Impact of Interference on Multi-Hop Wireless Network Performance

Overview This paper addresses the following question: given a specific placement of wireless nodes in physical space and a specific traffic workload, what is the maximum throughput that can be supported by the resulting network? Unlike previous work that has focused on computing asymptotic performance bounds under assumptions of homogeneity or randomness in the network topology and/or workload, the authors work with any given network and workload specified as inputs. A key issue impacting performance is wireless interference between neighboring nodes. The paper models such interference using a conflict graph, and present methods for computing upper and lower bounds on the optimal throughput for the given network and workload.

What's the fuss about... storage networking?

However, the definition of virtualisation varies from manufacturer to manufacturer, from virtual physical ports on hardware, through virtual placement in a silo, to all storage assets being viewed as a single, infinitely expansible pool.

What's the fuss about... broadband communications

Even when it's up, ADSL has a reputation for non-optimal performance. What's more, a fully contended consumer ADSL line (50:1) gives a lower possible throughput than a clean 56K modem. It is all very well having 100 megabytes of storage space, for...

Oh, what a mesh!

Creating wireless internet access is cheaper with them because they use nodes that can communicate with each other to route traffic. This space is heating up," Nortel Networks general manager Mark Whitton said.

Peter Cochrane's Blog: More wireless equals more wires

In the old wireless regime we carefully planned and limited the use of space and spectrum, and often completed extensive propagation and interference trials as part of that process. In addition, the reuse of spectrum - and the control and...

Phorm defends 'traffic-analysis' methods

Nicholas Bohm, the FIPR's general counsel, said last week "the illegality stems… from the fact that the system intercepts internet traffic". The Home Office] gave an opinion, not a legal opinion, of their understanding of how the law was [to 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.
