Modelling TCP Flows Over an 802.11 Wireless LAN

Tags:
wireless lan

Overview This paper presents an analysis of the throughput of TCP flows transmitted over IEEE 802.11 wireless LAN connections, for the case when TCP flow control is restricted by the receivers' advertised windows. Both persistent and non-persistent TCP connections are considered. The paper obtains an expression for the aggregate TCP throughput of multiple persistent TCP connections, and then uses this result in a queueing model of non-persistent TCP connections. The theoretical models are validated with simulation. Results show that the total bandwidth is shared fairly between TCP flows, and that the aggregate TCP throughput is insensitive to the number of flows.

Time for the wireless, networked laptop

Mobile phone operators are among those who realise this, and they've been offering wireless internet connections to laptop users for a while. Using wireless connections for laptops is as sensible as using wireless technology for mobile phones.

Wi-Fi fights back against WiMax with 100Mbps

A standards body is set to ratify 802.11n by September next year, giving Wi-Fi a throughput of 100Mbps and helping to bolster its potential uses in bandwidth-heavy situations. Wireless LAN has really moved to business critical," he said.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
