[Q] DTN stack on Android platform? - Android Software Development

Hi all,
Does anybody know whether Delay Tolerant Networking (DTN) protocol has been added to Android's mobile stack or not ? Any references or links would be great if you're aware of a group, webpage, code repository etc.
Thanks in advance,
Roger

Nobody?any ideas?

I suspect that few people on these forums are aware of what DTN actually is.
I was just wondering this myself, and google turned up this post. It appears that there was some work done on it (http://www.theregister.co.uk/2009/11/05/vint_cerf_on_mobile/) a few years ago.
The official site (http://bytewalla.sourceforge.net/) includes source code and an apk file to install it, though it's light on the details.
I plan on trying this out myself over the weekend.

I've managed to compile cryptophone for PocketPC 2003

I've build a version of crypto phone for PocketPC 2003. ( unsing the sources from www.cryptophone.de ),
with some workarrounds for license test.
I don't have two phone to test it yet. If anyone can test it please send feedback.
As i see it use data call as link layer so your provider must suport it.
PS: Who's testing it , please send feedback.
I've tested in my Qtek 2020, (XDA II, MDA II…).
Is it working? I was able to compile it too, but it died on exchanging keys.

Don't work. :-(
I have programmed 2 xda 1 with wm2003 and the crypto, it works perfectly. The only bug is the "file" bar vanishes after a call is placed or received, other than that its great. 8)
Can you post what you changed in the source file in order we could reply your compiled code?
The idea is simple, if we can have access to the original source code and can do the changes you documented, generating the same code as you, with the same hash value for the encrypted code, we can assure that your code have the same security of cryptophone.
dumb ?
what is cryptophone?
Hi,
i am very interested in this (or a similar) software for
the Wallaby or Himalaya platform.
Anyone here who has a working & easy too install binary?
(Or are there any real free & opensource applications like cryptophone?).
kind regards,
Ben
Has anyone managed to get cryptophone working on the XDA ??
... or find a similar program ??
Regards
There are several similar commercial projects. Just wait some time for their announcements.

2-3 russian companies are also working on similar projects. I don't know their sites.
cryptophone Somebody to compiled? for motorola smartphone mpx220 :?
one more company.
http://www.securegsm.com
and question - where is source download page on http://www.cryptophone.de ?
in general "cryptophone" application isn't difficult
- good vocoder
- some crypto
- good realtime data transfer - CSD for GSM network
- some audio components like AEC
could some one point me to good ARM implementation of vocoder with 2.4-4.8kbitps bitrate? ARM9(v5) PXAxxx ~100MIPS.
Free is preferable, but reasonable commertial offers are welcome too.
just a question,
isn`t it possible with the sourcecode of this software and the sdk for windows mobile 2003 smartphones to make a installer?
is very interesting, or?
is there any other software for ppc or smartphone avalable?
a free wm5 client for this should be awesome! coders go compile now!
is the encryption limited to "only" this version of application ?
- or is there some sort of standard ?

Hi, did you manage to get it to work?
I tried on my O2 xda... it hung on the key exchange part...
It concerns me that this program starts two processs, spcore.exe and ui2003.exe. I have not looked over the code, but can you tell me why it must use two. Furthermore once they are going there is no way to stop the spcore.exe. My guess is that if that process contains the thread that is waiting for tapi events, its stopping mechanism has not been implemented properly. If you want to make a thread that is waiting for the event for line state then when the user wants to stop the thread/process, the event interest needs to be reset. eg SetCommMask(hSerialHandle,0); ,but it must be done from the ui thread not the waiting thread because obviously the waiting thread cant do anything. Once it is set to 0 (as apposed to EV_RXCHAR for example) the waiting thread will finish waiting imeadiately.
I tried sending a message to destroy the window with no effect, I then tried using terminatethread to stop it but that did not work so it must be in an api call (such as waiting).
On my mini it starts up ok, and dose not interfear with the phone. I could not test the functionality because the only other phone I had with me was my xda and it dose not install corectly on that. No error messages on intalation but the icon in the program files is not shown properly and it fails when I try to start it.

TyTN cellid?

Hi. I am writing a freeware social networking application based on location services ( http://www.fightersoft.ro/mts/index.htm ). Although many devices are supported, it seems that the HTC TyTN isn't. To that end I acquired one and now I am on the quest on getting the cellid in my application.
The approach that should of worked was the COM port. However, no matter what COM port I open, I get a create file error. I am guessing that maybe the internal modem uses a weird port name such as COM550 or other letters instead of COM. I know that another way of getting the cellid is by using ril.dll (or even getting the handle to the gsm modem com port). However, in WM5 this is not documented at all on msdn.com - BUT for WM6 there is documentation.
Firstly, I want to ask anyone if they have extra information about this issue and secondly if by upgrading to WM6, the using the COM port approach works from the box (usually COM9)?
hi, I tryed many programs, which have actually support for cellid information, but no one work on herm, no matter if it was WM5 or WM6. on all phones, I had before it worked correctly... phone alarm also have this functionality, but shown only something like 00-00...
This is so frustrating. Every mobile device with GSM capabilities has a GSM modem insinde. That modem SHOULD be accesible from the OS by the means of COM ports. My guess is that this port is hidden or under a different name than the rest of the HTC devices where it resides on COM9.

I started this thread in the hopes that people will contribute with ideas towards getting this task done. Can you reveal any technical information on how you get the cellid information?

Sure. Ril.dll gives you access to this information and works properly in WM5-WM6. And technically is easier than manager serial drivers......
Documentation isnt included in WM5 so it isnt "official" but realky It is included. The only problem for "not official" issue is you wont get support from microsoft....
Ask me what you want...
stargatesg1, if you have searched the forum, you'd already have the answer. For instance, this thread:
http://forum.xda-developers.com/showthread.php?t=280476&highlight=cellid
has a reference to RIL API. And I do remember I told you this some months ago in your another thread...
Here it is:
http://forum.xda-developers.com/showpost.php?p=1040464&postcount=27
It was at October 26 last year!
Basically I only need the cellid and the lac. I found that msdn.com offers documentation for ril.dll for WM6. This also works for WM5?
From what I learned from msdn.com is that I should do a ril.initialize first and then I should get the cell info using a fuction that I can't remember right now. Is this approach correct?
Lurker0, I know about this approach (I have mentioned it in my first post) however, I need more information because c++ native is not my primary envoirement for developing. That's why I kept searching for a way of getting the lac-cid from com ports so that I could do it directly from managed code.

Exactly. I downloaded Platform builder to have includes and libraries.
1) Initialize Ril
2.a) Request Position explicitally using a RIL_gettowerinfo
2.b) When you initializa Ril you can pass a callback to be notified upon location changes....
Did you read the source code for RIL interface that I pointed you to?
danielherrero, I see. Regarding the callback function is not neccessary in my app - the user or the app set on auto mode searches for changes in location. Thank you very much for your info.
Lurker0, yes I did, but like I said, I am not a very experienced c++ programmer and I need some documentation to get me started. I am also very greatful for your help and I am sure that I will use information from rilclass.cpp.
Thank you both, I will post back with the results as soon as I will have any.
Good luck
Hi StargateSG,
Did you succeeded in getting MTS working on Tytn?
Rgds
I had to leave the country on a business trip. I'll get back in a few days and I will start working on the problem.

Collaboration tool/ networking

Hello,
I have a few people in my group and I would like to collaborate with them better then what we do now: email, etc. I was wondering if anyone has yet developed a multi-platform collaboration that can be as easily accessed from the web as from the phone? I'm sure someone has already done this? I'm trying to create a horizontal type information sharing for a site www.edward-palonek.com. There are several people who write and post information but most of them are pretty mobile. I was thinking about something like a wiki, but web access to a wiki from a mobile phone can be difficult, any ideas?
Thanks
*bump*, any ideas?

3G-324M

As most of you know, 3G-324M is the 3GPP umbrella protocol for video telephony.
I am thinking on start building a protocol stack to develop VT Apps.
Does anybody have info on this?
Is, by any chance, somebody interested in starting this project with me?
Thanks
Wouldn't be that easy...
Hi there,
I've developed a 3G-324M stack in the past from the ground up. And I must say that 3G-324M is quite complex, and there's no easy way around it, there's a reason why there is no open source solution for it yet.
As it is, XDA based handsets already have the protocol embedded in them as part of the phone, so the issue is either controlling the application on the phone itself or building a server.
You can read more on 3G-324M on my blog by following its tag: http://blog.radvision.com/voipsurvivor/tag/3g-324m/

That's why you could help us developing this protocol stack.
What I have in mind is a way to simplify who wants to develop mobile applications 3G enabled.
(I know that RADVISION has a toolkit with this protocol stack implemented and ready to use but it is comercial and not available to everyone)

kindly suggest give some more info ...thank u in advance..........
i hope this can help
hi all,
I was surfing on net and i got this manual i hope this will help u in some wot understanding.
http://www.nmscommunications.com/swDocs/Docs/62471-13.pdf
please reply if u are able to develop it as i am using samsung infuse 4g and dying to use native video calling.
As far as i understand this 3g 324m protocol will be intergrated in touchwiz 4.0 and that why it is possible in samsung galaxy s and s2.
I hope I can help
Hi ATHelp,
Have you started off with this project?
I am interested in building the 3G-324M protocol stack.
Let me know if we can get this started (if its not already started)..

Looking for Developers for Public Online Application Libary

Greetings all,
I'll cut right to the chase. I'm looking for a enthusiastic developer to help me develop an application for a 'iPhone' style app store.
I have some rough ideas on how to go about this, but im not completely in touch with the development of Windows Mobile Based applications.
The application will essentially connect to a hosted website of mine containing free / opensource / demo WM6 applications with the option to download and install to your phone.
I've thought of using a RSS style backbone for the application as i think it would be the easiest way to go about receiving updates from the website with links to .cab 's for download.
I'm aiming for this to be a free hosting service for aspiring developers to get their applications out there and easily accessable for others on their WM6 devices
The only thing i can really offer in return is credit on my application hosting page for the client software, and a agreed percentage of any revenue i may or may not receive in the future.
I am aware of the proposed one by MS but they are asking $99 for devs to post their applications on there, i would like for this to be a free alternative for poor devs.
Sorry for the long post, and any thoughts regarding this will be greatly appreciated! If anyone is further interested, provide your email and i can write up a more detailed explaination with diagrams.
**Edit: I've got a professional web developer who is a friend of mine on the Site side of things
I'll be keen to help out on the Web Side of things. Looks like M$ Apps is gonna be a failure.
Email me: 89jase<at>gmail<dot>com
Hope a few people get on board, sounds like a great idea!
Thanks Jase!
I thought no one here wanted to help. I'll be in touch with some further details.
Though i still need a someone to point me in the right direction with the client side of it. Any help is greatly appreciated!
Stop developing such things, that already exists...
scilor,
Not that im trying to be rude when i say this, but why?
It's something i want to do, you havn't inputed contructively so why bother at all?
Futhermore, i do not know of a solution such as this currently developed. So if this is the case, perhaps you could link me to it? That would be helpful.
