Project Description

This PhD project tackles scientific issues aimed at creating and laying the mathematical foundations of an innovative Wireless IoT Communication System that is reliable (information arrives), fast and light (less power, less hardware, less computation, higher bit rates), universal (to mainly function underwater, but also appropriated to other wireless media), secure (not disclosing information to untrusted agents).

This PhD project will be separated in 2 main scientific challenges. The first challenge will be to understand under which conditions and configurations chaotic signals propagating in non-ideal channels can naturally support networked underwater communication systems involving several agents. The innovation here is to extend previous works that have shown the use of chaos for communication systems involving two agents in ideal channels to networked communication in the non-ideal channel. The second challenge is focused on network communication in non-ideal channels with trusted agents, knowledge required for the creation of the IoT Communication chaos-based system proposed. In the non-ideal channel, the received signal is a composition by interference of strongly distorted signals coming from several transmitters and propagating over several paths. The goal is to show that fast and light neural networks can be trained to recover information from a unique trusted transmitter, potentially enable “smart” data analytics about the information received. Communication can be done only by the trusted agents who know specifics of the training, knowledge that will provide support for the creation of a secure IoT communication system.

Candidates should have (or expect to achieve) a UK honours degree at 2.1 or above (or equivalent) in Natural and Computing Sciences, Mathematics or Engineering.

Preference will be given for students who have also expertise in one or more of the following topics: Communication systems, theory of Dynamical Systems, Information theory, Synchronisation.
