In particular, in order to allow to UAVs to dynamically improve their 3D locations in a distributed fashion while maximizing the network's sum-rate, we break the underlying optimization into 3 subproblems where we separately solve the 2D UAVs positioning, the altitude optimization, and the UAVs-users association. First, given fixed 3D positions of UAVs, we propose a fully distributed matching based association that alleviates","authors_text":"Basem Shihada, Hajar El Hammouti, Mohamed-Slim Alouini, Mustapha Benjillali","cross_cats":["cs.GT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2018-10-15T06:41:02Z","title":"Learn to Fly: A Distributed Mechanism for Joint 3D Placement and Users Association in UAVs-assisted Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1810.11528","kind":"arxiv","version":1},"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":"sha256:4a651c18ebe3709df28b218c3d317e9ced7b9f00ee7f1593d9ed920024a3246e","target":"record","created_at":"2026-05-18T00:02:08Z","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":"07ae3f3ea33170891eb36dad20f2e2da2cc302ec6d8a2307038f8395223454b3","cross_cats_sorted":["cs.GT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.SP","submitted_at":"2018-10-15T06:41:02Z","title_canon_sha256":"e0e26f424166d648bd2e5ae05eb4d0b6446376b1d1dc2bc5a38524c155f036ba"},"schema_version":"1.0","source":{"id":"1810.11528","kind":"arxiv","version":1}},"canonical_sha256":"514853091d550aedd51f1c5c698e4b10b9f257ebe3c9e287cc531cd563b124a9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"514853091d550aedd51f1c5c698e4b10b9f257ebe3c9e287cc531cd563b124a9","first_computed_at":"2026-05-18T00:02:08.375145Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:02:08.375145Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"k5UrBldGKGoIYBcxcpCW6hOfXuLsQARACkMWRWMk8F9aHXQDm55jnaa/ZH/YcMW9JE03Ix9perGayTSmAE68Dg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:02:08.375847Z","signed_message":"canonical_sha256_bytes"},"source_id":"1810.11528","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4a651c18ebe3709df28b218c3d317e9ced7b9f00ee7f1593d9ed920024a3246e","sha256:7e0c78fecc26a8b43316b4655495fca15422b627f675bd2af81d47fc79002e04"],"state_sha256":"860ee7b93152ea119997d9ebe2be579b5c88683f73a3f0f7c1e1de662403b17d"}
