Scene-aware Self-adaptive Routing In Dtn

In DTNs, the network is quite sparse and the nodes hold high mobility, which is why most of the time there does not exist a complete path from a source to a destination, or such a path is highly unstable and may change or break soon after it has been discovered. So the mobility of node is the main aspect which affects routing's behaved. The pattern of node's connection and disconnection is quite different in distinct Movement Models, so a routing which can concentrate on this point is helpful for improving performance. However, in real world the Movement Model is varying, which causes that monitoring the varying of Movement Model and switching the routing subsequently become the basis of improving the packet delivery probability.Abstracted from real world, 4 typical node movement models have been gotten. In these 4 models, research is deployed on Scene Parameters which can embody features of the scenes, the Self-adaptive Routing which can identify the outside environmental changes automatically and finish the state changes. In the end, this paper gives out the experiment results about Scene Change of this Self-Adaptive Routing.
