Update - Sep 2013

I have recently moved to the University of Kent, UK as a Lecturer (Assistant Professor) in Ubiquitous computing, at the School of Engineering and Digital Arts.
I am looking for good research students to work on people-centric and mobile sensing, internet of things, and wireless sensor networks. If you are interested, please feel free to contact me.

FRESNEL: Federated Secure Sensor Network Laboratory

Wireless sensor networks are more and more seen as a solution to large-scale tracking and monitoring applications. The deployment and management of these networks, however, is handled by a central controlling entity and the sensor network is often dedicated to a single application. We argue that this is due to the fact that we do not yet have the means to deal with a secure multi-purpose federated sensor network, running different applications in parallel and able to reconfigure dynamically to run others.

With FRESNEL we aim to build a large scale federated sensor network framework with multiple applications sharing the same resources. We want to guarantee a reliable intra-application communication as well as a scalable and distributed management infrastructure. Orthogonally, privacy and application security should also be maintained.

Past Projects

NEMO: Networked Embedded Models and Memories of Physical Work Activity

The NEMO project is an EPSRC-funded collaborative effort by the Departments of Computing, Management Science and Psychology at Lancaster University aimed at the inter-disciplinary investigation of ubiquitous computing technologies and embedded wireless systems for industrial workplaces. The focal point of the project is the development and use of ‘smart artefacts’, i.e. work-related objects such as tools and containers augmented with embedded computing, sensing and wireless communication capabilities.

As part of the NEMO project I developed a system for monitoring workers' exposure to hand-arm vibrations by deploying embedded wireless sensors in road maintenance sites.

e-Campus: A Research Network of Public Displays

The Lancaster University e-Campus project is developing a campus wide infrastructure of public displays designed to enhance campus life and to provide a research infrastructure for new applications on public networked displays. To date they have deployed over 50 displays ranging from small 'door plate' displays, through 40inch LCD panels up to 40foot wall displays on highly visible locations throughout the campus of the Lancaster University. Each display is equipped with at least one Bluetooth scanner and can be modified to support multiple sensing devices such as cameras or microphones.

The system provides a software platform, which enables content creators to develop own applications and experiments. As all displays are networked, they can investigate media experiences that span multiple displays over a wide area.

GUIDE: Context-Aware Electronic Tourist Guide

The GUIDE project is developing hand-held computer based tourist GUIDEs for visitors to Lancaster. These GUIDEs are context-sensitive. In other words, they have knowledge of their physical location and their user's preferences. They can use this knowledge to display information and perform services specific to both a user and a location. For example, if a user is interested in history, the GUIDE unit is able to construct a walking tour which takes account of this interest. The unit gives the user directions on how to get from one location to the next. As the user arrives at each destination the unit describes what is being seen from a historical perspective.

Interfaces & Infrastructure for Mobile Multimedia Applications

Mobile environments are characterized by frequent and sudden changes in both context and resource availability. While existing systems have focused on supporting adaptation to changes in resource constraints or contextual-awareness, in this project we focused on obtaining insights into the design and implementation of an infrastructure platform that would handle both types of variation with equal ease. To explore these ideas further we developed a prototype platform designed to meet the above requirements. Within this platform adaptation mechanisms and policies are decoupled and, furthermore, mechanisms can be exposed and externalised in order to enable control by independent entities. The basic functionality of the architecture is two-fold. Firstly, it provides a repository for representations of application functionality and, secondly, it coordinates the behaviour of applications according to user defined policies.
