How to use Alljoyn to make multi-play game

I wanna make AR multi-play game with Vuforia so i tried some networking services(f.g PUN,UNET) but it doesnt work. But actually i found that there are some AR multi-play games so i think to make AR multi-play game is possible.I hope so at least. And I noticed that I can make AR multi-play game with Alljoyn but to use it in Unity is difficult for me. I can't import Alljoyn in Unity at first. If you know how to use it in Unity,Pls tell me.
