Abstract
This paper discusses one of the issues that are not covered by current stepping stone detection based researches. Although dropped packet problems are well-known problem in real network environment, all of the stepping stone detection researches just assume that dropped packet problems do not occur. Stepping stone detection research already in complex condition where each enhancement of the research attempts to solve problem such as encryption, delay and chaff without focused to solve dropped packet issues. For that situation, this research believes that to make sure that dropped packet problem can be solved; it should begin from the beginning of the stepping stone research. In other words, to solve dropped packet problem, we must solve it at the early stage of stepping stone research without combine it with current complex condition of stepping stone research. For that purpose, experiment has been executed by using NS-2 to prove the existence of the dropped packet in stepping stone detection environment. The experiment has been setup for a basic stepping stone detection environment. From the result obtained, it shows that dropped packet definitely influences the detection of stepping stone.
