There's no way to get those figures from the publicly documented APIs (and I don't quite know what you mean by 'network traffic of GPS', because GPS isn't a network protocol). So the answer to your question is: no, nobody can suggest it, because it's not possible within the public APIs.

You can probably do it using undocumented classes or on jailbroken devices, but if you're looking to put your app on the app store there's no point considering that because it will just get rejected.
