To achieve a good balance between self-sustainability and reliability, partially WPSNs with a mixed power solution are desirable for practical applications. Specifically, most of the sensor nodes are wireless powered but the key sensor node adopts traditional wire/battery power for reliability. As a result, this paper mainly investigates optimal design for the partially WPSNs in which simultaneous wireless information and power transfer (SWIPT) is ad","authors_text":"Chengwen Xing, Guanghua Yang, Shaodan Ma, Shiqi Gong","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2018-06-26T07:06:49Z","title":"Optimal Beamforming and Time Allocation for Partially Wireless Powered Sensor Networks with Downlink SWIPT"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1806.09814","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":"sha256:57580b33f262c0359b3733d93a201e3cdfc312066bdf4080805c51810f671d92","target":"record","created_at":"2026-05-17T23:45:46Z","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":"4f46b17865f561c6d1287e2fa349d430d7bb1da03735db16767fae3f9487c574","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2018-06-26T07:06:49Z","title_canon_sha256":"e8fdb327abf8c370cd97fb116aea58a2df12d4db86260274a076a47ca7ad0b74"},"schema_version":"1.0","source":{"id":"1806.09814","kind":"arxiv","version":1}},"canonical_sha256":"818ff6382089a5c74918e02a20d8ba956ece6d83527c3d6e205df2cb80df391a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"818ff6382089a5c74918e02a20d8ba956ece6d83527c3d6e205df2cb80df391a","first_computed_at":"2026-05-17T23:45:46.787136Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:45:46.787136Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bv2UlU4NwPGU4SjzlKoY3LZUZ0q+FjeHkxri6oZ73DzmUF8T/pR8NzvNxeLOF4HtkSydAO6gvGG44vBv5B6jDA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:45:46.787740Z","signed_message":"canonical_sha256_bytes"},"source_id":"1806.09814","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:57580b33f262c0359b3733d93a201e3cdfc312066bdf4080805c51810f671d92","sha256:9780bdb6dd5d5ee1d3946aa4733bfae56301b7d57af04fc6c0809618d35d261e"],"state_sha256":"2a0e717629c4668311947af7ea72714654c27cdcb2cd0aba6bbf719c4f647316"}
