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)
