Research

My research interests are in the area of mobile and wireless computing, specifically on providing continuous (or nearly continuous) Internet connectivity to portable computing devices (including laptops, PDAs etc.) and thus enable as unimpeded communication capabilities as possible to mobile users. My focus is on architecture and protocol issues in mobile networking. I have been working on utilizing Mobile IP as an essential building block for supporting mobile instant communication.

I am also interested in facilitating network communications among computing devices in the vicinity of each other even in the absence of connectivity to the Internet. There is more to it than the ad hoc networking we commonly talk about. I would call it a combination of Computer-assisted Human Interaction and Human-mediated Computer Networking. I gave a presentation about this side interest at our group meeting.

Projects

A Linux implementation of the Mobile IP protocol, with a number of enhanced features.

Mobile People Architecture

Web Goodies

Windows/Linux dual boot

If you add a new hard disk drive and the disk on which Windows was installed becomes the second hard disk drive, Windows won't be able to boot properly with lilo unless you make the following changes.

Phdisk for Sony VAIO

Do you have trouble in recovering this "Save to Disk Preparation Utility" by Phoenix Technologies Ltd. in order to get hibernation to work again? I have put up this utility here in the hope that it can save others with similar needs some trouble. It works with VAIO PCG-Z505SX.
