I have been a Principal Lecturer at the University of Portsmouth since 2002 and I am the Course Leader for the online MSc in Cyber Security and Digital Forensics.
I have been researching parallel and distributed systems since 1987. My research interests include multithreaded architectures; mobile networks and business process modelling; parallel and distributed processing; wireless networks and sensor networks; network security; embedded systems; simulation and modeling; and mobile intelligent agent technology.
Since joining the University of Portsmouth, my work has been focused on mobile agent architecture for fault management and detection in conventional and wireless networks. Our research has shown that statistical filtering approaches are more interesting than artificial intelligent methods for fault detection based on mobile agents.
Developing a multithreaded simulation called MPA to analyse and visualise the internal execution of threads inside a CPU. I conceived a simulator based on a novel approach for a discrete simulation event environment. This approach is used by my PhD students to model and simulate networks’ performance
Contributing to the Quality of Service (QoS) in WiFi systems by suggesting several protocols that proved to be quite efficient for high QoS in wireless networks. The work has progressed to the classification of faults in the network. Currently, we are applying artificial intelligence techniques such as clustering to classify faults
Contributing to our knowledge on how to engineer robust routing systems using self-organising location servers with a project concerned with routing in large-scale ad hoc networks
