First of all, it depends on the level of detail of your simulation. SimulaQron does not take into account noise, so I presume your simulation is only functional. Many BB84 functional simulations have been developed so far, and no one was so interesting to deserve publication in a research paper.
Notice also that BB84 is the reference example in the following tutorial by the authors of SimulaQron:
If you want to simulate BB84 in a detailed fashion, you may try QuISP, a novel simulation tool whose focus is "on protocol design and emergent behavior of complex, heterogeneous networks at large scale, while keeping the physical layer as realistic as possible."
