Simulation-Based Performance Comparison of VANETs Backbone Formation Algorithms
Bibliographic record
Abstract
Mobile ad hoc networks (MANETs) are gaining increased interest as the technology that potentially will make the nowadays illusion of mobile computing a tangible reality. vehicular ad-hoc networks (VANETs) are the special kind of MANETs that aims at providing communications among vehicles on the roads. The connected dominating set (CDS), a.k.a. virtual backbone or spine, has been proposed to facilitate routing, broadcasting, and establishing a dynamic infrastructure for distributed location databases in VANETs. Minimizing the CDS cardinality simplifies the VANETpsilas abstracted topology and allows for using shorter routes. Since, it is NP-complete to find the minimum size CDS (MCDS), approximation algorithms and heuristics are used to tackle this problem. It has been reported that localized CDS creation algorithms run fast and generate light signaling overhead. Some theoretical performance analysis of these algorithms is presented in the literature; however, this analysis has not been validated across any physical or at least simulation-based measures. Moreover, the cost of maintaining the CDS in the presence of topology changes is an important cost that is overlooked most of the time. In this paper, a simulation-based comparison between the performance of these algorithms is conducted using the ns2 network simulator. Moreover, the effect of mobility rate and network size on the performance of each algorithm is investigated.

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.
