We have implemented a real-life multi-node multi-antenna WPSN testbed that operates in real time. We propose a beam-splitting beamforming technique that enables a power beacon to split microwave energy beams towards multiple nodes for simultaneous charging. We experimentally demonstrate that the beam-splitting beamforming technique achieves the Pareto optimality. For a perpetual operation of the sensor nodes, we adopt an energy neutral contro","authors_text":"Arif Abdul Aziz, Dedi Setiawan, Dong In Kim, Kae Won Choi, Lorenz Ginting, Phisca Aditya Rosyady","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2017-02-17T10:29:45Z","title":"Theory and Experiment for Wireless-Powered Sensor Networks: How to Keep Sensors Alive"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1702.05290","kind":"arxiv","version":2},"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:f87391585ee6bba64dbe25e8847d8f4497eb4b023a4faa524cdba894c1814d32","target":"record","created_at":"2026-05-18T00:50:13Z","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":"cb27cf33352af586a2b342a2b97b280b07cae12e474837a32ba65002ca3adb8a","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2017-02-17T10:29:45Z","title_canon_sha256":"2aecbead02c36a4b0f86a8853cebffd4bca19fbf2d9d74ec0510501e62df98b8"},"schema_version":"1.0","source":{"id":"1702.05290","kind":"arxiv","version":2}},"canonical_sha256":"dd247fabecf8cb1010ec7252bf9b0088d8e8a886aafa172b4c793e5182b265ea","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"dd247fabecf8cb1010ec7252bf9b0088d8e8a886aafa172b4c793e5182b265ea","first_computed_at":"2026-05-18T00:50:13.337915Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:50:13.337915Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bogKAcnZPro0Ro3WNa7m8UhWhaCkwznjO0LeAz+rIXF5eFV/+1QNMgT/7nbarqENLXZa1KqvW6Ur2PUOjAEGCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:50:13.338429Z","signed_message":"canonical_sha256_bytes"},"source_id":"1702.05290","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f87391585ee6bba64dbe25e8847d8f4497eb4b023a4faa524cdba894c1814d32","sha256:508f5135329ad88c511936873472685515470406898ba54c6bdd817cce7b14e5"],"state_sha256":"313560659dc30e47f628496faabe9984abce1c900190999afecf39d8b927b407"}
