-play interoperability for connected devices and IoT systems taking full advantage of new Web technologies and the Cloud Service Capabilities Standards are critical for plug and play Learning and reusing from the industrial automation sector

4 M2M/IoT/SDC Definitions Machine-to-Machine communications A form of data communication which involves one or more entities that do not necessarily need human interaction. The entities include devices (e.g. sensor modules or identity tags), network/application interface devices (e.g. data collectors or tag readers), network elements, and functional entities (e.g. application server or controllers). Smart Device Communications is a form of data communication which involves one or more entities similar to M2M Communication or MTC; however, SDC do consider the applications with limited human interaction. The entities include devices (e.g. sensor modules, identity tags, smartphones and electronic book readers), network/application interface devices (e.g. data collectors or tag readers), network elements, and functional entities (e.g. application server, controllers, and Web servers). * Source: TIA TR50.1 SDC Standard Definitions, Dec 2011

5 M2M/IoT/SDC Definitions Sensor Module A sensor is a device that detects and measures a physical, chemical, and bio-chemical quantity and converts it into a signal which can be read by an observer or by an instrument. A sensor module typically includes circuitry to convert the measures into digital readings that can be ported into a computer or a digital communication device. Smart Device Any sensing or actuating element coupled with an embedded, accessible intelligence controller * Source: TIA TR50.1 SDC Standard Definitions, Dec 2011

6 Gateway M2M/IoT/SDC Definitions In a communications network, a gateway is a network node equipped for interfacing with another network that uses different protocols. A gateway may contain devices such as protocol translators, impedance matching devices, rate converters, fault isolators, or signal translators as necessary to provide system interoperability. It also requires the establishment of mutually acceptable administrative procedures between both networks. A protocol translation/mapping gateway interconnects networks with different network protocol technologies by performing the required protocol conversions. Routers exemplify special cases of gateways. Gateways, also called protocol converters, can operate at any layer of the OSI model. The job of a gateway is much more complex than that of a router or switch. Typically, a gateway must convert one protocol stack into another. * Source: TIA TR50.1 SDC Standard Definitions, Dec 2011

7 Remote Sensing M2M/IoT/SDC Definitions Remote sensing is the small or large-scale acquisition of information of an object or phenomenon, by the use of either recording or real-time sensing device(s) that are wireless, or not in physical or intimate contact with the object (such as by way of aircraft, spacecraft, satellite, buoy, or ship). In practice, remote sensing is the stand-off collection through the use of a variety of devices for gathering information on a given object or area. Middleware Middleware is the software modules connecting application software and operating systems. Typically, it consists of User Interface (UI) and Application Interface (API). * Source: TIA TR50.1 SDC Standard Definitions, Dec 2011

8 Application Servers M2M/IoT/SDC Definitions An application server is a software framework dedicated to the efficient execution of procedures (programs, routines, scripts) for supporting the construction of applications. The term was originally used when discussing early client server systems and servers that ran SQL services[1] and middleware servers to differentiate them from file servers. An application server acts as a set of components accessible to the software developer through an API defined by the platform itself. Normally the term refers to java application servers. When this is the case, the application server behaves like an extended virtual machine for the running applications, handling transparently connections to the database at one side, and connections to the web client at the other. * Source: TIA TR50.1 SDC Standard Definitions, Dec 2011

10 AAA-SD M2M/IoT/SDC Definitions provide authentication, authorization and accounting services to other entities in the network to establish and enforce security policies. The services may include generation of keys, generation and validation of certificates, validation of signatures, etc. (SD -> Smart Devices) Home Application The home application is responsible for the business logic, either directly or via supervision and interaction with node and PoA applications and with PoA devices Node Application The node application acts as an intermediary between the home application and the PoA application and between the home application and the PoA device. Interacts with home application, PoA application and PoA device. May perform functions such as a data aggregation, a load balancing, etc. * Source: TIA TR50 PN _V05 SM2M/Smart Device Communications Reference Architecture, Dec 2011

11 PoA Application M2M/IoT/SDC Definitions PoA application provides resources to node or home applications or to other PoA applications. Interacts with home, node and PoA applications and with PoA devices. May perform functions such as autonomous reporting of values reported by devices, monitoring for values reported by devices that exceed specified limits, trend analysis of values reported by devices, etc. Container Software applications operate within containers. A container is hosted on a physical device, but there may be more than one container per physical device. A container may span multiple physical devices. The container provides services to the applications that operate within it, and enforce security policies * Source: TIA TR50 PN _V05 SM2M/Smart Device Communications Reference Architecture, Dec 2011

19 The Need to Standardize IoT Service Capabilities Common Global Minimum Set Common Protocols Designed to be extensible Promotes Interoperability Enables Plug and Play subsystems Supports differentiation in Features Supports different regional regulatory requirements

20 Some Thoughts OneM2M Partnership Project happening now GISFI participation? Input from GISFI on Service Capabilities should reflect real industrial experience GISFI should add value through knowledge from novel vertical markets GISFI should facilitate plug and play and certification testing of IoT systems and devices in India
