Challenges for future mobility systems

3

▶ Integration of automotive with heterogeneous subsystems and complex societal dynamics

▶ Highly networked, time coordinated interactions with highest degrees of assurance and safety

▶ Increasing complexity of V2X systems demand distributed computing with massive data

Architectures that allow development, deployment and maintainability of services

- Open Interfaces- Adaptive - Real-time- Dynamic

▶ Automotive and roadside gateways (Fog) can host and compose services

▶ A unifying platform is required to seamlessly interconnect in-vehicle servers with the fog, cloud and IOT.

Need for a shift in computing paradigm


Accessor: An actor based paradigm

▶ Accessor provides access to device or service by exposing only the interface

▶ Service implementation is abstracted

▶ Sequence of requests for a service (a stream) triggers a sequence of responses

▶ Composable with other actors

Actor Accessor Actor

Application runs on accessor platform in vehicle gateway

request response

Service implementation

Runs on a device or cloud (in this case)

Data stream or timestamped events

▶ Application execution controlled by accessor model of computation

This is the essence of accessors, a design pattern that embraces concurrency, asynchrony, and atomicity.


A novel candidate: Accessor platform

6

Collaborators

▶ Directly connects to heterogeneous things and services within and outside the vehicle

▶ Scalable and dynamic services can be developed and deployed using flow based design.

▶ Dynamic Composability of accessors facilitate service adaptability based on context/environment

▶ Allows distributed computing with fog or cloud for time-critical, data and processor-intensive applications

Model based design environment for service modeling

▶ Newer services can be built using the service components of the accessor library

▶ In built timing guarantees made possible from a few decades of work in Models of Computation (MoCs)

▶ Code generation for target hardware

▶ Accessors for different devices/service to be developed.

Similar to other flow based design approaches


A Telematics application using Accessors

Traditional approach

▶ Different services relying on OBD data utilize data pushed to the cloud.

▶ Services lie outside the scope of the vehicle.

▶ OBD accessor is used to create such services that rely on vehicular data

▶ Same application can run in a vehicle gateway or user`s mobile phone – interoperability!

A case for integrating Accessor with Adaptive AUTOSAR*

▶ Model based tools to design and rapidly develop diverse services with application level time guarantees

▶ Reuse IT standards as much as possible at the application level

▶ Development of ARA applications will become easier, apart from extending the scope beyond infotainment

▶ Adaptive AUTOSAR architecture allows us to interconnect both platforms


Current work

11

▶ Accessor platform (in both node.js and Java) can itself run as an adaptive application or as a stand alone non-AUTOSAR application

▶ Make sample ARA services available in the accessor library

▶ Accessor-level services utilize time and execution management APIs to achieve deterministic temporal semantics

Accessor Platform Architecture


Some more current work

12

▶ Developing SOME/IP accessor (subscriber and notifier) to interface accessor applications with adaptive autosar applications

▶ An accessor application to switch between and detect new cameras utilizes SOME/IP accessor

▶ Mechanisms to utilize ARA APIs should be developed by extending SOME/IP accessor interface design

Conclusion

13

▶ We share our early stage work on a new connected car platform that could supplement Adaptive AUTOSAR goals.

▶ Accessor platform▶ Uniform device/service interfaces with underlying module implementations for

heterogeneous environments ▶ Extends the scope of services residing within the vehicle to edge and cloud▶ Greatly reduced development time in a model based environment with code

generation for target hardware▶ Dynamic and adaptive services that can run untrusted code from remote services

(eg. City infrastructure)
