A variable neighborhood search method for multi-objective channel assignment problem in Multi-Radio WMNs
Bibliographic record
Abstract
Channel assignment schemes in Multi-Radio Wireless Mesh Networks (MR-WMNs) usually leave several links sharing the same channel within overlapped transmissions or interference ranges; this is especially true when only one radio is used or when the number of radios is very small compared to the number of orthogonal channels. In this paper, we propose a new multi-objective optimization model for channel assignment (CA) performed during the MR-WMNs planning process. Given the expected traffic demand, the goal is to (1) minimize user handoff overhead; (2) minimize traffic load variances to achieve load balancing; (3) maximize overall throughput; and (4) maximize Jain's fairness index to achieve fairness among mesh clients. We also propose a variable neighborhood search (VNS) meta-heuristic to solve our model. Simulation results show that our proposed approach achieves good performance in terms of delay, loss rate, overall throughput and fairness in the MR-WMNs.

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.
