Research Activities
While there are cross-cutting themes to our work such as body-centric communications, connected health, real time localisation and wireless networked control systems,
our research activities are categorized into three main 'topics':
antennas, channels and networks. We are also increasingly involved in security applications of wireless networks.
Not all details are listed here so navigate using the research activities sub-menu or click on the links below find out more.
Wearable and integrated antennas research
Bodyworn and compact antenna design ranging from medical implant antennas to highly efficient antennas for over the body surface communication to single-feed switchable patch antennas for controlling on- and off-body propagation.- High-efficiency low-profile antennas for wireless body area networks
- Beam switching stacked patch antenna at 2.45 GHz
- Electrically small low-profile wearable patch antenna for 868 MHz
- Tissue coupled UHF antennas for medical implants
- RF safety, bioelectromagnetic modelling and low-SAR antennas
Wireless channels and radiowave propagation research
Channel characterisation and modelling with a particular emphasis on human body effects on wireless systems.- Next generation body centric communications
- Channel modelling and characterisation for wireless body area networks
- Off-body UWB channel characterisation
- Wireless body-centric communications in populated environments
- smart antenna / MIMO channel and capacity modelling
- dynamic channel simulation for both ends mobile scenarios
Networks research projects
Our focus is on networking & protocols for short range wireless links and our approach is to start from the perspective of the wireless channel.- Body area networks for interactive wireless environments
- ad-hoc body-area networks for medical devices
- Wireless Interconnectivity and Control of Active Systems (WICAS)
- pointer controlled slot access & resynchronisation (PCSAR) protocol for low power centralised wireless access

- Protocols for Wireless Networked Control Systems (WNCS)
- Ultra low power active RFID based patient tracking
Security research projects
These activities are focused on two broad areas: tracking and localisation (physical security) and joint security / energy saving protocols for short range radio applications (data security).- SATURN - Secure Ad-hoc Tracking Using RFID Networks
- Improving localisation in indoor wireless networks
- Ad-hoc body to body localisation using low power wireless nodes
- Using short-range mm-wave body to body networks for stealthy communication
- Secure, energy efficient protocols for medical implant communications
