Abstract

As wireless networking technologies have evolved, wireless networks are deployed in wider areas. In some of them, end-to-end paths may not be guaranteed due to high mobility or low density of network nodes. Delay/Disruption Tolerant Networks (DTNs) or Intermittently Connected Networks (ICNs) are proposed to handle packet delivery in those networks. In DTNs, network simulation may play a critical role for developing new technologies since it is very expensive and time-consuming to perform real experiments. In this paper, we present a new simulation tool for DTNs. This tool is developed with an event-driven manner to accommodate discrete events in packet delivery processes in DTNs, and also it is highly flexible and easily extensible for developing new protocols. We validate the tool with well-known mathematical models of DTNs.
