Here, two-hop relay-assisted cooperative communications using opportunistic relaying (OR) is proposed for enhancement of coexistence for WBANs. Suitable time division multiple access (TDMA) schemes are employed for both intra-WBAN and inter-WBANs access protocols. To emulate actual conditions of WBAN use, extensive on-body and inter-body \"everyday\" channel measurements are employed. In addition, a realistic inter-WBAN channel model is simul","authors_text":"David Smith, Jie Dong","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/3.0/","primary_cat":"cs.NI","submitted_at":"2013-05-30T02:58:34Z","title":"Coexistence and Interference Mitigation for Wireless Body Area Networks: Improvements using On-Body Opportunistic Relaying"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1305.6992","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":"sha256:9bb4994c59a49bc916f83e9dfc5ed01889b14871b5fdeb0fd847e5b13284e190","target":"record","created_at":"2026-05-18T03:22:16Z","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":"c673bccfd84a47d9af0f81e1b0dfdf9daaab6a10c1e2f46ae024fd1c09b80628","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/3.0/","primary_cat":"cs.NI","submitted_at":"2013-05-30T02:58:34Z","title_canon_sha256":"289e016a87575a7be3a884f15b15f48a3beea253aaba3adf7ee1ae8bd15aeb6a"},"schema_version":"1.0","source":{"id":"1305.6992","kind":"arxiv","version":1}},"canonical_sha256":"36dfd7012e43779e4475be0e4e74942d38f0cf9e6b0c5c4e20b0275ba54951f1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"36dfd7012e43779e4475be0e4e74942d38f0cf9e6b0c5c4e20b0275ba54951f1","first_computed_at":"2026-05-18T03:22:16.686687Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:22:16.686687Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"EnfEJBAxAJAazSy/6FNGxzrudbdUfdBHrk179vlyVWs32uE5qSHlWU4QtwqzsAjkgWx6JA22qBFvpLVNv827AA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:22:16.687172Z","signed_message":"canonical_sha256_bytes"},"source_id":"1305.6992","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9bb4994c59a49bc916f83e9dfc5ed01889b14871b5fdeb0fd847e5b13284e190","sha256:a64cdfae1d21c6c832ee3d2a1af6a01e26227456038fb2b3e594e95949a2efb9"],"state_sha256":"b9675466530be4f14ca78eba1e129b267fb280dfaf7365368734ed77b9f70142"}
