The routing performance of Delay Tolerant Networks (DTN) is highly correlated with the distribution of Inter-Contact Times (ICT), the time-period between two successive contacts of the same two mobile nodes. As humans are of-ten carriers of mobile communication devices, studying the patterns of human mobility is an essential tool to understand the performance of DTN protocols. From measurement studies of human contact behaviors, the authors find that their distributions closely resemble a form of power-law distributions called truncated Pareto. Human walk traces has a dichotomy distribution pattern of ICT; it has a power-law tendency up to some time, and decays exponentially after that time.
