I assume every sensor have fix location

What do you mean by "location" here?

so my problem if I change one of sensor with the new one, the position of sensor become change.

Again, what do you mean by "position" here - surely you know where you put it?!

Do you mean "address" or "ID"?

It cause from my rom table

What is "your ROM table"?

Does anyone have idea to make it simple in program?

1-Wire is specifically designed as a bus; ie, for multiple sensors.

It's easier if you know the addresses (IDs) of the devices in advance, but the 1-Wire documentation includes a scheme to discover the device addresses if you don't...

I seem to remember that Peter Danneger published an alternative algorithm here some time ago...
