Analysis of the different aspects of the Internet of things in the cloud computing technology

The Internet of things and cloud computing are comparable in many ways, for example, cloud computing has three tiers of SPI (SaaS, PaaS, IaaS), and the Internet of Things has three tiers of DCM (i.e., perceptual, transport, application). NIST (American Institute of Standards and Technology) divides the cloud computing deployment into a common cloud, private cloud, community cloud and mixed cloud, the existence mode of the Internet of Things is divided into intranet, private network and extranet; as well as cloud computing, the deployment pattern of the Internet of Things is divided into public-IoT, proprietary networking ( Private IoT), community Networking (Community IoT) and mixture networking (Hybrid IoT).

Based on the idea of NIST (National Institute of Standards and Technology), this paper puts forward a definition of the internet of things and a normative proposal of architecture, hoping to unify the industry's thinking, so that we have a common language and reference in the dialogue on the Internet, so as to play a role.

The definition of Internet of things

The idea of the Internet of Things is to refer to the ubiquitous (ubiquitous) terminal equipment (Devices) and facilities (facilities), including devices with "intrinsic intelligence" such as sensors, mobile terminals, industrial systems, building control systems, Home smart facilities, video surveillance systems, and "external enabling" items such as RFID-labeled assets (Assets), personal or vehicle-carrying wireless terminals, and other "intelligent objects or animals", long distances and/or or short distance communication network to achieve interconnection (machine-to-machine), the application of large integration (grand integration). Internet of things can be based on the cloud of SaaS and other operating modes, in the intranet (intranet), private network (EXTRANET/VPN) or Internet (Internet) environment, the use of appropriate information security mechanisms to provide security (privacy protection) and even personalized real-time online monitoring, Positioning traceability, alarm linkage, dispatch command, plan management, Process Control, remote maintenance, online upgrades, statistical reports, decision support, Leadership Desktop (Dashboard) and other management and service functions, to achieve "everything" (things) "high efficiency, energy saving, safety, environmental protection" of "control, control, camp" Integration Services.

Four types of deployment

Private IoT: Providing services within a single organization may be implemented and maintained by an agency or a third party to which it is entrusted, primarily within an internal (on Premise) intranet (intranet) or outside the institution (off premise).

Public IoT: The Internet (Internet) provides services to the public or to large groups of users, generally by the Agency (or its delegated third party, a few cases).

Community Networking (Community IoT): Provides services to an associated "community" or group of institutions (such as the Public Security Bureau, the Transport Bureau, the Environmental Protection Bureau, the Urban Management Authority, etc.), which is affiliated with a city government. It is possible to coordinate the operation of two or more institutions, mainly in intranet and special network (EXTRANET/VPN).

Mixture Networking (Hybrid IoT): A combination of the above two or more things, but there are unified operational entities in the background.

Ten basic functions

The most basic feature of the Internet of Things is to provide "ubiquitous connectivity and online services" (ubiquitous connectivity), with ten basic functions.

Online monitoring: This is the most basic function of the Internet of things, the network of things generally focused on monitoring, supplemented by control.

Location traceability: Generally based on GPS (or other satellite positioning, such as Beidou) and wireless communication technology, or only rely on wireless communication technology positioning, such as based on mobile base station positioning, RTLS and so on.

Alarm linkage: Mainly provides event alerting and prompting, and sometimes provides linkage functions based on workflow or rule engine (rules "s Engine).

Command scheduling: Command, Dispatch and dispatch functions based on time scheduling and event response rules.

Contingency management: The disposal of events arising from a predetermined set of regulations or regulations.

Security privacy: Due to the importance of Internet ownership and privacy protection, the IoT system must provide the corresponding security mechanism.

Remote maintenance: This is the internet of things technology can provide or upgrade services, mainly applicable to Enterprise products After-sale networking Services.

Online Upgrade: This is to ensure that the Internet system itself can be normal operation of the means, but also the enterprise product After-sale automatic service means one.

Leadership Desktop: Mainly refers to the dashboard or bi personalized portal, through the multi-layer filtering of real-time information, can be for the responsible person to achieve the overall "at a glance."

Statistical decision-making: Refers to the network information based on data mining and statistical analysis, to provide decision support and statistical reporting functions.

Four technical forms

Rfid:rfid is an "enabling" technology that can turn a conventional "instrumented" (IBM "3I" description) into a connection to the Internet of things. Based on the related epc/uid and pnl/ons technology, it can also be used as the "Unified identification" reference technology for the whole IoT system.

Sensor network: WSN, OSN, BSN and other technologies are the end of the network of things, mainly to solve the "last 100 meters" connection problem, the end of the sensor network generally refers to smaller than the machine-to-machine end of the micro-sensing system, such as Mote.

Machine-to-machine: Focus on mobile terminals interconnection and integrated management, mainly telco (communication operators) of the Internet of things business, there are MVNO (Mobile virtual network operators) and MMO (Machine-to-machine mobile operators) and other business models.

Two fusion: refers to the industrial automation and control system Information upgrade, industrial control, building control and other industries are the main driving force for the integration, but also can include smart grid and other industry applications.
