Compared to wired networks, Delay Tolerant Networks are challenging to monitor due to their lack of infrastructure and the absence of end-to-end paths. This work studies the feasibility of monitoring such DTNs. More specifically, we focus on the efficient monitoring of intercontact time distribution (ICT) between DTN participants. Our contribution is two-fold. First we propose two schemes to sample ICT and estimate its distribution using monitors deployed within the DTN. Second, we evaluate this scheme over both simulated DTN networks and real DTN traces. Our initial results show that 1) there is a high correlation between the quality of sampling and the sampled mobility type, and 2) the number and mobility patterns of monitors impact the estimation of the ICT distribution of the whole DTN.
