Limitation of local detection in multihop topology. There are two flows f AD and f EG in this multihop topology. Node C is a coding node because ({A,G}, C, {D,E}) can be made as a coding structure of X topology. However, nodes B and F cannot overhear each other. This coding structure cannot be found if local detection is used. Hence, many coding opportunities are missed in this case.
