Abstract: Present new mechanisms for modelling multiple interfaces on a node, support for interference-limited links and a frame-work for modelling complex applications running on the nodes. Furthermore, provide an overview of concrete use cases where the simulator has been successfully exploited to study a variety of aspects related to opportunistic, message-based communications. Node movement is implemented by movement models. These are either synthetic models or existing movement traces. Connectivity between the nodes is based on their location, communication range and the bit-rate. The routing function is implemented by routing modules that decide which messages to forward over existing contacts. Finally, the messages themselves are generated either through event generators that generate random traffic between the nodes, or through applications that generate traffic based on application interactions. The main functions of the simulator are the modelling of node movement, inter-node contacts using various interfaces, routing, message handling and application interactions. Result collection and analysis are done through visualization, reports and post-processing tools.
