Building Mobile P2P Networks On-the-Fly

By Mark Long -- e-inSITE

MeshNetworks has come a long way since the company conducted its initial tests in Maitland, Florida last year of a new technology that can build ad-hoc, peer-to-peer networks anytime, anywhere, and with no network infrastructure in sight.

The FCC was so impressed with the roaming capabilities of the MeshNetworks platform that it awarded the company an experimental license in January of this year under which the company has been demonstrating the technology in various cities around the country.

Last March, the company's high-tech road show steamrolled into Orlando, where MeshNetworks demonstrated its high-tech platform to CTIA Wireless 2002 exhibition attendees. The demo took place in a "Lynx" Orlando transportation system bus that had been converted into a high-speed wireless multimedia showcase that included a fully operational mobile 802.11 network on the bus itself. While rolling down the highway, attendees shot off e-mails, surfed the Internet and then kicked back to enjoy streaming music videos. (See "On The Bus at CTIA Wireless 2002 .")

When the month of June rolled around, Fujitsu Microelectronics America (FMA) began rolling out the first units of a new ASIC for enabling the MeshNetworks mobile broadband platform. Fabricated in Fujitsu's 0.18-micron CMOS process, the single-chip baseband processor/MAC offering provides the modem and networking functions for the MeshNetworks system elements to be incorporated within any mobile device (see below). According to MeshNetworks, mobile users equipped with the company's ASIC-enabled PC card will be able to achieve data rates that are equal to, or even exceed, the performance of competing DSL and cable modem technologies.

P2P’s Next Frontier?

By David L. Margulius

JUST WHEN IT seemed peer-to-peer architectures might fade into the sunset, another horizon opens up.

Spurred by the spread of 802.11 and related protocols, new mobile and wireless applications are creating situations in which the lack of access to central servers offers opportunities uniquely suited to p-to-p.

Picture this scenario: A group of firefighters, responding to a crisis, surrounds a large burning building in a remote rural area while carrying peer-enabled digital voice and data communication devices. Despite lacking access to external networks or central switches, they're able to communicate via voice and video with a powerful, built on the fly, p-to-p digital network infrastructure.

Sound far-fetched? Then consider a group of management consultants sitting in a client's conference room, all equipped with Wi-Fi cards but with no access to their client's LAN or the public Internet.

Then there are applications where the peer nodes are mobile -- such as in vehicles -- and it is more efficient to connect them to one another rather than utilize a fixed infrastructure. There are also distributed devices that are economically inefficient to connect via a fixed infrastructure, such as remote sensors, traffic lights, or pipeline valves along hundreds of miles of pipeline.

New Campus Software Allows Free File Sharing

By Preeti Sukerkar

Since Northwestern blocked access to the file-sharing application Napster in 1999 because it took up too much bandwidth, students have feared that similar programs would get too popular and suffer the same fate.

But an administrator assured students these programs will not be shut down by NU.

The latest file-sharing software is Gnucleus, a peer-to-peer media program that allows users to set up a small network and significantly increase the speed of file transfers.

Many students excited about Gnucleus' prospects as an NU-specific file-sharing program are being protective -- those aware of Gnucleus declined to comment for a story, fearing the program would be terminated.

Tom Board, director of technology support services, said peer-to-peer programs do not get completely shut down on campus. Instead, they are categorized with similar programs and allotted bandwidth.
