Adam's Place in Cyberspace

Current research

My main research focus is Walkabout, which is the subject of my PhD thesis, entitled "Walkabout: An Asynchronous Messaging Architecture for Mobile Devices".

Walkabout is an architecture that provides network support for message transfer between mobile devices communicating across the Internet. In order to cope with changing addresses and device disconnections, devices send messages to each other across a peer-to-peer overlay network, via peers which are located in the same local network segments as they are. This enables them to transfer messages at local network speeds, maximising their usage of transient network connectivity. The overlay uses a transfer protocol that makes use of parallel downloads wherever possible. Messages migrate to follow destination devices as they move, and are cached when the destination is not available.
