In Multicast, since almost simultaneous communication take place along several branches of a Multicast distribution tree, these branches tend to mutually block each other due to interference. We utilized a model of scheduling in automobile production line called GORBY to divide the nodes in the Multicast distribution tree into three groups (GORby-Group or GG). We calculate the SINR of the node based on interferences caused by all the nodes within that GG, assuming when the given node is in the transmit state then all the nodes within its GG will also be in the transmit state. Finally we use the computed SINRs in our join Multicast group algorithm to achieve the most SINR, which we call it GORby Interference-Aware (GIA) metric in case of a node, and Path GIA (PGIA) in case of a path.
