5A and 3i
To achieve such 5A (anything, anywhere, anytime, anyway,
anyhow) and 3I (instrumented, interconnected, and
intelligent) capabilities, some common, horizontal, general-
purpose technologies, standards, and platforms, especially
middleware platforms based on common data
representations just like the three-tiered application server
middleware, HTML language, and HTTP protocol in the
Internet/web arena, have to be established to support
various vertical applications cost effectively,

What is M2M?
M2M uses devices (such as an in-vehicle gadget) to
capture events (such as an engine disorder), via a network
(mostly cellular wireless networks, sometimes wired or
hybrid) connection to a central server (software program),
that translates the captured events into meaningful
information (alert failure to be fixed).

Strategy Analytics identifies five key barriers to
scaling the global M2M market
1. Lack of a low-cost local access media that can
be implemented on a global basis
2. The fragmented nature of both the technology
vendors and the solutions they provide

3. Lack of any single killer application that can
consolidate the market and drive demand forward
4. The increased costs associated with
development and integration because of the
complex nature of M2M solutions
5. Management’s inability to express the benefits
of M2M in anything other than cost savings,
rather than exploiting and encouraging the service
enablement capacity of mobile M2M

1) Service enablement is a middleware layer that facilitates the creation of
applications
2) A significant percentage of the functionality of the middleware comes from
the charging, mediation, service management, and network management
solutions that are being deployed in next-generation networks.
3) value chain of M2M business, which can be separated into two parts: the
first relating to devices and the second to application development and
service delivery
4) The broad intersection between these two parts represents the means by
which devices are procured and integrated into M2M solutions and
services

M2M:The Internet of Devices
1) The M2M device market share of chipset vendors including TI,
Infineon, ST-Ericsson, Qualcomm, and others, and module
vendors including Enfora, Infone, Kyocera, Murata, Mobicom,
Novatel, Panasonic, Semco, Siemens, Sierra Cellular, Simcom,
Telit, Wavecom, and others
2) As MNOs become more directly involved with M2M application
service providers (ASPs), some MNOs such as Sprint, AT&T,
Verizon Wireless, China Mobile, China Telecom, China Unicom,
Orange, Rogers Communications, Telenor, Telefonica, NTT
DOCOMO, and others are actively deploying M2M-based services

1) Many are deploying key network elements, specifically mobile packet
gateway, specifically for their M2M operations, separate from their
general mobile data infrastructure. Key benefits of doing this are that it
simplifies internal business operations and optimizes use of the network
2) A mobile virtual network operator is a communications service provider
that does not use its own infrastructure to provide connectivity but
leases out infrastructure from one or more cellular network carriers to
offer a more competitive mobile connectivity plan
3) MVNOs active in the M2M market are also increasingly deploying
mobile packet gateways and similar equipment to interconnect with
their MNO partners’ radio infrastructure
Examples of MVNO:Sprint, T-Mobile, and U.S. Cellular

RFID: The Internet of Objects
1) The term Internet of Things was first used by
Kevin Ashton, co-founder and executive
director of the Auto-ID Center
2) An RFID tag is a simplified, low-cost, disposable
contactless smartcard.
3) RFID tags include a chip that stores a static
number (ID) and attributes of the tagged
object and an antenna that enables the chip to
transmit the store number to a reader

1) When the tag comes within the range of the
appropriate RF reader, the tag is powered by
the reader’s RF field and transmits its ID and
attributes to the reader
2) An RFID system involves hardware known as
readers and tags, as well as RFID software or
RFID middleware
3) RFID tags can be active, passive, or semipassive

1) Passive RFID does not use a battery, while an
active has an on-board battery that always
broadcasts its signal.
2) A semipassive RFID has a small battery on
board that is activated when in the presence of
a RFID reader.

SAMPLE APPLICATIONS
Product Tracking – RFID tags are increasingly used as a cost-effective way to
track inventory and as a substitute for barcodes.
Toll Road Payments – Highway toll payment systems
Passports incorporate RFID tags into passports to store information (such as a
photograph) about the passport holder and to track visitors entering and
exiting the country.
Identification – RFID chips can be implanted into animals and people to track
their movements, provide access to secure locations
Libraries – Libraries use RFID tags in books and other materials to track
circulation and inventory, store product information (such as titles and
authors), and to provide security from theft
Shipping – Large shipments of materials, such as retail goods, often utilize RFID
tags to identify location, contents, and movement of goods. Wal-mart

 A transducer is an electronic device that
converts energy from one form to another
 Common examples include microphones,
loudspeakers, thermometers, and
antenna
WSN: The Internet of Transducers

1) Definition:A Wireless sensor network can be defined as
a network of devices that can communicate the
information gathered from a monitored field through
wireless links.
2) A Sensor is a device that responds and detects some
type of input from both the physical or environmental
conditions, such as pressure, heat, light, etc

1) A sink, on the other hand, collects data from sensors
2) The sink may communicate with the end-user via direct
connections, the Internet, satellite, or any type of
wireless links
3) Sensor node: sense target events, gather sensor
readings, manipulate information, send them to gateway
via radio link ◾ Base station/sink: communicate with
sensor nodes and user/operator ◾ Operator/user: task
manager, send query

1) Types of Sensor
a. Thermal
b. Electromagnetic
c. Mechanical
d. chemical
e. Optical radiation

1) In practice, special cases of WSNs are encountered
such as wireless multimedia sensor networks (WMSNs),
underwater wireless sensor networks (UWSNs),
wireless underground sensor networks (WUSNs),
wireless body sensor networks (WBSNs) and wireless
sensor-actor networks (WSANs)

1) Multimedia Wireless Sensor Networks
The emergence of integrated complementary metal–oxide–
semiconductor camera sensors and integrated
microphones, with low power consumption and even low
cost, has allowed the development of a subfield in WSN
research that is called wireless multimedia sensor networks
(WMSNs)

1) Multimedia WSNs

1) WMSNs are characterized by their capability of
collecting multimedia, mainly video and audio streams,
as well as still images, from the environment
2) One of the potential applications is real-time multimedia
surveillance, both in private areas and in critical
infrastructures that are susceptible to terrorist attacks,
such as airports or public sport centers

1) Compared with traditional surveillance systems, visual WSNs allow extending area
monitoring by scaling the number of cameras
2) Typically, these kinds of networks are deployed in a preplanned manner, to
guarantee full coverage and to make easier the information processing
3) In the case of supervised video monitoring, information has to be transmitted
from the visual sensors to a central controller, where it can be analyzed from
either a human operator or an automatic system
4) The challenges with the multimedia WSN include high energy consumption, high
bandwidth requirements, data processing, and compressing techniques

2.Under Water WSNs
1) More than 70% of the earth is occupied with water
2) These networks consist of several sensor nodes and
vehicles deployed underwater
3) Autonomous underwater vehicles are used for gathering
data from these sensor nodes
4) A challenge of underwater communication is a long
propagation delay, bandwidth and sensor failures.

Underwater, WSNs are equipped with a limited battery that
cannot be recharged or replaced
The issue of energy conservation for underwater WSNs
involves the development of underwater communication
and networking techniques.

3.Under Ground WSNs
1) Wireless underground sensor networks (WUSNs), which are
characterized by the fact that the sensors are buried
underground, located in caves or mines or embedded within
dense soil or rock have been proposed to monitor conditions in
these environments.

1) The WSNs networks consist of several sensor nodes that are
hidden in the ground to monitor underground conditions.
2) To relay information from the sensor nodes to the base station,
additional sink nodes are located above the ground
3) The underground wireless sensor networks deployed into the
ground are difficult to recharge
4) In addition to this, the underground environment makes wireless
communication a challenge due to the high level of attenuation and
signal loss

4.wireless body sensor networks (WBSNs)
1. A Wireless Body Sensor Network (WBSN) defines an autonomous system
which is used to monitor the daily life activities of a person.
2. It consists of intelligent sensor nodes which do not hamper the daily life
activities and are useful in detecting chronic diseases like heart attack, asthma
etc

SCADA: The Internet of Controllers
1. Building automation systems (BAS) would become fully integrated with
communication and human interface practices and standards widely employed
for information technology systems.
2. SCADA (supervisory, control and data acquisition) systems, as the core
technology of the controls–IT convergence, will evolve and take the center
stage.
3. it is an industrial computer-based control system employed to gather and
analyze the real-time data to keep track, monitor and control industrial
equipments in different types of industries

SCADA was generally referring to industrial control systems (ICSs): computer
systems that monitor and control industrial, infrastructure, or facility-based processes
as follows
1. Industrial processes include those of manufacturing, production, power generation,
fabrication, and refining, and may run in continuous, batch, repetitive, or discrete modes
2. Infrastructure processes may be public or private and include water treatment and
distribution, wastewater collection and treatment, oil and gas pipelines, electrical power
transmission and distribution, wind farms, civil defense siren systems, and large
transportation systems
3. Facility processes occur in both public and private facilities, including buildings, airports,
ships, and space stations. They monitor and control HVAC, access, and energy
consumption using PLCs (programmable logic controllers) and DCSs (distributed control
systems) via the OPC (OLE for process control) middleware

An existing SCADA system usually consists of the following
subsystems
1. Human–machine interface (HMI)
2. Remote terminal units (RTUs)
3. PLCs
4. DCSs
5. M2M (telemetry), WSN, smart systems

1. A SCADA system could be a layer between the top-layer business systems
such as ERP, WMS, SCM, CRM, EAM (enterprise asset management), PIMS
(plant information management system), EMI (enterprise manufacturing
intelligence), LIMS (laboratory information management system), and
other applications and the lower layer DCS, PLC, RTU, MES
(manufacturing execution system), SIS (supervisory information system in
plant level), and others
2. A traditional SCADA system is a client/server system
3. New technological developments have turned C/S SCADA systems into
middleware-backed, web-based, three-tiered open systems with SOA
capabilities

1. Consider the application of SCADA in power systems for operation
and control
2. SCADA in power system can be defined as the power distribution
application which is typically based on the software package.
3. The electrical distribution system consists of several substations;
these substations will have multiple numbers of controllers, sensors
and operator-interface points

1. In general, for controlling and monitoring a substation in real time
(PLCs) Programmable Logic Controllers, Circuit breakers and Power
monitors are used.
2. Data is transmitted from the PLCs and other devices to a computer-
based-SCADA node located at each substation. One or more
computers are located at different centralized control and monitoring
points
