Abstract
Wireless Body Area Networks (WBANs) are widely used for applications such as modern health-care systems, where wireless sensors (nodes) monitor the parameter(s) of interest. Nodes are provided with limited battery power and battery power is dependent on radio activity. MAC protocols play a key role in controlling the radio activity. Therefore, we present Adaptive Medium Access Control (A-MAC) protocol for WBANs supported by linear programming models for the minimization of energy consumption and maximization of dataflow. Our proposed protocol is adaptive in terms of guard band assignment technique and sleep/wakeup mechanism. We focus on specific application to monitor human body with the help of nodes which continuously scan body for updated information. If the current value is within normal range, nodes do not try to access channel. However, if the current value rises or falls beyond the permissible range, nodes switch on their transceiver to access channel. Moreover, A-MAC uses TDMA approach to access channel and well-defined synchronization scheme to avoid collisions. Furthermore, we conduct a comprehensive analysis supported by MATLAB simulations to provide estimation of delay spread. Simulation results justify that the proposed protocol performs better in terms of network lifetime and throughput as compared to the counterpart protocols.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
