After each node allocates slots by distance-2 graph coloring, each source node transfers one packet in its allocated slot.
Indeed, to achieve multihop communication with the multi-sources scenario, more multipath routing have been constructed and selected independently (e.g., by flooding a control message from each source node and having each node remember the reverse selected paths to the sink) for data routing.
First, for each source node, n T singular values are obtained by singular value decomposition (SVD) of the channel from each relay transmit antenna to the source node, denoted by η ij (j=1,2,⋯,n T i=1,2).
By combining the transmission power of the source node and the transmission power of the cooperative interference node, each source node always minimizes the payment of its own.
That is, 320 data subcarriers of each source nodes are coded by using 960 subcarriers.
To evaluate the performance, we have considered three evaluation criteria: the PDR, the end-to-end delay, and the average number of packets forwarded by the network (Av. PKT), for each information packet produced by the source node.
Another important function of TCP is the end-to-end reliability control, through which each unacknowledged segment is retransmitted by the source node once the RTO is due, until the segment is positively acknowledged.
The value of, which determines the amount of redundancy to be introduced in each combined packet (i.e., the code rate), is chosen by the source node considering the physical channel between source node and sink.
