I don't want other computers connect with my computer, I don't want sharing my macbook pro, so how I can protect my computer and avoid other people connect with my computers

As long as you do not enable Sharing of any kind (System Preferences > Sharing) no other computer can connect with yours. Also make sure you have your wireless network protected with a WPA2 password.

That's all I can suggest without knowing what OS version you are running (you are not running iOS as that is for iDevices).

You're welcome! For easier troubleshooting in the future, please update your profile to show which Mac OS version you are running and what model MBP.
