  • Competition Funded Project (European/UK Students Only)
This research project is one of a number of projects at this institution. It is in competition for funding with one or more of these projects. Usually the project which receives the best applicant will be awarded the funding. The funding is available to citizens of a number of European countries (including the UK). In most cases this will include all EU nationals. However full funding may not be available to all applicants and you should read the full department and project details for further information.

Project description

A Wireless Sensor Network (WSN) refers to a collection of low-power
wireless devices connected through radio communication facilities. These
devices have limited processing speed, storage capacity, and communication
bandwidth. They can be deployed in a distributed environment sensing,
monitoring or collecting data, processing and communicating the data and
coordinating actions with other peers or nodes at a higher hierarchy in a
infrastructural setting. Such WSNs have a wide range of potential
applications including utilities, transportation system automation, and
patients? medical condition monitoring, etc. Some of these application
areas impose stringent privacy and security requirements on data
transmissions, processing and management.

Assuming reliable cryptographic techniques can be used to provide
communication security, it is not clear how data privacy could be
preserved in such a context. In addition, cryptographic techniques are
computationally expensive, and inappropriate use of these techniques could
lead to excessive computing power and energy consumption. The aim of this
Ph.D. project is to investigate and research efficient and cost-effective
measures to achieve security and preserve privacy in a WSN environment.
