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…

‘Internet of Things’ from ‘Internet of Confusion’ at London City Airport
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…
Security Solution For Man-in-the-Browser Attacks
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…
Radio Propagation Modelling
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…
