Baseline Baseline for comparing DTN performance end-to-end TCP connections idealized link state routing in underlay zero control overhead, instantaneous convergence shortest paths recomputed globally in emulator on each link event practical link state approaches unlikely to realize this performance lack of extraneous traffic in baseline allows fair comparison Other parameters are kept identical for DTN and baseline identical application software / overhead identical traffic load, topology, and link dynamics All metrics reported are from real system measurement extracted from dtnd logs and live packet traces from emulator the confirmation required 54 hours of experiment data |
