I'm not sure, if it's the right place here to ask this question.
But can anybody explain more detaild, how sim-based mobile phone tracking's working, und if it costs anything (the second part is very important)?
The Wikipedia article explains it pretty well:
Mobile phone tracking tracks the current position of a mobile phone even on the move. To locate the phone, it must emit at least the roaming signal to contact the next nearby antenna tower, but the process does not require an active call. GSM localisation is then done by multilateration based on the signal strength to nearby antenna masts.
So as soon as your phone is turned on, it starts to emit signals that the antennas catch. If several of them receive the signal, that (and the signal strength) gives a pretty good indication of your location.
It needs a bit of software (which the law requires today), so it doesn't cost anything "extra" for the people that provide the hardware. It's not free for normal people to use, though.
sim based? mobile phone tracking goes in layers, just like PC. At first GPS, if phone don't have it then it counts what mobile providers towers covers the phone and how strong mobile signal is from each tower, so by that it can counts you location. It Don't cost for telephone companies but it might for you since it depends on connection provided by towers. So its not the thing you can do without providers knowing it.

I have 3 heos speakers in my house and a 4th wireless (wifi) speaker that I built myself. I was wondering if anyone else has tried tinkering around with the heos app to make it detect other wifi speakers and play music to them?
I tried using dlna to get my logitech/squeeze boxes and heos speakers to play the same music, which worked but there was a significant delay between the two systems that I couldn't correct with the squeezebox software settings.
Right now the only way to hook up to existing speakers is with a HEOS Link, but that is a pretty large and costly device. It would be great if Denon created a playback-only HEOS dongle that with a line out--call it a Linklite. It wouldn't necessarily need to be able to do everything a normal HEOS device does, at a minimum it would just play what is played to your other HEOS device(s). But nearly all wifi speakers have a line-in jack, even Sonos. It would be kind of cool to be able to easily add third party components in this way.
Wishful thinking: if HEOS becomes a more popular home entertainment operating system, perhaps vendors of the other products will embed the software required to be compatible with HEOS.

i am planning to build an ios application in which system can locate the device position with time being for specific place only within a building.. Such as when student entered into the school and if the student has attended the certain lecture or not and if has then for how long he/she has been on that certain class room? However, i don't have the clear idea about what is the best way to implement device locator and how the data is achieved from the device..i have just starting list out the features and design server side structure and it would be much more better to have clear picture of those things. So, can you guys please suggest me something better or some source where i gain detailed idea about that? thanks in advance.
I agree with MMR. You want use iBeacons, and Apple's Core Location framework.
You'd put a beacon at each location you want to monitor.
You set up "beacon regions" and the system notifies your app when the user enters or exits one of those regions.
On challenge you will face is that the system only allows an app to monitor at most 20 regions at a time. There are ways to deal with this, but it takes deep understanding of how beacon regions work and some creative work.
I am working on an app for a client right now that makes heavy use of beacon regions and is able to track a nearly unlimited number of beacons.
Google for iBeacon. It seems to be a perfect fit for the use-cases listed by you.
Also refer to this link for Apple documentation on iBeacon.

This question pops up in my mind as in many developing countries at present internet connectivity is very poor or no connectivity at all and the customer base is very huge, in this case how IoT can help in making life easy?
There are currently a few projects going on whose purpose is to provide an affordable Internet access for people in poor areas:
https://en.wikipedia.org/wiki/Project_Loon
https://en.wikipedia.org/wiki/Internet.org
https://en.wikipedia.org/wiki/Outernet
There are also technologies such Wi-Fi Direct that do not require presence of a centralized servers.
Lastly, as others said, IoT developers will have to deal with lack of connectivity and design their software accordingly.
You could even go a step further, many machine-to-machine solutions will have incredibly low bandwidth. (Take for example LoraWan which would be extremely suitable to roll out in developing countries).
So, being in a developing country or not, you are stuck with networks and devices that have to deal with low bandwidth anyway. This means that the developers creating the software for your devices need to think very well about how they solve certain type of problems.
A lot of devices currently also have to deal with situations where there is no connectivity at all. For example a tracking device in a container on a ship.
This device should be built in a way, that it will function without a proper internet connection.
Conclusion:
IoT devices can work with low bandwidth connections.
Development should be done with the idea of non-connectivity in mind.

I am writing an IOS app and want to be able to connect to IoT devices (get data from them). I want to be able to search an area for IoT devices i can connect to; (whether they be weather stations, seismographs, etc) (and potentially filter out devices of some sought if possible).
Is there an API which offers this? (finding IoT devices in an area), if not, is there another fairly straight forward way i could do this?
There is no way to simply "search for IoT devices". I'm afraid that you might have a misunderstanding of IoT devices are and how they exchange data. They can send data via bluetooth, wifi, etc. so not knowing what listen to is your first challenge. Second challenge is that even if you could see all of them and lets say but some super natural force you can connect to them, you'd have no idea the format of the data. A seismograph could be pumping out data that looks just like a weather station data.

Should HIPAA complinace not allow offline storage in Mobile Native Applications??I dont know if already there is this sort of regulation in HIPAA. I assume there is no such thing.
If you feel this question need not be asked in this forum, I request you to completely read this and suggest a programmatic solution for this problem.
Main reason why this came up was that all of the security considerations regarding the Mobile development may be specifically in iOS seems to have been hacked in to once a device is jailbroken or rooted.
I came to know that hardware encryption is hacked.
http://anthonyvance.com/blog/forensics/iphone_encryption/
Then there are questions on iOS 4's encryption techniques.
People claim, Key chain access in iOS can be compromised if the phone is rooted.
Only thing I think which has not met with any skepticism is the sqlCipher.
If you could find any flaws with SqlCipher , please share it.
And I think that, until people find a theft-proof way to manage offline data in Mobile Phones, people can refrain from making offline features for EMR apps where HIPAA compliance is mandatory.
It can be argued that, any system can be hacked when people are desperate to hack it. But I feel Mobile devices can be an easy target. You can lose it as you lose your Handkerchief.
Please share your views.
I agree with bshirley. Your surface of vulnerability is much greater if you are storing many records about many people on the device. But if you are only storing limited info about one person temporarily - as when conducting a query for prescription info or gathering information about a current health problem - then the risk is much lower. Of course you also need to consider whether the hacked phone presents a security risk to the online data, that is, does the app on the phone enable a wrong user to access protected data online?
