Algorithms Currently Implemented Several algorithms are implemented in KB PFLOOD, a pure flooding approach REPLIF, a replica forwarding approach with staggered attempts RANDWALK, a random walk based approach QUIKROUTE, a link state approach enhanced for DTN supports discovered, scheduled, and predicted link availability HYBRIQ, a hybrid approach using QUIKROUTE and RANDWALK Choice of strategy declared via dtnd command Many other algorithms and variants are possible experimentation limited by schedule constraints |
