. ’s is 66% to 74% percent lower than the . Average latency is 52% to 108% higher. As buffer size increases, the difference in average latency between and the increases. Message replication overhead is 19% to 31% lower in . Larger message buffers and higher speed radios increase the message replication overhead performance gap between simulators.

Epidemic’s and average latency increase asymptotically with buffer size. Message replication overhead decreases with larger message buffers, the shows a steep decrease compared to ’s shallow decrease in message replication overhead. Both versions of Epidemic show that average latency increases asymptotically with larger message buffers. Epidemic’s performance in is close to the in Table \[tab:OmEpdPerfDiff\]. ’s is within 35% of the , and the simulators match at several data points. At small buffer sizes, has lower latency than the , but large message buffers show has higher latency. With respect of message replication overhead, ’s message replication overhead is 60% to 83% lower than the . Higher transmission speeds increase the performance gap in message replication overhead between and the .
