A Topology Control Approach to Using Directional Antennas in Wireless Mesh Networks

Overview Directional antennas in wireless mesh networks can improve spatial reuse. However, using them effectively needs specialized protocol support at the MAC layer, which is always not practical. The work discussed in this paper presents a topology control approach to effectively using directional antennas with legacy MAC layer protocols such as IEEE 802.11. The idea is to use multiple directional antennas on each node and orient them appropriately to create low interference topologies while maintaining network connectivity. The approach is based on a well-known approximation algorithm to compute minimum degree spanning trees. It is shown via empirical studies that this approach can reduce interference significantly without increasing stretch factors to any appreciable extent.

The Ovum View: The wireless LAN security nightmare

IEEE 802.11 systems have a range of at least 100 metres from a transmitter. Wireless LAN, whether based on the IEEE 802.11 or the Bluetooth standard, is a security nightmare. 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?
