ICT – high bandwith wireless ad-hoc multihop mesh: perspective of widespread mesh

I have been interacting with http://reseaucitoyen.be∞; / http://reseaucitoyen.be/index.php?ReseauCitoyen∞;
I think that the perspective of video-streaming trough local ( including mobile ) ad-hoc mesh networks is potentially a very interesting one. http://reseaucitoyen.be/index.php?MeshNetwork∞; / http://reseaucitoyen.be/index.php?ProtocolesDeRoutagePourReseauMobileSansFilAdHoc∞;

Theoretically, current popular consumer digital wireless devices can exchange information at speeds of about 10 MBits/s for the 802.11b and up to 54 MBits/s for some other current standards.

What I understand out of alot of the experiences and knowledge building done in relation to - open - mouvements such as ReseauCitoyen is that, practically, there are all kind of parameters that interfere on such kind of performances.

Nevertheless, I like to dream of a possible future where production costs of wireless devices will be cut to a fraction, and eventually be integrated to most chips/processors ( in pc's such as can already be the case, but also more and more in all kinds of devices that do use a chip such as our tv's, fridges, electronic devices in cars, and offcourse, mobilephones )

This vision has already been somewhat widely advocated. What I would like to see as an extension of such a vision is that all these chips with wireless communicating capabilities would contain some source code making it capable to do ad-hoc multi-hop transfers of data. http://reseaucitoyen.be/index.php?MeshNetwork∞; / http://reseaucitoyen.be/index.php?Mesh∞;

Ad-hoc Multi-Hop data transfer is a field in wich the reseaucitoyen mouvement already works on, and tries to apply to a few nodes-routers ( relay server with antenna ) they are installing in cities and that have a range of a few hundred metres, and sometimes more ( the record of some individuals interacting with the mouvement is a poorly performing data exchange with a range of about 13 km from a tower in a countryside - open vision environment )

Setting the kind of routers they work with demands some technical expertise ( that not everyone is willing to acquire ) and some investment in ressources. ( they often recycle old computers, or use hardware packages such as http://reseaucitoyen.be/index.php?PrototypeDeLaMachineIdeale∞; )


If this could be brought further, and if all chips could become routers, since the density of electronic devices within cities is very high, one could imagine that on a local scale data could be transferred freely with a highbandwith capability trough this mesh with a minimum, or even, with no supplementary investment in hardware.

Every device ( any mobile phone, television, wifi card, car radio, ... ) would be able to relay the data to another device within a range of a few metres, or eventually more depending on factors such as environment and transmission power - in watt's -

Because there could be such a density of relay devices , pathways would be numerous, and the risk of bottlenecks might be reduced.

I imagine that to make the system even more efficient certain long range well positionned powerfull routers+efficient antenna could be placed strategically

Bandwith could be high, but speed is also an important factor. Data would be transferred at the speed of light between every node, but at every node-router it seems that a hop currently takes, if I remember properly, something like 0.002 seconds. The software is supposed to be designed to allow information to take the most efficient route. Placing longer range routers can be usefull.

It would still be much faster and cheaper then data transfers going trough non-optic cables.

There are many other aspects that probably would have to be solved.

Futher enhancment of the related software code is a important aspect.

But one of the major hurdles I see to such a vision is one related to convincing producers and consumers to design and use the harware with software that allows for every user to be a bridge to someone elses information for free.

Maybe it might be possible to imagine that such an option would be available within the device itself to the consumer/individual using-possessing it, and that he might decide to switch on or off the ad-hoc multi-hop capability and sharing.

But the benefits of sharing might be so big that I think there are good arguments and interests in people sharing.
And even if only a small portion of people allow their device to become a transfer router-node, it would potentially already create a huge mesh network at minimal cost.

I imagine that probably players such as mobile telephone companies might not be very happy about such developments, since one of the possible applications would be that two users within a city - and/or behond when linked to the internet (See SharingConnection - Internet Sharing ) - can exchange information ( including voice ) for free between their mobile phones/multimedia devices , and that there possibly might result into political pressures on goverments to reduce the freedom of individuals to use, for example, available radio frequencies legally, or non-commercially. ( for example, if the state further sell's the currently public domain radio-frequencies, or the radio-frequencies that are optimal for high bandwith data-transfer. ) ( xxx recently , I remember frequencies such as around the 2.4 Ghz on wich 802.11b operate have been made legally for use by the public domain. One could imagine that certain goverments might be tempted to sell 5.4Ghz frequencies, on wich higher bandwith standards such as 802.11a operate, to the private sector. )

I m sending this also to the ReseauCitoyen MailingList incase anyone would want to react on this ( see http://tech.groups.yahoo.com/group/socialagriculture/ ; first message on this topic:

http://tech.groups.yahoo.com/group/socialagriculture/message/193 ) :

Suggestions for the development of Wireless Internet Connectivity - for the project in Kenya , with examples of other projects in other places in europe and africa ( bombolong ) ; development of standards? ( Wi-Mesh proposal for IEEE 802.11s ? ) ; Geek Corps - http://www.geekcorps.org/ , etc :

To begin with , maybe check out Geek Corps:



Using AODV - Ad-Hoc On Demand Disance Vector Routing Protocol



and/or Oslr -

Optimized Link State Routing (OLSR) protocol


antennas can be home made - see:



I dream of having such wireless routing protocols integrated and operational in Mobile phones , and also have people install them on their wifi enabled laptops , and in any electronic device that has a processor ( televisions? radios? , etc - also CB s of Truckers? )

this would instantaneously open up access to networks almost everywhere , at a very very low cost , and also in developing countries.

PS: the one laptop per child / 100 dollar laptop also includes ad hoc multi hop wireless capability:




also see


extract: " One networking solution for the $100 laptop, operating at the Internet address level (or Layer 3), is the ad-hoc routing protocol AODV. "

also see:

Wi-Mesh proposal for IEEE 802.11s


and for more on these perspectives , see my old brainstorming ( 2004-07 )


Some people I know from Brussels , that have also been involved in the development of a open ad hoc multi hop wireless network in Brussels
( see: http://reseaucitoyen.be ; on google: http://www.google.lv/search?q=reseaucitoyen&ie=utf-8&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a )

have been setting up a NGO aiming at developping wireless ad hoc multi hop network solution projects in african countries ( AODV : Ad-Hoc On Demand Distance Vector Routing Protocol )







( non governmental organization )


ps: for translation:


you might be able to contact people related to bombolong on the Niouz reseaucitoyen mailinglist , or on
bombolong - at - reseaucitoyen.be

and although he might be busy ,

One of the central people in reseauCitoyen , Bombolong , and Hellea , is Jean-Charles.

Dear Gary,

Our Minciu Sodas lab is working with our researcher Samwel Kongere in Rusinga
Island, Kenya. He is leading one of our team's for Greg Wolff's MyFoodStory

We have at least $500 to spend to try to set up wireless Internet access for
him. Perhaps we can organize more. What do you advise, what is the best way
to spend such money?

Business model and emergence of metatized network / ad hoc multi hop (wireless) networking on short and long distances , using all electronic ( mobile ) devices capable of receiving and transmitting signals.

The idea is to create emergence of any such devices that could in effect be relays for other signals ,
by including to these devices a software that allows ad hoc multi hop networking :



The business model is to offer companies to install such as hoc routing protocol softwares in all the devices available ( computers , mobile phones of employees , laptops , ... )

as to increase the communication bandwidth between all computers.

This might be especially interesting for specific industries that demand a lot of bandwidth within their offices.

It could also be a experimental ground and a starting point for expanding the use of ad hoc mobile protocols in all laptops and mobile phones ( with the options for users to switch it on or off )

By emergence , this opens up bandwidth communication for data transfer ( including voice for ip phone calls ) in all areas that have a high density of such devices.

As smaller less powerful devices would only be transmitting on a short distance , other ( cheap ) longer distance relays could reduce the number of hops , and eventually also connect those ad hoc networks to the internet.

If it grows enough , such a ad hoc network could become an alternative to the internet , and avoid control over the internet.

It is also a cheap option to provide free bandwidth communication , especially in cities

also se my older brainstorming on :


ad hoc routing : part 2 - CB s becoming IP phones and routers - opening up digital bandwidth by combining a digital adaptor with CB s

note: also see


already today , on major roads of the developed and developing worlds , trucks ( and cars ) are equipped of ( old and newer )

CB 's

see :


These do not emit digital signals , although one could imagine to develop a small adapter that would make it possible to use specific frequencies of the CB to send and relay digital signals over the CB

It would be interesting to see how much it would cost to adapt CB s , and to ( mass produce ) a small adapter that could be connected to the CB so tha the CB can still be used for its initial use , but also be used to send , receive , and relay digital signals on standard CB frequencies , that other CB s can relay if equipped with such adaptor.

This would make it possible for CB s to transmit greater amounts of data , and communicate on much greater distances and can connect directly with the desired recipient through IP , transforming CB s into mobile IP phones and relays , or even internationally if the relayed signal reached a relay connected to the internet.

It can also be a cheap solution for opening up communication infrastructure in areas that do not have developed communication infrastructure , and/or to open up such bandwidth FOR FREE to the populations and users , and also to open up bandwith relay channels between populated areas along its transportation network / roads , even along less developed roads infrastructures and regions

another interesting option is to integrate ad hoc routing capability in hand powered digital radios such as



and also make it possible for such radios not only to become relays , but transmitters and receivers , transforming them also in IP phones.

they could become part of the ad hoc mobile network of relays mentioned in my last two mails ,

and could also be relays for wifi signals , or transforn wifi signals into other frequencies as to relay these initial wifi frequencies.

100 dollar laptops


will have ad hoc relay capacity , and we could imagine they could also be receivers of DAB signals :


and eventually also

DVB signals


or relay digital signals other then the ones in the wifi spectrums ...

all devices would become relays for signals of other devices , and could also receive and transmit.

Wind up digital radios and 100 dollar laptops would also become IP phones... and at the same time , would be part of the mesh opening up the bandwidth capacity...
