Of all the personal computers to be unwrapped during the holiday season, more than 80 percent will be used to go online and search the Web's more than 92 million gigabytes of data (comparable to a 2 billion-volume encyclopedia). Getting online is the easy part, finding a useful Web page is a bit harder—keeping track of a useful Web page is another issue altogether.

People have devised many tricks—such as sending e-mails to themselves or jotting on sticky notes—for keeping track of Web pages, but William Jones and Harry Bruce at the University of Washington's Information School and Susan Dumais of Microsoft Research have found that often people don't use any of them when it comes time to revisit a Web page. Instead, they rely on their ability to find the Web page all over again.

Sascha Meinrath of CUWiN offers his follow-up on previous posts about mesh networking's scalability and utility: Continuing a conversation that began back here, and continued here, open-source and world-wide community mesh networking developer Sascha Meinrath replies and elaborates on those posts. Sascha writes: Chari is right on the mark with his clarifications on network performance degradation rates. The case I had made purposefully oversimplified the throughput degeneration rate. However, in real-world deployments, the actual throughput of a network probably degrades at somewhere between 1/n and (1/2)^n -- where n is the number of hops. Think of these two equations as two limits of the probable degradation rate; as anyone graphing these functions can see, they map an increasingly wide area of probable degradation rates as the number of hops increases -- representing an increasingly large "unknown". The point is that exact throughput degradation rates are fairly impossible to pin down because the variables that need to be taken into account differ by locale. As anyone who has done numerous real-world implementations will attest, bizarre confluences of factors can sometimes cause unanticipated outcomes and disruptions. One of the major problems facing wireless deployers is that almost all research has been conducted either via computer simulations or in "in-vivo" deployments that are highly contrived (often within science buildings or even within single laboratories). This research provides extremely useful guidelines for anticipating problems; but often fails to capture the complexity of deployments in the community. A closer-to-life example of "real-world" usage is MIT's roofnet project, whose deployment is being used to help proof the ETX route prioritization metric that is being integrated into CUWiN's software. However, this network is utilized mainly by computer science students, who are not exactly representative of the population at-large. Nitin Vaidya's work has made tremendous strides in our understanding of ad-hoc and multi-hop networks (which Chari does well to point out); but what is really needed is a truly community-based network (with all the attendant messiness) that can be utilized to explore the real-world limits of wireless networks. It is with this goal in mind that Nitin, David Young (CUWiN's technical lead), and I co-wrote an NSF grant proposal entitled, "Engineering Community Wireless Networks" earlier this year. For companies and entrepreneurs working on wireless networking solutions, the possibility of gaining real-world data is extremely valuable. Likewise, for those of us working on Community Wireless Networking solutions, these data...

New Kevin Sites dispatch from Iraq:

New Kevin Sites dispatch from Iraq:
Dirty for Dirty 06/01/2004 02:09 PM
NBC combat correspondent and weblogger Kevin Sites is in Iraq today. He's just posted a new entry on his blog -- a series of interviews with American soldiers.

[O]nce they finally do get home--they will still be faced with the complex task of finding their way in a civilian society again. And while they're eager to leave their weapons and Kevlar behind, the violence they've experienced here will likely be with them in one way or another, always.

Derek Ellyson says his memories have already hardened, fixed in his mind. "You never forget the faces. I can describe to you every dead person I've seen out here. What their faces looked like, the position they were laying in." Sorokin agrees, "War brings a lot of ugly things, you see a lot of ugly things you see other people dead and sometimes when you see somebody dead you see the face of death--the way the guy died. It could be an enemy it could be an ally it doesn't matter."

Yet living with those images of death is part of the job--the same one that requires them to pull the trigger. Before going to war soldiers have always had to ask themselves if they'd be willing to die for their cause. But there is a second part to that question which for some, is more difficult to answer: would they kill for it? For most if not all in the 3rd Platoon--the question is already moot.

Pronto, Tropos Team Up

Pronto, Tropos Team Up 08/02/2004 12:12 PM
"Dating" in two cities turns into serious relationship between Tropos and Pronto: It's a natural partnership, and one we expect to see more of as metropolitan area networks or larger hot zones develop. Pronto handles the back-end and the front-end: user experience, account management, authentication, and other details of sessions. Tropos builds the infrastructure, maintaining the hardware. Neither company should specialize in each other's fields. This kind of strategic relationship could, of course, lead to firms that have separate managed services divisions through mergers and acquisitions so that they can offer equally good infastructure and AAA support. Many of the hotspot operators provide the back-end and the build-out, like Wayport, but the scale they're supporting is building-wide, not city-wide (yet)....

A study group was formed last week to look at the possibility of creating a standard for wireless mesh networking: Intel and Cisco were some of the first proponents of a mesh standard. FireTide, BelAir, Tropos, Strix, and MeshNetworking are a few companies already delivering mesh products. The formation of a study group is just the first step in determining whether a standard is even necessary, so the formation of an actual task group that hammers out a standard is still in the distance....

New Take on Mesh Networking

New Take on Mesh Networking 11/10/2003 10:54 PM
A company called PacketHop is working on a mesh technology that routes packets among clients: Instead of routing traffic from one AP to the next, it routes from one user device to the next. The technology is designed to allow users to access a network from farther away from an AP. It looks like PacketHop is announcing that it acquired some patents from SRI International which has already done some development of a product. It's not clear when this product will be available. (FireTide has also licensed SRI patents for its products, which include a few mesh-like attributes.)...

Titanium Mesh Titties

Titanium Mesh Titties 07/01/2004 10:48 AM

While metallic pleasure bots are high, high up on the lists of gadgets we'd like to see in the near future, we're not so sure that implanting titanium mesh under the breasts of women is the way to get the party started. Nein, der boobenkreiger ist gut, says Dr. Ziya Saylan, a German doctor who has developed the technique that over two dozen women have already tried. The idea is that the titanium will hold up the huge breast implants, preventing the sagging that many older women are getting implants to correct in the first place. If anyone has a picture of the implants, we'd love to see them (outside of the breasts, if you please).

Update: Reader Stoffel Van Eeckhoudt sent this link to the home page of the procedure that has ample pictures of both the mesh and of women's breasts both before and after the procedure. It's NSFW, unless you work in a country where the sight of womens' jububbles doesn't cause enduring national scandal.

Do Mesh Networks Scale? Two Views

Do Mesh Networks Scale? Two Views 07/06/2004 03:22 PM
The head of a mesh company argues mesh networks don't scale -- and one of the folks behind an open-source mesh software project examines the argument: MeshDynamics sells a multiple-radio solution for mesh networking, and the head of the firm wrote a brief article explaining why single-radio mesh networks can't work beyond a very small deployment. I asked Sascha Meinrath of the CUWiN project for his feedback on Francis daCosta's comments. Sascha writes: While I do think that Francis daCosta brings up some potential pitfalls to wireless mesh networks, the doomsday picture he presents is based on a flawed understanding of how mesh networking topographies work. I'll explain below: deCosta wrote: 1- Radio is a shared medium and forces everyone to stay silent while one person holds the stage. Wired networks, on the other hand, can and do hold multiple simultaneous conversations. 2- In a single radio ad hoc mesh network, the best you can do is (1/2)^^n at each hop. So in a multi hop mesh network, the Max available bandwidth available to you degrades at the rate of 1/2, 1/4, 1/8. By the time you are 4 hops away the max you can get is 1/16 of the total available bandwidth. This problem exists only when all tranceivers within a mesh topography "see" each other. And herein is the flaw in the argument. Within a mesh network Request To Sends (RTSs) do silence nodes within range; however this degradation moves in waves--so if part of a mesh consisted of 7 nodes (of which G is connected to the Internet): A-----------------> ------B-----------------> ------------C-----------------> | Internet Connection Here's what would happen. A would pass a packet to B; when B passed a packet to C, A couldn't talk--thus the 1/2 reduction in throughput; when C passed it to D, the same problem would occur for both A & B (thus a 1/4 throughput); likewise for D to E (because D would silence A, B, & C), thus a 1/8th throughput. However, when E passes a packet to F, A is unaffected, when F passes a packet to G, both A & B are unaffected. Thus, in this solution, throughput would theoretically max out at 1/8th (which is probably still much more throughput than the average Internet connection--where the usual bottleneck resides). What this really points to is the need for power control in radios (which is something that CUWiN wants...

Leaders from Intel and Cisco are trying to start up an effort to standardize 802.11 mesh networking : This is a great idea, but one that not surprisingly isn't supported by current developers of mesh networks. Those companies, including Strix, Firetide, and BelAir argue such an effort would be too difficult. They might prefer not to have standards so that customers must buy entire networks from one vendor. Intel apparently is working on a mesh standard that could span 802.11 and ultrawideband networks. That sounds like quite a challenge....

In addition, the Opera House donated an AP to the town of Los Gatos to provide Internet access to the town plaza located across the street. Firetide caters to challenging deployments that are difficult to wire because Firetide uses 802.11 radios for backhaul. The release doesn't seem to be posted yet but should be here at some point. Strix is another vendor that uses wireless for backhaul. These vendors should be attractive to the cases where wiring is really difficult, like old buildings on college campuses or downtown....
