TCP Dynamics Over IEEE 802.11e WLANs: Modeling and Throughput Enhancement

Tags:
wireless lan

Overview Today, IEEE 802.11 Wireless LAN (WLAN) has become a prevailing solution for broadband wireless Internet access while Transport Control Protocol (TCP) is the dominant transport protocol in the Internet. It is known that, in an infrastructure-based WLAN with multiple stations carrying long-lived TCP flows, the number of stations that are actively contending to access the channel is very small. Therefore, the aggregate TCP throughput is basically independent of the total number of stations. This phenomenon is due to the closed-loop nature of TCP flow control and the bottleneck downlink (i.e., AP-to-station) transmissions in infrastructure-based WLANs. This paper conducts a rigorous, comprehensive analysis of the TCP dynamics over the 802.11e EDCA.

Telco-friendly Ethernet 'ready for action'

All that is set to change with the advent of carrier-class Ethernet services and transport. The MEF's E-Line and E-LAN standards - currently being voted on - will allow service providers to adopt Ethernet, said Chen.

Peter Cochrane's Uncommon Sense: Trusting people and self-organisation

You can engineer mass transit between major/super nodes (cities), and between some minor nodes (districts and metro stations), but then you need total freedom of action to complete the journey. In each I attempt to traverse the station floor...

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?
