Joint Route and Power Assignment in Asynchronous Multi-Hop Wireless Networks

Overview The paper considers constructive techniques for joint route and transmits power assignment in asynchronous multi-hop wireless networks. A constrained optimization problem is formulated to maximize power efficiency of the network while enforcing a minimum signal to interference ratio at each link to ensure desired end-to-end Quality of Service (QoS). Numerical comparisons suggest that allowing a controlled level of interference may lead to better utilization of available spectrum than prohibiting interference via CSMA/CA.

News in View: Pundits fail to bond with wireless networks

But problems with interference and dead spots on wireless LANs will always be an issue, as is discussed in this week's News in View programme. Kevin Flood, chief technology officer at Tolly Research, was more cautious, admitting that interference...

Peter Cochrane's Uncommon Sense: Wireless everything

This column was typed on an Apple G4 laptop and transmitted to silicon.com via a wireless LAN using a spread spectrum signal. Sometimes this is experienced when atmospheric conditions cause unexpected interference, with signals propagating from one...

Radioactive: Bluetooth - survival of the fastest

This increases the signal's range by reducing interference. In 2002 the FCC allocated unlicensed radio spectrum from 3.1GHz to 10.6GHz for its use. The US Federal Communications Commission (FCC) currently defines UWB as a radio technology with a...

Peter Cochrane's Blog: The search for spectrum

This is the world I grew up in as a young engineer, where interference, multi-path, scatter and signal-to-noise ratio dominated all design and operational considerations. They talk to each other to minimise the energy used and problems associated...

Broadband wireless gets spectrum boost

The high bandwidth combined with narrow-beam signal technology means a very large number of broadband users can co-exist on the spectrum without interference, Ofcom said. The licences will be tradeable and licence holders themselves will be...

Peter Cochrane's Blog: Wireless jelly

For at least some of the time I think we can safely assume that the problem is plain old interference. It appears that mains- or power-feed borne interference is still getting into the environment and causing an occasional problem.

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.
