Feedback Based Real-Time MAC (RT-MAC) Protocol for Wireless Sensor Networks
Bibliographic record
Abstract
This paper presents a MAC layer protocol, called RTMAC, for real-time data streaming in wireless sensor networks. RT-MAC eliminates need to contend for a wireless medium by potential transmitting nodes in a range by introducing feedback control packet, called Clear Channel (CC). RT-MAC maximizes spatial channel reuse by avoiding false blocking problem of RTS/CTS exchange based wireless MAC protocols. RT-MAC reduces contention duration for control packets to facilitate faster traveling of data packets; thus, it reduces end-to-end delay of data packet transmission. RT-MAC facilitates periodic delivery of data packets as well as fast reporting of an alarming event. This paper provides the upper bounds of end-to-end delay of data packet transmission with periodic sleep/listen schedule for RT-MAC protocol. In this paper, extensive simulation results are presented. RT-MAC supports single stream communication between a randomly selected source and sink node pair as well as multi-stream non-interfering communication among different source and sink node pairs.

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.
