Multitasking Arduino MEGA

I've been working on a project lately and i came across this thing using serial ports. It seems like i am not maximizing my serial ports on my ARduino MEGA. I know that the MEGA has more serial ports than arduino uno and how can I use these ports to use with my multiple sensors at the same time? thanks!

Look at the examples that come with the IDE. One of them is called "MultiSerial". Leo..
