Mesh Networking Goes Industrial
News Mesh networks work using a series of nodes -- typically very small, low-cost PCs with flash disks in place of hard drives -- to extend a Wi-Fi network from a broadband cable or satellite connection over large areas.

Sun Seeks Supercomputing Glory
News Because more boxes can connect directly to the switch, processors at distant nodes don't have to leap through as many connections to communicate, according to Sun. We are looking at a factor-of-three improvement over the current best system at an...

Intel Makes A Mesh Of Wireless Networking
News The physics of wireless networks means that nodes close to each other can operate at much higher speeds, all else being equal," said Witteman. In the enterprise, mesh can be used to quickly extend the reach of a wireless LAN without having to wire...

Warchalking: London Wi-Fi Guerrillas Take Tips From Hobos
News But warchalking is remarkable because it is based on an ad hoc process of people discovering Wi-Fi nodes -- whether commercial or not -- and signalling their presence with chalk symbols. The first attempt at drawing up symbols resulted in three...

The Selfish Node: Increasing Routing Security For Mobile Ad Hoc Networks
White Papers Mobile ad hoc networking can work properly only if the participating nodes collaborate in routing and forwarding. Nodes in mobile ad hoc networks do not rely on a central infrastructure but relay packets originated by other nodes.

High-Powered Machines Are A Reality Despite Budget Constraints
White Papers Constantly faced with budgets cuts, government agencies are increasingly turning toward multiuse, scalable, and affordable cluster computers: supercomputers built by linking individual servers (nodes) together via a networking device that connects...

Improving Performance Of Wireless Ad Hoc Networks Using A Few Point-to-Point Links
White Papers The current wireless technologies such as IEEE 802.11 (Wi-Fi) make ad hoc networking viable for small regions involving a few tens of mobile nodes, but such networks are unreliable. This paper investigates the benefits of adding a few...

Improving Ad Hoc Network Performance With Backbone Topology Control
White Papers However, situations may occur where the connectivity of a set of nodes cannot be guaranteed (if they are too far apart); moreover, no QoS can be offered since the number of hops and the signal quality (thus the throughput) cannot be controlled.
