Weligaa ma ka fikirtay waxaad samayn lahayd haddii aad si lama filaan ah ugu xidhi waydo intarneedka^{(couldn’t connect to the internet)} si aad dadka kale ula xidhiidho, ama aad hawl maalmeedkaaga u qabato?

Inteena badan waxaan u nimid inaan ku tiirsanaano internetka waxyaabo badan sababtoo ah adeegsigiisa badan. Markaa, wax kasta oo ka hor istaaga gelitaanka shabakadda iyo adeegyada kale ee khadka waxay ka dhigayaan waxyaabo ay ka mid yihiin wadaagga faylalka, wax iibsiga, warbaahinta qulqulka ah iyo kuwa kale ku dhawaad ​​aan suurtagal ahayn in la sameeyo.

Farriinta mesh in kastoo, waxaa suurtagal ah in lala xiriiro kuwa kale iyada oo aan la helin shabakad la maareeyo oo joogto ah oo aad isku xirto midba midka kale.

Maqaalkan, waxaan kugu caawin doonaa inaad fahanto waxa fariimaha mesh yahay, sida loo isticmaalo maanta oo aan sharaxno sida ay u shaqeyso. Haddii aad jeclaan lahayd inaad wax badan u sii dhex gasho noocyada kala duwan ee shabakadaha, waxaanu kugula talinaynaa inaad siiso hagahayaga shabakadaha kombayutarka^{(computer networks)} akhris.

Waa maxay Farriinta Mesh?

Farriinta mesh^(Mesh) -ka ama fariimaha ka-baxsan waa nidaamka isku xidhka faca-ilaa-fac kaas oo u oggolaanaya isticmaalayaasha inay midba midka kale la xiriiraan iyaga oo aan ku tiirsanayn unugga ama shabakadaha WiFi , ama kaabayaasha kale ee ay dawladdu maamusho.

Tusaalaha wanaagsan ee meesha fariimaha mesh-ka ah loo adeegsaday waa mudaaharaadyada Hong Kong ee 2019. Boqolaal kun oo rayid ah ayaa buux dhaafiyay waddooyinka waxayna qabteen mudaaharaadyo ka dhan ah dambiilayaasha baxsadka ah ee wax ka beddelka sharciga^{(anti-extradition demonstrations against the Fugitive Offenders Amendment bill)} kaas oo u oggolaanaya dowladda in ay dib ugu celiso dambiilayaasha looga shakisan yahay Shiinaha^(China) . .

Mudaaharaadyadu waxay socdeen toddobaadyo, taasoo ku kaliftay bilayska inay adeegsadaan habab rabshado wata si ay u joojiyaan dadaallada. Sidaa darteed, mudaaharaadayaashu waxay u baahdeen hab ay ku wada xiriiraan midba midka kale iyada oo aan ku xirnayn isku xirka internetka, si ay isu abaabulaan oo ay u badbaadaan.

Si arrintan loo sameeyo, waxay isticmaaleen barnaamijyada casriga ah ee ka baxsan sida FireChat iyo Bridgefy , kuwaas oo ka shaqeeya abuurista shabakado iyaga u gaar ah oo ka baxsan internetka iyo qalabka gacanta. Waxay inta badan ku tiirsan yihiin isku xirka WiFi ama Bluetooth ee ka dhex jira laba ama in ka badan.

Labada barnaamijba waxa ay ka diwaan galiyeen kumanaan la soo dejiyay gudaha Hong Kong oo kali ah intii ay socdeen mudaaharaadyada sababtoo ah waxaa jiray dad badan oo ku sugnaa aagagga mudaaharaadku, taas oo ka dhigtay gabi ahaanba shabakada gacanta inay gaabis noqoto.  

Qaar ka mid ah isticmaalka ugu habboon ee fariimaha mesh-ka waxaa ka mid ah:

• Inta lagu jiro masiibooyinka sida dhulgariir, daadad, duufaanno, iyo dab iyo kuwo kale
• Socodka kaynta ama koox koox kaamaynta^(Jungle) meelaha fogfog iyada oo aan la soo dhawaynayn
• Aagga dagaalka ama marka ay socdaan mudaaharaadyo waaweyn oo ay dowladdu u badan tahay inay xirto internetka
• Marka aanad haysan xogta mobaylka ee telefoonkaaga ama qorshahaagu dhacay
• Markaad safrayso oo aanad ag fadhiisan qoyskaaga ama asxaabtaada isla gaadhi ama diyaarad

Sida Fariintu Mesh u shaqeyso^{(How Mesh Messaging Works)}

Farriinta mesh^(Mesh) waxa ay ku soo dirtaa xogta Bluetooth ama ad hoc WiFi oo la mid ah waxa talefankaagu dejiyo marka aad isku dayayso in aad hesho kamarad amniga guriga ama aaladda smart online.

Nidaamku waxa uu u qaabaysan yahay si aanay cidina ula socon ama u xakamayn karin wada sheekaysiga aad ku socoto. Sidan, tuugada ama maamulka ilaalada dawladu midkoodna ma soo gali karo munaaradaha gacanta si ay u xidhaan kanaalada isgaadhsiinta, u jiidaan mareegaha aad isku dayayso inaad dadka kale kula xidhiidho, ama xataa dhegaysato wax kasta oo lagu soo bandhigay adeeg bixiyahaaga internetka.

Abka^(Apps) loo isticmaalo fariimaha mesh uma baahna shabakadaha internetka ee caadiga ah. Intaa waxaa dheer, waxay u sameeyaan xiriir ka dhexeeya isticmaalayaasha si la mid ah habka qulqulka software-ku sameeyo, halkii ay ka nuugi lahaayeen faylasha kaydka dhexe.

Haddii aad haysato app farimo mesh ah oo lagu rakibay taleefankaaga casriga ah, dad badan oo kale oo isku meel ahina ay haystaan ​​app isku mid ah, way fududahay in la isu gudbiyo fariimaha midba midka kale si ay kooxda relay-gu ugu gudbiso usha. Si kastaba ha ahaatee, gudbintu waa mid aan la arki karin qof kasta oo fariinta u diraya dadka kale si aanay u akhriyin dadka kale marka ay sii socoto.

Mabda'a ugu muhiimsan ee shaqada ee fariimaha mesh waa isgaarsiinta qalabka-labka. Tani waxay ka dhigaysaa isticmaalka isku xirka Bluetooth^(Bluetooth) -ga gaaban si loo sameeyo shabakad oo loo dhaafo unugga ama shabakadaha WiFi^{(bypass cell or WiFi networks)} , iyo kaabayaal kasta oo kale oo ay dawladdu maamusho.

Ujeedada ugu weyn ee fariimaha mesh-ku maaha in laga ilaaliyo raadaarka dawladda, laakiin waa in la suurtogeliyo isgaadhsiinta meelaha xidhiidhkoodu liito, ama meelaha fogfog ee aan lahayn qaab xidhiidhsan. Waxa kale oo ay imanaysaa xilliyada dhacdooyinka garoommada halkaas oo taageereyaal badani ay is dhexgalaan, ama meelaha ay aafeeyeen masiibooyinka dabiiciga ah sida dhulgariirrada iyo daadadka, kuwaas oo burburiya taawarrada gacanta iyo shabakadaha WiFi .

Mesh messaging apps waxay isticmaalaan shabakada mesh si ay ugu xidhaan aaladaha isticmaalaha iyagoo isticmaalaya Bluetooth , taasoo u ogolaanaysa fariinta inay ka guurto hal qalab una guurto mid kale ilaa ay ka soo degto sanduuqa qofka loogu talagalay.

Mar haddii talefoonka Bluetooth-ka iyo kala duwanaanshaha taleefoonka uu caadi ahaan kor u dhaafo 100 mitir, waxaa suurtagal ah in lala xiriiro dadka kale inta u dhaxaysa ilaa 200 mitir. Way waxtar badan tahay marka laba ama in ka badan oo taleefan ah ay isu jiraan, haddii kale xoogga ishaarada ayaa saameynaysa.

Masaafada dheer, in kastoo, fariintaadu waxay ka dhex boodi doontaa isticmaalaha kuugu dhow waxayna abuurtaa shabakad mesh ilaa ay ka gaadho qofka loogu talagalay. Tusaale ahaan, talefanka A si toos ah uguma xidhi karo talefanka C, mesh meshing app waxa uu fariinta ka soo boodayaa A ilaa C talefoonka B.

Waxaa dheer, dadka soo gudbinaya fariinta uma baahna inay ku jiraan liiska xiriirada ama sameeyaan ficilo kale si kasta ha ahaatee si ay u gaarto bartilmaameedka aad damacsan tahay. Tani waxay adkeyneysaa in dowladda ama hackers-ka ay xiraan maadaama aysan jirin hal qodob oo fashil ah oo la beegsan karo in la xiro.

Isticmaalayaasha badan ee shabakada mesh, waxa fiican in la diro fariimaha mesh.

What Is Mesh Messaging & How Does It Work?

Have you ever thought about what you’d do if suddenly you couldn’t connect to the internet to communicate with others, or get your everyday tasks done?

Most of us have come to rely on the internet for many things because of its many uses. Thus, anything that hinders access to the web and other online services would render things like file sharing, shopping, streaming media and others almost impossible to do.

With mesh messaging though, it’s possible to communicate with others without a persistent managed network and stay connected to each other.

In this article, we’ll be helping you get a grasp of what mesh messaging is, how it’s being used today and explain how it works. If you’d like to delve more into different types of networks, we recommend you give our guide on computer networks a read.

What Is Mesh Messaging?

Mesh messaging or off-the-grid messaging is a peer-to-peer networking system that allows users to contact each other without relying on the cell or WiFi networks, or any other government-controlled infrastructure.

A good example of where mesh messaging has been used is in the Hong Kong protests of 2019. Hundreds of thousands of civilians filled the streets and held anti-extradition demonstrations against the Fugitive Offenders Amendment bill that would allow the government to repatriate suspected criminals to China.

The protests went on for weeks, prompting police to use violent and aggressive means to quash the efforts. Consequently, the protestors needed a way of communicating with one another without depending on an internet connection, so as to organize themselves and stay safe.

To do this, they used off-the-grid smartphone apps like FireChat and Bridgefy, which work by creating their own networks outside the internet and carrier cell masts. They rely mainly on the WiFi link or Bluetooth that exist between two or more phones.

Both apps registered thousands of downloads in Hong Kong alone during the protests because there were lots of people in the protest areas, which made the cell network slow altogether.  

Some of the ideal uses of mesh messaging include:

• During disasters like earthquakes, floods, hurricanes, and fires among others
• Jungle trekking or group camping in remote areas without reception
• In a war zone or during mass protests where the government is likely to shut down the internet
• When you don’t have mobile data on your phone or your plan expired
• When traveling and you’re not seated next to your family or friends in the same vehicle or plane

How Mesh Messaging Works

Mesh messaging sends data via Bluetooth or ad hoc WiFi similar to what your phone sets up when trying to get a home security camera or smart device online.

The system is structured in such a way that no one can monitor or control the conversations you’ve got going. This way, neither hackers nor government surveillance authorities can tap into cell towers to block the communication channels, pull down websites you’re trying to use to communicate with others, or even listen in on whatever is being beamed to your internet service provider.

Apps used for mesh messaging don’t need traditional online networks.  Plus, they make connections between users in the same way torrenting software does, instead of sucking files from a central repository.

If you have a mesh messaging app installed on your smartphone, and many other people in the same area have the same app, it’s easier to pass on messages to each other the way a relay team would pass on a baton. However, the passing on is invisible to everyone sending the message to others so it’s not being read by other people as it moves along.

The main principle at work in mesh messaging is device-to-device communication. This makes use of short-range Bluetooth connections to form a network and bypass cell or WiFi networks, and any other government-controlled infrastructure.

The main purpose for mesh messaging isn’t necessarily to keep off the government radar, but to enable communication in areas with poor connectivity, or remote locations with no form of connectivity. It also comes handy during events in stadiums where many fans would interact with each other, or in places that have been ravaged by natural disasters like earthquakes and floods, which destroy cell towers and WiFi networks.

Mesh messaging apps use the mesh network to link users’ devices together via Bluetooth, allowing the message to move from one device to another until it lands on the intended person’s inbox.

Since Bluetooth’s phone to phone range typically maxes out at around 100 meters, it’s possible to communicate with other people within a range of up to 200 meters. It’s more effective when two or more phones are within range of each other, otherwise the signal strength is affected.

For longer distances though, your message will jump between the nearest user and creates a mesh network until it reaches the intended person. For example, phone A can’t connect directly to phone C, the mesh messaging app will bounce the message from A to C via phone B.

Plus, the people forwarding the message needn’t be in your contacts list or perform any further actions whatsoever for it to reach your intended target. This makes it harder for the government or hackers to shut it down as there’s no single point of failure that can be targeted to shut it down.

The more users in a mesh network, the better mesh messaging works.

How to Use A Mesh Messaging App

For you to understand just how mesh messaging works, we tested one of the popular off-the-grid apps, Bridgefy, and here’s a step-by-step guide on how to use it.

• The first step is to go to Google Play Store or App Store depending on your phone, and download the Bridgefy app. For this guide, we’re using an Android smartphone with Android 9 version, so we’ll download the app from Google Play Store. 
• You’ll find two apps listed under Bridgefy: Bridgefy-Offline Messaging and Bridgefy Alerts. Download the Bridgefy-Offline Messaging option.

• Next, launch the app and set it up by tapping Get Started on the new screen. 

• Complete the set up by adding a username (preferably one your contacts know you by) and tap Complete setup.

• Click Next in the new screen and give permissions for the app to access your Location settings to use Bluetooth communications, and your Contacts list.

• If you get a popup that requests you to update Location settings, tap Enable, and move the Location slider to On. Hit the return button on your phone to go back to Bridgefy.

• You’re now ready to use Bridgefy for mesh messaging. In the Chats screen, you’ll find two red buttons: Spread the love and Add a friend. You can use them to invite friends to join you on Bridgefy or add a friend to your list who probably already uses the app. 

• If you tap on Contacts, you can see the people on your Contacts list who are already using Bridgefy. There’s also a Share button you can use to invite those who aren’t using the app yet.
  
  Next to each contact, you can see who is nearby that you can get in touch with. A red bubble with the words In Range will show besides each contact who is closer to your current location. 

• Tap on a user’s name to start sending them messages. You can also send your location by tapping the red button at the lower right side of the screen.

• Tap the pin and then tap Share My Current Location (works with Google Maps).

• Bridgefy also sends you notification pop-ups whenever you receive a new message, just as you’d get with apps like WhatsApp and other messaging apps.

Note: During testing, we moved around the building with our phones and tried sending messages from different rooms. We discovered that we couldn’t communicate as our messages would either show a little timer icon indicating the message is pending delivery, or Retry (with an exclamation mark) indicating they’ve not been delivered or they failed to send. 

As we came closer within range, the messages started trickling in one after another. All messages that were sent and delivered show the green double ticks akin to the blue ticks on WhatsApp.

Make Messaging Easier

Mesh messaging is a great way of protecting your privacy while avoiding surveillance by the government or online snoops. It won’t replace your day-to-day communication, but it definitely makes messaging at busy places easier, and offers safe way of communicating and coping if the internet can no longer be used or trusted.
