C-MAC: A Cognitive MAC Protocol for Multi-Channel Wireless Networks

Overview A number of algorithmic and protocol assumptions taken for granted in the design of existing wireless communication technologies need to be revisited in extending their scope to the new Cognitive Radio (CR) paradigm. The fact that channel availability can rapidly change over time and the need for coordinated quiet periods in order to quickly and robustly detect the presence of incumbents, are just some of the examples of the unique challenges in protocol and algorithm design for CR networks and, in particular, in the Medium Access Control (MAC) layer. With this in mind, this paper introduces a novel Cognitive MAC (C-MAC) protocol for distributed multi-channel wireless networks.

Robot guard dog invented to police Wi-Fi networks

Its designers said they're still working on the autonomous capabilities - including sensors to detect humans and obstacles - and so they used a game controller that's attached to a laptop in a backpack to manoeuvre the robot around DefCon.

SIP paves the way for seamless collaboration

A protocol called SIP gives you the ability to work closely with others in a variety of media - no matter where you are. Tim Dillon, principal analyst with Current Analysis, said: "SIP-enabled applications are ideal for workgroups where small teams...

IP poised to storm the call centre

Over the course of the next five years, IP will continue to move upmarket until IP contact centres match the size and scope of traditional TDM contact centres. It is examples such as this that show how vendor support for VoIP will ultimately...

VoIP threats to watch out for

One way for hackers to do this is through a man-in-the-middle attack, where a third party spoofs the MAC addresses of the two speaking parties, to force the IP packets to flow through the hackers' system.

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?
