Abstract
As traditional “Connectivity” concept from the Internet ignores the possibility of opportunistic contacts in DTNs, this paper brings time dimension into consideration, proposes Spatial-Temporal Path, Spatial-Temporal Reachability and K-Reachability in order to better describe the whole communication process and “Eventual Transportability” of DTN. Analytical and simulation results are given to show the correctness of our approach. Furthermore, Spatial-Temporal Reachability and K-Reachability, which tell a network’s robustness in a quantitative fashion, are proved to be suitable for analyzing efficiency and routing performance of DTNs.
