Abstract
This study introduces an innovative, terrain-aware optimization framework for wireless communication networks with three key advances. Departing from prior 2-D map-based approaches, our method explicitly evaluates 3-D terrain effects by incorporating high-resolution elevation data into Fresnel zone clearance calculations for both 900-MHz and 2.4-GHz transmissions, enabling precise link feasibility assessment. The process begins with terrain-constrained link evaluations to generate a visibility matrix, followed by integrating link constraints and bandwidth requirements into an enhanced density peak clustering (DPC) algorithm. In contrast to heuristic clustering techniques that empirically adjust hyperparameters, we derive the critical cutoff distance through rigorous analysis of free-space path loss and link budget constraints (accounting for transmit power, antenna gains, and receiver sensitivity), ensuring physically interpretable cluster formation. This optimized DPC approach identifies communication center locations tailored to 3-D terrain complexities and demand conditions. Next, the proposed optimization framework jointly considers terrain-aware connectivity validation, distance minimization for cluster-member associations, and load-balancing constraints on central points—all governed by verified physical propagation models. After determining center placements, a redundancy-aware optimization assigns noncenter points to minimize transmission delays while distributing traffic efficiently. Experimental results on real-world terrains demonstrate significant network reliability and efficiency improvements, particularly for emergency management and advanced communication deployments.

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
