Abstract: In network simulation, higher simulation accuracy generally leads to significantly increased computational overhead. To mitigate this issue, we present a new network simulation method for the focusing topology area (NESFOTA). The idea is to partition the topology into two parts that are complementary to each other, namely the focusing topology area and the non-focusing topology area. The focusing topology area is of interest to the simulation users and it is simulated using the traditional packet-level models to attain satisfactory accuracy. On the other hand, the non-focusing topology area is simulated with a higher level of abstraction to decrease the computational overhead. In particular, a method is proposed for the non-focusing topology area simulation, and theoretical analysis shows that it degrades marginally the simulation accuracy of focusing topology area. Compared to the traditional method, the NESFOTA method reduces the computational overhead by about 10 times at most while achieving nearly the same simulation accuracy of focusing topology area.
