The class of flooding-based DTN routing protocols that leverage (transitive) encounter probabilities have been shown to perform well in selected simulations and scenarios, however they are especially sensitive to heterogeneous mobility models in which some nodes’ mobility pattern is on a significantly differ- ent timescale than others. In particular, military and disaster response scenarios can exhibit abrupt topology changes. We analytically show that the worst-case inputs to these existing DTN routing algorithms can drastically reduce their performance. In light of such scenarios, we develop new protocols that inherit the benefits of existing schemes, while leveraging geographic assis- tance to enable faster recovery from abrupt topology changes.
