00021  * Node which interfaces to DTN2  and Simulator.
00022  * This node is responsible for forwarding/converting events
00023  * from Simulator to DTN2 and vice-versa.
00024  * It acts as  BundleDaemon. On receiving bundles/contact dynamics
00025  * etc... it informs the BundleRouter and  executes the returned
00026  * list of action. The actual forwarding of a Bundle using the
00027  * Simulator is done at the SimulatorConvergence layer.
