Minimizing Interference in WiMax/802.16 Based Mesh Networks with Centralized Scheduling
Bibliographic record
Abstract
WiMax/802.16 mesh network is an emerging infrastructure that offers a cost-effective deployment for highspeed wireless broadband access to the back haul network. However, as in most wireless multi-hop networks, WiMax/802.16 mesh suffers from interference that decreases considerably the throughput and spatial reuse of the network. Interference in WiMax/802.16 mesh is a result of several phenomena, namely concurrent transmissions in the neighborhood and data collisions (that need to be avoided) at a receiver from transmitting nodes that are outside the range of each other (hidden terminal nodes). In this paper, we study the problem of minimizing iInterference (MI) in WiMax/802.16 mesh centralized scheduling networks by appropriately routing end connections and assigning slots to them. The proposed model includes the effect of hidden terminal nodes as well as the interferences coming from neighboring nodes. Results show that power-aware routing and adequate frame size selection yield better network performance, a consequence of the improved network spatial reuse.

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.
