The Internet of Things (IoT)
The Internet of Things (IoT) is a network of physical objects, devices, vehicles, etc. which are embedded w/ electronics, sensors, software & network connectivity.
Enables objects to collect & exchange data w/ minimal human intervention. Objects can be sensed & controlled remotely across existing network infrastructures. Creates opportunities for integration between computer-based systems & physical world. Results in improved accuracy, efficiency & economic benefit.

The Internet of Things (IoT)
Kevin Ashton (British entrepreneur) coined the term IoT in 1999. Referring to a global network of radio-frequency identification (RFID) connected objects. First smart device network began w/ a modified Coke machine at Carnegie Mellon
University in 1982, used the Internet to report inventory & product temperature readings. “Things” refers to various devices; heart monitoring implants, biochip
transponders, DNA analysis devices, auto sensors, etc. IoT products can be classified into five main categories.
Those categories are Smart Wearable, Smart Home, Smart City, Smart Environment, and Smart Enterprise.

The Internet of Things (IoT)
Gartner anticipates 6.4 billion connected “things” will be used globally in 2016. Up 30% from 2015; expected to reach 20.8 billion by 2020. In 2016, 5.5 million new “things” will become connected daily. Services are dominated by professional categories where businesses enter
into contracts w/ external providers to design/install/operate systems. Connectivity services & consumer services will become faster growing.
The Internet of Things (IoT)
The ability to network embedded devices w/ limited CPU, memory & power resources means IoT has applications in nearly every industry.
Healthcare
Devices inside of or attached to
the human body such as monitors
used to track human fitness
levels & wellness; fitbits, heart monitors,
emergency notification
systems, etc.
Retail
Devices that monitor how consumers engage in everyday
commerce activities; self-
checkout, inventory
optimization devices,
scanners, etc.
Environmental
Sensors used to monitor & assist in environmental protection; water
quality, soil conditions,
atmospheric conditions,
earthquakes, wildlife
movement & habits, etc.
Infrastructure
Devices used to manage urban &
rural infrastructures
such as bridges, train tracks, wind
farms; used to predict events or
changes in structural
conditions & schedule
maintenance, etc.
Factories
Devices that monitor standard
production environments w/
repetitive routines such as
hospitals & farms; monitor
operating efficiencies, optimizing
equipment use & inventory, etc.
Transportation
Systems & sensors inside
moving vehicles such as
airplanes, cars, trains, ships;
condition-based maintenance,
pre-sales analytics, usage-
based design, fleet
management, smart traffic control, etc.

Device-to-Device Communication Two or more devices which directly connect & communicate w/ one another. Not dependent on intermediary application servers. Communicate via numerous different networks. Follow certain communication protocol to achieve their functions. Exemplified in applications such as home automation systems.
Light bulbs/light switches/thermostats/door locks, etc. Interoperability issues appear due to built-in security/trust mechanisms & device-specific data models.

Device-to-Cloud Communication
Device connects directly to Internet cloud service, such as an application service provider, to exchange data & control message traffic (e.g. SAP HANA Cloud1).
Utilizes existing communication mechanisms such as Ethernet or Wi-Fi to establish connection w/ IP network & devices.
Allows for remote access to devices & supports software updates. Adds value by extending capabilities beyond native device features.
Employed by devices such as Nest Labs Learning Thermostat 442 & Samsung Smart TV3. Interoperability issues appear when integrating devices by different manufacturers. Proprietary data protocols may tie devices to specific cloud services (vendor lock-in).

Device-to-Gateway Communication Known as Device-to-Application-Layer Gateway Model (ALG). Device connects through an ALG service as a conduit to access a cloud service.
Application software operating on a local gateway device. Intermediary between cloud service & device; provides security/data or protocol translation. No native ability to connect to cloud service directly.
Device-to-Gateway model’s primary feature is the ability to overcome proprietary device restrictions in connecting devices.
Gateway between individual IoT devices & cloud service; bridge interoperability gap themselves. Adds complexity & costs to overall system (more generic Internet protocol models in the works).

Back-end Data Sharing
Communication architecture that allows users to analyze & export smart object data from a cloud service in combination w/ data from other sources.
Grants access to uploaded 3rd party sensor data. Extension of single device-to-cloud communication model. Allows users to relocate/share data when switching between IoT services.
Federated cloud services or cloud application programmer interfaces (APIs) required for interoperability of smart devices hosted via cloud.
Only as effective as the underlying IoT system; cannot overcome closed system designs. Light Sensor

IoT Privacy
Privacy rights & expectations are critical to ensuring Internet trust. Every single day, new legal & regulatory challenges are emerging. Everyone has different personal privacy expectations & ability to trust the Internet. Unknown 3rd party information/data sharing & analyzing exhibited (e.g. social media).
Traditional “notice & consent” online privacy model; devices frequently have no user interface to configure privacy preferences.
Creates a gulf between privacy preferences & data-collecting behavior.
Copyright © Blackvard Management Consulting – All rights reserved www.blackvard.com
Users are hesitant to buy devices w/ vendor lock-in or inflexibility in integration w/ other devices.
Limits new product creation based on software architecture. Huge attraction to cloud services such as SAP HANA Cloud; which provide
interoperability & valuable information & services based on collected data. Moving across various service providers is challenging. Data in proprietary format is often useless to users. Open standard data format required to move data from one provider to the next.
IoT Standards

IoT Security
Is IoT developing too rapidly, without critical security consideration & appropriate regulatory changes being made?
Cyber attacks are likely to become physical as well as virtual in the near future. Internet-connected appliances spying & computer-controlled devices controlled remotely.
Parallel sensor fusions can undermine social cohesion. Consequences to electronic commerce, technical innovation, free speech, online activities, etc. Existing tools, methods & strategies may need new consideration. Lack of upgradability, internal function visibility, & security notifications can lead to cyber attacks.

Real World Business Use Case
Shipment trucks continuously sending data to SAP HANA Cloud Platform. In order to provide the required information, each truck has a mobile device (e.g. mobile
phone w/ an installed application), satellite positioning (e.g. GPS), that send information to the warehouse; the information can be used as needed (e.g. for pickers, daily shift planning, tracking optimization, real-time analysis, etc.).

Real World Business Use Case Benefits
Shipment trucks are able to continuously send data in order to have real-time insights about their fleet.
Evaluate positions & sensor data in the SAP HANA Cloud platform dashboard. Allows companies to generate forecasts for ideal flow within their supply chain. Guarantees ideal conditions for transported goods by monitoring environment parameters. Lower environmental impact, CO2, and fuel costs by optimizing fleet & routes.
