Certain limitations of reputation--based schemes in mobile environments
Bibliographic record
Abstract
Cooperation based on reputation--based trust schemes in mobile ad hoc networks has been proposed with the intention of securing networks against possible selfish behavior. Selfishness is defined as refusal of (non--malicious) nodes to participate in network activities such as packet forwarding. We analyze the effectiveness of one such cooperation enforcement mechanism, namely reputation--based cooperation, using a simulated ad hoc network environment. The energy consumption of selfish nodes is also analyzed, to identify whether selfish behavior is actually beneficial to a node, and thus, whether selfish behavior is something that might actually be observed in a real ad hoc network. We find that reputation--based cooperation enforcement is only effective in non--mobile ad hoc network environment, however, we also find evidence that selfish behavior may not have benefits when the cost of energy consumption of a node is considered.

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.
