Brief Introduction
About us
Emertxe (http://www.emertxe.com) is India’s one of the top IT finishing
schools & self learning kits provider. Our primary focus is on Embedded
with diversification focus on IT applications.
Our product division works on IoT based solutions with major focus in
Embedded aspect by focusing on the following areas:
• Hardware design
• Product engineering, integration and solutions
• Linux porting and turning
• Embedded application development
As an organization we have two fold vision:
• Contribute to education by minimizing industry-academia gap
• Build meaningful solutions to solve common problems
• That’s what we say “Make life easier”
Its big and real
IoT: Any TIME, Any THING, Any PLACE connection
Its your things
Your Things = Embedded Technologies, Your Data = Data Science

IoT layering
IoT layering
Application layer
(How data gives meaning?)
Cloud data
(How the data is stored?)
Network-Service edge
(How the device is connected to the Network?)
Embedded: Devices & sensors
(where and what to sense?)

Design challenges
C1: Stability of network
Challenge:
• Deploying IoT products in network unstable (ex: Poor GSM / GPRS signals) environment creates issues
Factors:
• Link speed
• Link stability
• SW state machine
• Asynchronous conditions
Resolution:
• Boundary value tuning
• Algorithm enhancement
• Dynamic detection
C2: Power management
Challenge:
• Overall power consumption by sensory nodes in IoT should be minimal, should consider fluctuations as well
Factors:
• Minimalistic power need
• Higher power backup
• Power fluctuations
• Power failure recovery
Resolution:
• Component selection
• SW turning
C3: Network failover &
Memory management
Challenge:
• During network failover, internal non-volatile memory should store critical data
Factors:
• Network outage
• Fleet management
• Optimization
• Cost implications
Resolution:
• Decision making in NVM
• Choosing right memory and data structure
• NOR instead of NAND
• Creating secondary partition for failover handling
C4: OS optimization &
Tuning
Challenge:
• In case of IoT devices running OS (Ex: Embedded Linux) optimizing and tuning provides challenges
Factors:
• Open source usage
• Unsupported peripherals
• Size requirements
• Performance requirements (ex: Boot time)
Resolution:
• Custom device drivers
• Open source size reduction techniques
• Tuning Kernel subsystems
C5: Non-functional
requirements
Challenge:
• Non functional requirements puts up a lot of challenges during design phase
Factors:
• Product casing
• Form factor
• EMI
• Regulatory requirements
Resolution:
• Industrial Standards
• Good Shielding
• Component Selection, Standards and Security Protocols
Conclusion
The design phase of IoT is a very fast field with umpteen number
of challenges
Many of the common design challenges faced in Embedded field
apply to IoT as well, with some specifics
This sharing is based on our hands-on product building experience
Might vastly vary between different types of IoT devices
By having an engineering approach, many of the issues can be
resolved
