Abstract
Network-wide Broadcast is one of the most fundamental services in wireless sensor networks (WSNs). It facilitates sensor nodes to propagate messages across the whole network, serving a wide range of higher-level operations and thus being critical to the overall network design. A distinct feature of WSNs is that many sensor nodes alternate between the active state and the dormant state, so as to conserve energy and extend the lifetime of the network. Unfortunately, the impact of such cycles has been largely ignored in existing network-wide broadcast implementations that adopt the common assumption of all sensor nodes being active all over the whole broadcast process. In this chapter, we first provide a brief survey on previous research works on network-wide broadcast services. We then revisit the network-wide broadcast problem by remodeling it with active/dormant cycles and showing the practical lower bounds for the time and message costs, respectively. We also propose an adaptive algorithm named RBS (Reliable Broadcast Service) for dynamic message forwarding scheduling in this context, which enables a reliable and efficient broadcast service with low delay. The performance of the proposed solution is evaluated under diverse network configurations. The results suggest that the proposed solution is close to the lower bounds of both time and forwarding costs, and it well resists to the network size and wireless loss increases.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
