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.

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

CPS Integration
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.

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.
