A channel accessing scheme with joint detection receivers in ad hoc networks
Bibliographic record
Abstract
In order to achieve high capacity packet transmissions in wireless ad hoc networks, the system throughput for a connectionless, distributed channel accessing scheme exploiting joint detection receivers is proposed and analysed. Joint detection allows many concurrent, asynchronous packet transmissions to occur, thereby enhancing the capacity of a system. A novel packet format with physical layer header's containing an additional code identifier (CID) field as proposed by P. Gupta and P. R. Kumar (March 2000) is employed and CSMA is used for the physical layer header (PLH) of the packet. The data portion of each packet is spread by a unique random binary signature sequence identified by the code identifier field (CID) which allows joint detection of the asynchronous, overlapping packets. A comparison of using CSMA and Aloha multiple access for the PLH is made for a bimodal packet length distribution typical in TCP traffic. Further, an upper hound on the throughput capacity considering the proposed channel accessing schemes is given indicating a significant improvement of system and network throughput is possible with respect to conventional methods.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
