Joint Optimal Channel Assignment and Congestion Control for Multi-Channel Wireless Mesh Networks

Overview The aggregate capacity of wireless mesh networks can be increased by the use of multiple channels. Stationary wireless routers are equipped with multiple Network Interface Cards (NICs). Each NIC is assigned with a distinct frequency channel. This paper formulates the Joint Optimal Channel Assignment and Congestion Control (JOCAC) as a decentralized utility maximization problem with constraints that arise from the interference of the neighboring transmissions. Unlike other previous work, the JOCAC algorithm is able to assign not only the non-overlapping (orthogonal) channels, but also the partially-overlapping channels within the IEEE 802.11 frequency bands.

The Ovum View: The wireless LAN security nightmare

Wireless LAN, whether based on the IEEE 802.11 or the Bluetooth standard, is a security nightmare. IEEE 802.11 systems have a range of at least 100 metres from a transmitter. The industry and its customers are waiting on the standards community and...

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?
