On Optimization of CSMA/CA Based Wireless LANs: Part II - Mitigating Efficiency Loss

Overview Most current deployments of IEEE 802.11 based wireless LANs suffer from various inefficiencies arising from the interactions of MAC and Physical layers. These inefficiencies often limit network users from reaping the full potential of the high physical data rates in these systems. This paper considers optimizing these systems to mitigate, the following forms of inefficiencies: selfish users exploiting the dependency of DCF channel share achieved on the transmission strategies used, leading to inefficient operating points (Nash Equilibria), automatic rate adaptation enabled devices reducing the system throughput even for moderate loads, and, low data rate users limiting the throughput of high data rate users.

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.
