Secrecy Based Resource Allocation for D2D Communication Using Tabu Search Algorithm
Bibliographic record
Abstract
Device-to-device (D2D) communications have been pro- posed as one of the key technologies to improve the spectral efficiency in the future fifth generation (5G) of wireless mobile communication systems through resource sharing with cellular networks such that it can offload the part of cellular traffic onto the D2D network. However, intra-cell interference in D2D underlying cellular systems may decrease the performance of wireless network. In this paper, we investigate the subcarrier allocation issue when employing physical layer security capacity of D2D pairs and cellular users (CUs). When secrecy-capacity take into consideration, D2D communications can help the cellular system to decrease intra-cell interference. In our optimization task, we formulate the subcarrier allocation problem to maximize the system secrecy-capacity while guaranteeing the minimum data rate requirements for all D2D pairs and CUs. Such optimization is NP-hard problem with nonlinear constraints and optimal solution can be found through complicated methods such as exhaustive search or branch-and-bound. We, therefore, propose tabu search (TS) meta-heuristic algorithm to globally find the optimal subcarrier allocation solution to maximize system secrecy-capacity. Simulation results show that the proposed TS scheme achieves a higher performance than other algorithms in term of system secrecy- capacity.

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.
