Research

The main objective of PAL is to study the impact of future healthcare services on current and future communication infrastructures.

For this we plan to:

  • Develop lifestyle management solutions that focus both on preventive as well as assisted living aspects
  • Provide ICT infrastructures which provide better support for anytime-anywhere services in a cost effective manner based on current and emerging platforms
  • Demonstrate the benefits of such solutions.

The project is driven by a clear platform-oriented vision, in which user and system requirements specific to the area of lifestyle monitoring and assisted living are used to carefully extend capabilities of the underlying platform and prototyping novel concepts in a realistic setting.

The platform work can be divided into information-centric environment and communication environment.

The information-centric environment deals with information gathering, processing, presentation and governance and we are currently developing various solutions to address all these aspects. Our efforts span from sensing to middleware to human-computer interfaces and interactions. Our work is informed by various user-centric scenarios that span from preventive healthcare to emergency situations. The system developed for addressing preventive scenarios is described in this presentation.

The development of the communication environment takes a two-pronged approach, by considering the impact that future healthcare services, described through our scenarios,  pose on evolutionary (i.e., IP-based) and exploratory (i.e., pub/sub solutions developed in EU-funded project PSIRP and its successor PURSUIT) infrastructure solutions.

Building on work performed in the TSB-funded HIPNet project,  innovative traffic engineering concepts are developed and enhanced to ensure the end-to-end integrity of a connection for a user both at home and away from home, through performing network selection modelling and algorithm development for predicting handover instances and deciding how and when to handover. We also investigate effective methods for dynamic traffic engineering or service adaptation with the ability to demonstrate session robustness even in the presence of excessive background traffic.

The concept of information-centric networking (IN) started in the EU-funded project PSIRP  and further developed in PURSUIT are studied with the potential of using available resources better, of reacting more dynamically to changes in the environment and in user behaviour, and of simplifying information governance in the network layers (e.g., through policy-based information flow selection).
