Opportunistic networks do not require the availability of an end-to-end path, but may instead take advantage of tem- porary connectivity opportunities. Opportunistic networks pose a challenge for network emulation as the traditional em- ulation setup where application/transport endpoints send/ receive packets from the network following a black box ap- proach is no longer applicable. Instead opportunistic net- working protocols and applications need to react to the dy- namics of the underlying network beyond what is conveyed through the exchange of packets. In order to support emula- tion evaluations for such challenging applications we in this paper introduce the concept of emulation triggers that can emulate arbitrary cross-layer feedback and that are synchro- nized with the emulated scenario. The design and implemen- tation of triggers in the KauNet emulator are described. The use of triggers in the context of opportunistic networking is brie y sketched.
