In this article, the new Constrained Access Protocol (CoAP) will be introduced and analysed for its fitness for purpose in constrained environments such as wireless sensor nodes. Iain Learmonth a member of the Electronics Research Group at the University of Aberdeen explains the CoAP protocol, for providing representational state transfer (REST) and how wireless sensor node may use these services to send sensor observation data…
In response to the biomedical industry demands for a high-accuracy, high-stability temperature sensor, Heraeus, a global and privately owned company that specializes in precious metals, materials, and technologies, sensors, biomaterials, and medical products, has developed the surface mount platinum Resistance Temperature detector (RTD) temperature sensing…
Platforms such as wireless sensor nodes are typically quite constrained in the amount of processing power, memory and battery power available. Whilst 6LoWPAN has enabled these devices to have IPv6 connectivity, the protocols that are typically deployed on top of IPv6 may not be well…
The “internet of things” that was predicted by movies, researchers and business entities could soon be with us – household objects going online and communicating with each other and people, machine to machine communication is here to stay. Even the potted plant wants to get…
London city airport has become the first commercial aviation industry in the world to test machine-to-machine communication integrated with different technologies known as Internet of Things (IoT). A modernized experience will tend to be different from the missing luggage, delayed flights, and crazy long security…
A security solution developed by Cronto that protects against Man-in-the-Browser attacks, one of the most serious threats to online banking customers, and which is responsible for millions in annual losses to the banking sector, is being rolled out across Europe by a Cambridge University spin-out.…
Why is it needed? •To predict coverage between nodes in a wireless network •Path loss is different from environment to environment, e.g., in-building is different to outdoors. •Knowledge of path loss enables system parameters to be defined, e.g.,transmit power, receiver sensitivity and antenna gains. •Path…
