Is it possible to automatically start my application when device restarts? Can we use push notification to invoke the application when device restarts?

For your first question no it is not possible without JailBreak, you cannot open app without user interaction, although there is an exception for VOIP-enabled app.

more info: Can iPhone apps start on start-up?

For second question yes you can open app with push notification.

more info: Open app at specified page with Push Notification

Edit:

You can get the payload from launchOptions as below: 

- (BOOL)application:(UIApplication *)app didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    NSDictionary* payload = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    if (payload) {
        // process the payload here
    }
    [window addSubview:viewController.view];
    [window makeKeyAndVisible];
    return YES;
}

Take a look at the UIBackgroundModes section in this document - it seems to state that adding the voip key will autostart an app on boot.

Try this sample code

a sample app seems to confirm this behavior.
