 Piers O'Hanlon

Piers O'Hanlon's expertise is in the area of networked systems, media transport, and security. His current research is in the area of security and privacy in federated sensor networks.

Profile

Piers O'Hanlon has been involved with research into Internet based systems since the early nineties. His current research focusses on security, privacy, and congestion control. Whilst at University College London he also worked on networked multimedia transport over IPv4 and IPv6, large-scale conferencing applications, grid systems, and network testbeds. He has significant expertise in these areas, having worked on, and managed, a number of UK-, EU-, and US-funded research projects. He is an active participant in the Internet Engineering Task Force (IETF), having authored a number of standards and drafts in media transport, emergency services, and signalling areas. He has participated in the Open Grid Forum (OGF) as a working group chair, and authored a number of standards documents. He has also consulted for a number of organisations and companies.

Current projects

Past projects

  • Future Home Networks and Services

    May 2011 - April 2014

    This project is addressing home network and service security by researching and developing security frameworks for sharing between networks and devices, protocols to connect devices with cloud services, and security analysis of remote management systems.

  • FRESNEL: Federated Secure Sensor Network Laboratory

    January 2010 - April 2013

    FRESNEL aims to build a large scale federated sensor network framework with multiple applications sharing the same resources, where reliable intra-application communication is guaranteed, as well as a scalable and distributed management infrastructure.
