The main challenge in these networks is to develop a mechanism based on which nodes can learn to make nearly optimal forwarding decision rules despite having no a-priori knowledge of the network topology. The forwarding mechanism should ideally result in a high delivery probability, low average latency and efficient usage of the network resources. In this paper, we propose both centralized and decentralized single-copy message forwarding algorithms that, under relatively stro","authors_text":"Mark Coates, Shohreh Shaghaghian","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.NI","submitted_at":"2015-06-15T19:49:48Z","title":"Optimal Forwarding in Opportunistic Delay Tolerant Networks with Meeting Rate Estimations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1506.04729","kind":"arxiv","version":4},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:9b9cd54b6fbb538033ab1cc2da18f0a2f8337ae2e94a3a2224b87874473d4ab2","target":"record","created_at":"2026-05-18T01:44:10Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"201accc9caf190322b5d2f5fa960ba3ccd2793bc1d424875e08bad70fb1da439","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.NI","submitted_at":"2015-06-15T19:49:48Z","title_canon_sha256":"3f55032ab53c07a83b73a27e8817996990316332250ee130572ddcadd4d55928"},"schema_version":"1.0","source":{"id":"1506.04729","kind":"arxiv","version":4}},"canonical_sha256":"3454568dd1719a7521e729f4a2b5f1395a85bb4463c86e72daf622dd70506c55","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3454568dd1719a7521e729f4a2b5f1395a85bb4463c86e72daf622dd70506c55","first_computed_at":"2026-05-18T01:44:10.780403Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:44:10.780403Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"7AC5QvbqcExhFnKxw/qNp/GBYcYTPdHQbOKAny3LZUoxcVmolrpwp6W+rluGtvyNynZGQBEcPJhWS91YFQgCCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:44:10.781209Z","signed_message":"canonical_sha256_bytes"},"source_id":"1506.04729","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9b9cd54b6fbb538033ab1cc2da18f0a2f8337ae2e94a3a2224b87874473d4ab2","sha256:818cb29997150fc50b74af07fccbc6866c8feaecb2944be3c22ee0e824b7b296"],"state_sha256":"e2d320e7365cd22b4141717644e030da57e17aa8455df32e16149db48fe19ab8"}
