Wired Mesh Networks

People have added comments that the concept is applicable also to wired networks. Whenever people refer to mesh networks, or mesh networking the mean WIRELESS mesh networking. Please provide me a single verifiable reference to where wired mesh networks have been used, and I agree this should be in the text, otherwise wired should be removed. The notion of setting dynamically setting up a wired mesh network seems to cumbersome to be of any value and would just confuse. --lanilsson

Hi

1. Please sign you comments!
2. Your new change in the introduction text is acceptable.
3. A Mesh network as you wrote "is utilizing a mesh topology, and is networking concept", I agree with you. But what network topology do WANs have? if you look a bit closer, you find meshes, Rings, stars and so on. The internet appears to be a big mesh! In so far mesh networks are not limited to wireless networks. Btw. WLANs and the last mile of mobile networks (GSM, UMTS,....) often use a star topology.
4. The articles Mesh networking and Wireless mesh network intersect. Possibly we should talk about that.

Merge with mobile ad-hoc network

The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section.

Mesh network be merged with mobile ad-hoc network? I like the idea of this. I view the mobile ad-hoc network as a type of mesh network, and should therefore be placed under the mesh network article as a sub-category of mesh networks. (the above unsigned comment was added by Matt0401)

Disagree, chiefly because of subject size. See argument on MANET talk page for why they're different subjects. There's been major research & development focusing on MANET that is not applicable to mesh networks in general. That said, material should be sorted to eliminate overlapping information. --Alvestrand 07:01, 12 February 2006 (UTC)

Also disagree MESH is a much larger subject, MANET is related to ad-hoc only

As an active researcher of both MANET and mesh networks I strongly disagree. They should be separate articles. Mesh Networks and Mobile Ad Hoc Networks both use mesh topologies, but differ in how they are envisioned to be used. Mesh Networks are commonly thought of as dynamic wireless access networks, and MANETs as stand alone networks, although the reverse is certainly possible. The main difference is the mobility in MANETs, as mesh networks can certainly be very ad hoc in nature (see wiisard.org for an example of this). --lanilsson

Links

I am totally fed up by the random deleters here who think they know more about the subject. I DO NOT agree that some mesh networking projects are here on this page and that others who do THE SAME valuable community research are randomly deleted. It is not factual! BTW: funkfeuer just recently started to continue on OLSR development (from olsr.org) after agreeing with the core maintainers to do so. This can be proven. I DO NOT AGREE with the self acclaimed editors here who just simply like to troll around and delete links to facutally and provably community projects who push the limits of mesh networking WHILE AT THE SAME TIME LEAVING OTHERS IN THE ARTICLE. Not ok, not factual. Delete all or leave the more important ones. If you dont know what is actually happing in this field , then dont edit/delete. Thanks for your understanding -- AaronKaplan

I think the issue is that there are too many external links... Wikipedia's policy is to be an encyclopedia and not a collection of external links. While it is true that there are important projects that deserve a link, we need to keep such links to a minimum. I think a good idea would be to create a new section for the article entitled "Community Projects" or something along those lines, and then insert a brief paragraph containing an external link to the community project's page for each community project? Any input on this idea? --Matt0401 17:43, 23 July 2006 (UTC)

Agree with Matt0401. Commercial and unaccredited links removed today Nelson50 15:05, 29 July 2006 (UTC)

SMesh

"Mesh networking is a subclass of mobile ad hoc networking (MANET)"

I disagree - mesh networks are not exclusively mobile, or necessarily ad-hoc.

I added a reference to SMesh. As one of its authors, I'm biased, so please, edit the paragraph if you consider it unsuitable here. ralucam 17:26, 30 May 2007 (UTC)

Generations of Mesh Networking

"There are three distinct generations of wireless mesh architectures. In the first generation one radio provides both backhaul (packet relaying) and client services (access to a laptop). In the second generation, one radio relayed packets over multiple hops while another provided client access. This significantly improved backhaul bandwidth and latency. Third generation wireless mesh products use two or more radios for the backhaul for higher bandwidth and low latency. Third generation mesh products are replacing previous generation products as more demanding applications like voice and video need to be relayed wirelessly over many hops of the mesh network."

I disagree. There are three types of Mesh networks - one radio nodes, two radio nodes and multiple radio nodes. By calling them generations, it makes it seem as if this is an evolution. It's not been that way. They're simply have been tailored for different design goals. The meshes made with single radio nodes are low cost, but suffer of latency and throughput problems. Meshes made with multiple radio nodes don't have the latency problems and are suitable for multimedia applications. Please supply a reference for this. 65.161.188.11 01:33, 6 March 2007 (UTC)

I totally disagree too with this kind of schematization of wireless mesh networks: please, provide scientific references for it. Manchoz 14:23, 11 April 2007 (UTC)

Advertisement or not

I don't think that current papges are two much included advertise information since it merely describes the state of the art technology. However, I recommend that many readers (wikipedian) participate to improve this pages more technically because the give technology is regarded as one of future technology.

Generations

Sorry about this, but I changed the word generations. It too much a marketing term and it does not describe that there are three types of distinct configuration to mesh radio node. I believe this concept is a marketing term from deCosta's company. I see that there is no real "generation" upgrade until we see the IEEE standard on wireless mesh. A distinct innovation or upgrade to wireless mesh has not happened. I hope this clarifies the change to the word. Thanks DAM PS I know there will disagreement with this change but I believe the words I choose simply better the describe deCosta excellent description. Thanks again. —Preceding unsigned comment added by 206.186.167.6 (talk) 21:52, 14 December 2007 (UTC)

They're not encyclopedic. Index pages for commercial sites aren't what we're looking for in references. I've improved the ref syntax anyways, but these should be refined. E_dog95' ^{Hi '} 07:44, 24 February 2008 (UTC)

Redundant Mesh Networks

A Redundant Mesh Network is a Mesh Network in which each node has more than one node connected to it. This supports data path redundancy that allows the first packet (or packet stream) received by a node to "lock out" identical packets (or the same packet stream) that attempt to enter by another connected node. For example, in an audio/video player or codec application, the first packet received by a node can be transmitted on, while subsequent packets containing the same information (destination and data) are dropped. This minimizes transit time across the network, which is useful for such an application by making it less likely that video frame updates will be lost. An example of a codec using an algorithm similar to this is Octoshape, which appears to drop fewer video frames than other video codecs.

Note: Since the above information is new and not yet verifiable, I have put it here instead of adding it to the article. After review and correction by an expert, and the addition of references, it can be moved to the article. David (talk) 19:52, 25 April 2009 (UTC)

Ref to Sensor Networks

Example of a wired mesh network --> sensor network. Sensors have been laid out in meshes for long time. I am not an expert on sensor networks, but this article needs to mention sensor networks (especially WSN). Ooskapenaar (talk) 08:00, 25 January 2010 (UTC)

A list?

The product Daihinia for example is not mentioned but putting "wifi mesh relay" into Google finds it. I'm curious as to how many projects (both commercial and nonprofit) have an off the shelf implementation. And no, I don't want to make a page full of links. JWhiteheadcc (talk) 11:28, 7 October 2010 (UTC)

Precise definition

I am wondering if the wikipedia-definition of meshed-network is a precise definition: "Mesh networking (topology) is a type of networking where each node must not only capture and disseminate its own data, but also serve as a relay for other nodes, that is, it must collaborate to propagate the data in the network."

If every node must relay for other nodes, then there can't be any node who is on the "edge" of the network. By talking in the words of graph theory, this would mean that there are no vertices with an degree of 1. Why do I think this? -> Because a node who has only one neighbor has no reason to relay any information (he only transmits the information which it is the source or the destination of).

So if we look at the picture which shows an example of a meshed-network: This would not be a mesh network, because there is one vertex which is only connected to one neighbor.

Meshed network also seems to me as a network where the nodes are connected to a lot of others. But this would be no precise definition. Does the definition of meshed network only depend on the topology? Is it a precise term or something people could disagree about in some cases?

Thank you for every explanation! Zeus37 (talk) 11:21, 12 December 2012 (UTC)

I would propose the following change to the definition:

Mesh networking is a style of networking that depends on the lowest level nodes (i.e., the edge nodes or the leaf nodes) forwarding data for other lowest level nodes. The mesh network is normally non-hierarchal, but may be embedded in a larger hierarchical infrastructure such as The Internet.

Kenneth At Samraksh (talk) 21:07, 7 May 2013 (UTC)

Fully Connected is not Mesh

A fully connected network cannot be a mesh network. In a fully connected network nodes do not, or at least should not, rely on other nodes to forward their messages.

Flooding technique?

In the current revision, the beginning of the second paragraph states that "Mesh networks can relay messages using either a flooding technique or a routing technique." Then the paragraph continues to explain the routing technique but the flooding technique is left in the dark. I suppose "flooding technique" refers to Flooding (computer networking), so as a temporary solution I've added a reference to that page. By the way, in "... either a flooding technique or a routing technique.", can't the first instance of "technique" be left out? Th0rgall (talk) 10:29, 21 February 2016 (UTC)

Mesh Network using Current Cell Phones

Regarding Independent Private Networks for Residences And Offices Using a Combined Mesh Topology of Media Servers and P2P File Sharing

This article has very little support for / linkage to the popular culture concept or the alternative concept of building private networks from scratch. The underlying question is how you would once again set up the internet for colonies on mars or on the moon, this question is common in modern worldbuilding or citybuilding experiments. Meshnets are a term that frequently pop in as a solution to this. Essentially, it is not wrong to use the phraseology "internets" while describing unfederated private networks, which need not be against cyberlaws or in need be associated with any of the negative aspects typical to privatized file copying over networks. The research on content bubbles should at some point focus on distinguishing meshnets against more typical internet setup over ISP; whichever is more liberating in terms of utility. It would be nice if this article could be updated to reflect notice to the aspiring DIY focusing on rebuilding global connectivity.
