we have done something similar for a mobile simulation package for ndnSIM (it was an NDN hackathon project). We have addressed those issues there, so please take a look at the commits:

This works perfectly on first transmission, but the Interest is not forwarded to other nodes which is in range with the receiving nodes (In other words, it is not forwarded, there is only 1 hop)

The problem is, it is using ndnSIM 1.0 and the custom strategy methods have been changed on ndnSIM 2.0+, which I am using right now. I've also read somewhere that nodes do not actually re-broadcast Interest and Data packets on the same face it received the packet from.
