Solutions to Support Mobility in SDN-Based Dense Wireless Networks
Bibliographic record
Abstract
The software-defined networking (SDN) concept is an efficient solution to manage highly complex wired networks, such as large-scaled data centers and fixed Internet network. The basic idea of SDN is to separate the control and data forwarding functions of routers so that the traffic engineering (TE) optimization can be dynamically made by a central controller. However the application of SDN concept in dense wireless networks is not straightforward. Unlike wired networks, the channel capacity of wireless networks always changes, depending on the mobility of users, channel fading and interference. In dense wireless networks with mobile users, the impacts of varying channel capacity are more difficult to handle because of small cell size. In this paper, we propose SDN-based integrated solutions to support user mobility in dense wireless networks. Our solutions include traffic engineering, dynamic placement of virtual user gateway, and fountain coding. Our simulation results from a SDN-based simulator show that our solutions bring remarkable gains compared with conventional solutions.

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.
