You explain your results on the context of the subject!. That is you explain your results on the light of the expected behavior of your system under consideration.
The first thing is the shape of the curve, that is the variation of the packets to the base stations with rounds. It is clear that as the no of rounds increases the the packets per round decrease and ultimately approaching zero at large values of the round. This means that one not need to increase the number of rounds beyond specific value as the number of rounds increases the time required to route the packets increases.
The though put of your routing protocol is much higher than the previous one.
You have to bring reasoning for this enhancement based on your routing algorithm.
