EXOSENSE
Embedded Erlang Platform
End-to-end solutions for connected devices

Monday, December 19, 2011

Feuerlabs creates embedded development
frameworks and services by integrating carrier
technologies to develop, deploy and manage
mobile devices.


Exosense Device is an open source end-to-end platform for
distributed embedded and application development.

Exosense Server provides carrier grade device management
that links costs to revenue through our hosting and licensing
plans.


Hans Vestberg, CEO at Ericsson:

“50 billion connected devices by 2020”


New thinking is required to
prepare for the embedded
future


A new set of tools are needed to utilize the multi-core CPUs
that have already arrived while covering the entire chain from
sensor to backend systems.
Distributed programming, security, traffic budgets,
conﬁguration management and fault tolerant software
versioning are no longer optional.


Meeting increasing complexity


Component Integration
A modern car has 50-60 control units, 100m+ lines of code
Next generation telematics
Raw data, deep inspection, sensor data proﬁles
Software management
Download, installation, rollback, tracking
Strains the development organization
Regression, interop tests, deployments, fault analysis, testing, deployment


Multi-coring the embedded
world


Energy consumption limits single core
Heat and power limits reached
Battery capacity increases are lacking
Adds a new dimension of software complexity
Core utilization
On-board debugging
Post-mortem analysis


Looking at telco for help


Problems we now see in embedded have been solved decades ago by telco
Distributed systems
Remote management
Code complexity
Testing
Device management
Telcos’s development strategies are adaptable to the embedded sphere
Embedded processing power is sufficient to run telco technologies
Technologies and development methods carry over


What is Exosense?


End-to-end platform


1. Exosense covers the entire chain from sensor to backend server as a single system
2. Enables seamless integration with customer supplied backend system for detailed
control
3. Handles conﬁguration data pushing and software distribution out of the box
4. Allows ad-hoc code to be distributed and executed for fault searching and deep analysis

Focus on what matters:
applications


1. Exosense collects all supported devices in a hardware abstraction layer
2. An application developer only needs to worry about one coherent messaging API
3. Erlang enables rapid prototyping and deployment
4. Blank devices can be deployed in the ﬁeld and ﬂashed over the air
5. Software can be developed independently from hardware

Multi-core advantages of
Erlang


1. Erlang handles load balancing between cores and CPUs automatically
2. Scales from single to multi-core with no code changes
3. Erlang's messaging-based strategy eliminates threading issues
4. Eases debugging on and off-board

Summary
1. An Open Source, Erlang based platform that covers the entire chain from sensor to
backend system
2. Allows an organization to focus on application development
3. Handles conﬁguration pushing, software versioning, traffic budgets and ad-hoc code
execution
4. Feuerlabs' device management hosting service provides a zero-cost start
5. Solves the multi-core problem domain once and for all


Next step


1. Obtain a demo board
2. Setup a free hosting account with Feuerlabs
3. Test the pre-installed end-to-end demo
4. Deploy your own code


Case study:
Telematics system for campus ﬂeet of 100 electric vehicles

Purpose: Collect usage data, geo-fence and monitor shared ﬂeet.

Characteristics:
1. RFID access control with real-time OTA authentication
2. Vehicle can be remotely locked/unlocked and deactivated/activated from Campus HQ
3. Vehicle GPS tracking allows for tracking while prohibiting off-campus use
4. Integrates with multiple on-board systems
5. Alerts HQ of abnormal events (curb-strike, fence breaching, system faults)
