I solved my AdMob problem. I got my publisher id by this way

1. Login your AdMob account
2. Go to Sites&Apps.
3. View your sites given below, which are developed by you.
4. Just move curser to the app or site, two boxes will show named as Reporting and Manage Settings.
5. Hit Manage Settings and view your Publisher id there.

Note: Your iphone or iPad name and your admob app name should be same. Then AdMob will run on simulator also.
