Connected Devices

ITDev has an excellent track record in designing communications schemes and making technology choices in this area.

We have a deep knowledge of Internet protocols from SMTP to SOAP and can utilise these existing standards to rapidly develop a solution.

We apply the latest standards of modularisation, testing and design for security to our communications work.

Custom Protocols

For systems with low resources, where good performance is needed, a custom protocol may be the correct choice. ITDev can help with:

• Choice of packet or stream based systems
• Mapping data into a suitable representation
• Analysis of states, timing, concurrency and race conditions
• Implementing standard network layering using the OSI model
• Security
• Unit testing, documentation and verification
• Performance testing

Often our custom protocols are built on a common base such as:

• The socket programming interface
• USB
• I²C

Protocol Implementation

ITDev has created a virtual network model using embedded Linux to facilitate the development of next generation TCP/IP queueing algorithms, for enhanced quality of service (QoS).

We have partnered with a company to develop firmware implementing the IEEE 802.15.4 specification for building ultra low-power digital radio networks using the Zigbee standard.

We have worked with companies deploying the latest RFID technology into wireless data measurement and location devices.

Relevant Communications Standards

• IEEE 802.15.4
• Zigbee
• TCP/IP and UDP
• HTML, CSS and JavaScript
• DNS
• SOAP (an XML based protocol for delivering web services)
