    How can ensure the data transmission

  • Smart City Data Transmission challenges

    How could we ensure data transmission in large, complex, heterogeneous and mul1-stakeholders systems in

    - Real 'me - Reliable way - Cyber security - Low cost - Energy saving

  • Sensor (A)

    Smart sensor : Internet of Things (IoT) - Unique iden1fier - Geo-localized - Processor (Analysis, control) - Storage capacity - Ability to communicate

  • Sensor (A)

    Smart sensor : Internet of Things (IoT)

    Data transmission

  • In smart City, Internet of things allows to: - Real 1me monitoring of physical parameters (comfort, safety, op1mal management, health ...)

    - Real 1me control of devices, and equipment - Share informa1on between things - Interact with users - Take decisions and ac1ons based on embedded and shared intelligence.

  • Data specifica2on Size Frequency ? Real 1me ? Sensibility (importance) Latencey

    Latency designates the 1me necessary for a packet of data to get from one point to another

  • Wired or wireless infrastructure ?

    Wired infrastructure: Availability Bidirec1onal (transmission and Control) Increased Security regarding wireless technology Large data

  • Reduc2on of the energy consump2on ? - Strategy for data transmission - Frequency, - Embedded intelligence - Data varia1on

  • Reliability: The ability of a system to consistently perform according to its specifica1ons without degrada1on or failure.

    Data transmission security ?

  • Cyber security Technologies, processes and prac1ces designed to protect networks, computers, programs, devices and data from aXack, damage or unauthorized access.

    Data transmission security

  • What to do in case of absence of data transmission? Analysis of the origin:

    Sensors fault Communica1on fault Cyber aXack

    Data transmission security

  • How to check the data transmission? Exchange specific informa2on at specific intervals.

    Data transmission in the electrical Grid

  • HOME AREA NETWORKS (HAN) Neighborhood Area network (NAN) Wide Area Network (WAN)

  • Wireless technologies ZigBee, Wi-Fi, RFID, Bluetooth 6LoWPAN

    HOME AREA NETWORKS (HAN)

    Wired technologies RS485, PLC I2C, SPI

  • The most used protocol in HANs. Operates in the license-free frequency for short range Bidirec1onal Conforms to IEEE 802.15.4. Low data rate, long life baXery

    ZigBee Technology

  • Advantages of using ZigBee in HANs Highly secured connec1on (128-bit AES encryp1on) Low power consump1on; baXeries for longer life1me (100-1000 days)

    Could be used in large network Short latency (15ms to 30ms)

  • Disadvantages of ZigBee ZigBee network requires addi1onal devices

    which increases cost. Appliances running ZigBee are incompa1ble

    with other network protocols such as Wi-Fi. Low data transmission rates Lacks Internet Protocol support

  • Wi-Fi Technology Bidirec1onal radio frequency (RF) Conforms to IEEE 802.11. U1lized for high-rate, informa1on-related devices such as computers, TV, digital camera, data download

  • Advantages of Wi-Fi Highly secured connec1on (128-bit AES encryp1on) does not require a special gateway because it

    inherits the Internet protocol Short latency (less than 3ms)

  • Disadvantages of Wi-Fi in HANs Consumes high power compared to ZigBee (The

    baXery life1me extends from 0.5-5 days) Sensi1ve to electromagne1c radia1on emiXed from

    household appliances, which affects the speed of transmission

    Low latency

  • Wireless communica1ons technology simple, secure, low power, los cost Used in billions of devices: mobile phones,

    computers medical devices, home entertainment,

    Bluetooth technology

  • Bluetooth technology

    Range (distance) Class 3 : range up to 1 meter Class 2 radios : most commonly found in mobile devices, range

    of 10 meters Class 1 radios: used primarily in industrial use cases, range of

    100 meters

  • Radio Frequency Iden2fica2on (RFID)

    Wireless use of electromagne1c fields to transfer data, iden1fying and tracking tags aXached to objects. The tags contain electronically stored informa1on.

    Tags are powered by - Electromagne1c induc1on from magne1c fields produced near

    the reader. - From the interroga1ng radio waves (passive) - local power source such as a baXery and may operate at

    hundreds of meters from the reader.

  • Radio Frequency Iden2fica2on (RFID)

    Wireless use of electromagne1c fields to transfer data, iden1fying and tracking tags aXached to objects. The tags contain electronically stored informa1on.

    Tag Reader

  • Radio Frequency Iden2fica2on (RFID)

    Consists of tags and readers bi-direc1onal It follows the electronic product code (EPC) protocol It can operate with other technologies (ZigBee, Wi-Fi..) Operates under a wide range of frequency (120 kHz - 10 GHz )

    Used in home area network applica1ons such as energy management systems, door locks, ligh1ng control

  • 6LoWPAN

    IPv6 Low power Wireless Personal Area Networks Created for the Internet of Things Every node has its own IPv6 address, allowing it to connect

    directly to the Internet using open standards.
