For wireless transmission from S1 to D1, either S1-X1 and X2-D1, or X1-X2, can operate at any given time slot

Intra-flow interference is interference between intermediate routers sharing the same flow path. Consider as an example, a 1-D linear network topology, where router A forwards a packet to router B, which then forwards to router C and so on, such that A is connected to C through B. Such a network will suffer from intra-flow interference, as link A-B and link B-C can not operate simultaneously. Therefore at any given time, either link A-B or link B-C can be operational.

In wireless routing, routing protocol WCETT[1], MIC[2] and iAWARE[3] incorporate consideration to the intra-flow interference metric.
