Seamless Roaming Between Wireless Networks (NetSwap)

This project is concerned with the research and development of a solution which would help mobile nodes to roam between different types of wireless network seamlessly.

The two wireless network protocols that are of interest in this project are 802.11b (WiFi), a wireless local area network which is increasingly being used in homes and offices, and GPRS, a wireless wide area network which works as a data extension to the GSM mobile phone network.

The project commences by researching current wireless network technologies and solutions. Subsequently the problem is discussed in further detail and a new software based solution, which would decrease network swapping errors, is proposed and documented.

The new solution, NetSwap, is implemented in network simulation software and tested against results from previous tests with encouraging results.

Literature survey for the Broadband Cable Modem Service (IEEE 802.16)

This report was written along with three other people for a University Unit Advanced Networking (ADNET) which talks about the history of cable modems, how they work, and future uses.

Cable Modems came into existence as one answer to the issue regarding the lack of bandwidth and speed available to home users. Home users traditionally used the analogue telephone system to transmit and send data across the Internet. The fastest they could connect on a standard connection was limited by the poor infrastructure (wiring etc) of a system designed to support voice communication not computer data transmission. The 56k dialup modems were the fastest achievable on such setups.

Due to the boom in cable Television, brought about in part by the deregulation of the cable television stations but the 1984 Cable Act (allowing the stations to broadcast popular sports programs etc), it is estimated that by the end of the 80's 53 million households were cable subscribers. With the infrastructure of cable already in place and cable of high speed communications via the coaxial cabling and fibre optical cables (far superior to the analogue telephone system) it is of no surprise that the Cable Modems, allowing the home user to connect to the Internet via their cable connections, proved popular and a viable success economically. The new Cable Modems allowed connections far in excess of that available on the old 56k dialups.

PlayStation Technical Specifications

This is not really a project but a bit of self interest which I thought I would put on the JLSNet website. This page shows the technical specifications for each generation of the Sony PlayStation Games Consoles, also including the future PlayStation 3.

These specifications have been gathered as a comparison between each major console in the PlayStation family, showing the progression of technology through each generation.

Comment on Blogs using Mobile Phones

Recently in my Blog I have been discussing how intergrating Mobile Phone Text Messaging and Blogs would create an interesting combination. I talked about the fun that could be had by allowing users to comment by mobile phone text messaging, it could open up a whole new area of voting polls on blogs and allow people to comment while on the move.

I soon got hooked on looking at the possibility of making this work, and it did not take me too long to come up with a basic working solution. For the rest of this document I will attempt to explain how I did this.

Cable Broadband v's ADSL Broadband
