Performance of a Distributed MAC for OFDM Based Power Line Communication Networks

Overview This paper studies the performance of a distributed Medium Access Control (MAC) scheme in an OFDM based PowerLine Communication (PLC) network. Most of the existing approaches for MAC in PLC networks consider a centralized means of allocating carriers to voice and data calls. The paper presents a distributed approach for carrier allocation where the access units choose a carrier from the set of available carriers by carrier sensing. It also shows that the model with a distributed MAC improves the over all delay performance for PLC networks with data services and it gets about a 95% reduction in the delay for data packets in a PLC system with 225 stations and 15 carriers.

Motorola CEO: Don't worry about data - milk voice

Carriers make nearly all their money from voice calls, yet they're each spending billions on building new telephone networks capable of high-speed web access. Wireless carriers, which believe such services will help dig them out of two years of...

VoIP primer: How it works - and what the jargon means

The problems of packet loss, delay and jitter are exacerbated when voice traffic intermingles with packets from other applications. When packets arrive at their destination, they can arrive in any order with significant delay.

Quocirca's Straight Talking: Are you a windscreen or a fly?

More utility is called for and it's an opportunity for utility carriers to avoid another windscreen. Mobile carrier networks are becoming more flexible and horizontally integrated with the IP Multimedia Subsystem (IMS).

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?
