Abstract DTN(Delay-Tolerant Network) describes the situation in which longtime partition often happens. DTN doesn’t assume the existence of End-to-End path, so it focuses on successful delivery ratio of packets. Nodes’ mobility model such as group, is an attractive field in DTN research; this paper concentrates on Macro-Mobility and presents a framework to detect and use mobility models? TOM2D(Template-Operation based Mobility Model Discovery). The main idea is: each node maintains a 3D matrix which contains the capacities of links through routing information exchange, then detects the mobility models from the matrix by template-operations, and stores them in a universal data structure at last. This paper gives an example of using TOM2D in OLSR and DSDV, and the results of simulation show that TOM2D performs well.
