Architecture Contents

Sensing Module: Data collection from physical world through sensors.

Data Management Module(DMM): Consists of the computational devices and storage media.

Next Generation Internet: Enabling applications to select the path, or paths that their packets take

between the source and destination.

Service Aware Modules (SAM): Sensed data is being recognized and sent to the services available.

Application Module (AM): Services are deployed and interact with NGI. Info is saved on database for QoS support. [NoSQL]

Sensors and Actuators: Actuator receives the commands from the Application Module, and

executes.

Security Assurance


6

How can we provide people and society with cyber-physical systems that they

can trust their lives on?

Trustworthy:

Reliable, Secure, Privacy-preserving, Usable, etc.

Security for CPS

Safety, Security and Privacy

Primary aim of all CPS design

Ensure no harm comes to the underlying physical process

Ensuring security/privacy crucial for safety

CPS are deployed in missions critical settings

Collect sensitive data and can actuate changes in the physical process

Composing individually secure systems into a composed system might not be good enough

Computation and Energy limitations .

Utilizing properties from underlying physical process might be a way to proceed

Vehicular Scenario: Service aware modules make communication and control efficient by

providing the best application in different services to a single car.

Agriculture Scenario: Greenhouse: After receiving a configuration of greenhouse by

consumer, here our feedback awareness makes network efficient tocontrol different services like watering, humidity, plant healthmonitoring etc. with real time control.

Health Scenario: Hospital: Real time monitoring and control can be achieved by Data

Management Module and Service awareness module which alsoplays an important role in order to provide QoS monitoring. Whiledesigning a system for hospital, sensitive applications are queued onthe top priority.

Open Challenges & Future Work…


11

QoS-Aware Communication Protocols: Identification of application requirement of each type of traffic. Efficiency.

Resource Management: Huge amount of dynamic data. Auto Management Techniques are required.

QoS-Aware Power Management: In CPS, dynamic computing demands much CPU energy. Minimization can be

proposed by exploiting dynamic voltage technology.

Simulation Tools: Simulation models dealing with dynamic communications.

Future Work: Implementing Proposed Architecture in Simulated/Test-bed Environments. Smart/Unifying Routing Schemes are required for Real Time sensing/actuating

devices.
