Abstract

fetched live from OpenAlex

We present a new analytical model of MAC layer for wireless ad hoc networks that takes into account frame retry limits for four-way handshaking mechanism. This model offers flexibility to address key design issues such as the effects of traffic parameters and possible improvements for wireless ad hoc networks. It effectively captures the important network performance characteristics such as throughput, channel utilization, delay and average energy. Under this analytical framework, we evaluate the effect of RTS (request-to-send) state on unsuccessful transmission probability and its effect on the performance specially when the hidden terminal problem is dominant, the traffic is heavy, or the data frame length is very large. By using our proposed model, we show that the probability of collision can be reduced when using RTS/CTS mechanism. Thus, the throughput increases and, at the same time, the delay and the average energy to transmit the frame is reduced.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
