Special issue on ubiquitous wireless mesh networks
Bibliographic record
Abstract
Wireless mesh networks are becoming promising communication technologies for broadband wireless access by providing wireless backbone to mobile devices over multi-hop wireless communication systems. This emerging technology has a great potential for ubiquitous wireless network access anywhere and anytime. A number of wireless networking and communication technologies that support ubiquitous wireless services and applications are currently in wide spread use. Wi-Fi and WiMax-based wireless mesh networks are the examples of such technologies currently under deployment, fostering broadband wireless network access and supporting different communication ranges. While these technologies provide flexible communication compared with wired networks and single hop communication models, they are still restricted to the existing wireless backbone coverage. The convergence of ubiquitous computing and networking with wireless and mobile networking technologies opens a path to a promising opportunity for ubiquitous wireless mesh networks and services. Indeed, this provides a great potential for enabling ubiquitous wireless network access in the next generation mobile networks. However, due to the heterogeneous nature of networks, devices and services, ubiquitous multi-hop wireless access technology introduces new research challenges in all areas of network protocol stack, including security, interoperability and performance challenges. The main aim of this special issue of the International Journal of Communication Systems is to address some of the challenges described above and to publish state-of-the-art research results in the area of ubiquitous wireless mesh networks, with focus on innovative architectures, networking protocols, communication models, services and applications. We hope that this issue will be a useful reference for current and future research in the area of ubiquitous wireless mesh networks. We received 24 papers for this special issue from researchers across the globe. Each paper was reviewed by at least three qualified reviewers. Owing to space limitations we have accepted only four papers. The acceptance rate for this special issue is about 17%. The selected papers address important topics in wireless mesh networks covering security, cross-layer-based solutions for channel assignment, forward error correction and dynamic frame aggregation schemes. The first article, ‘FLSAC: A New Scheme to Defend against Greedy Behavior in Wireless Mesh Networks’ authored by Djahel and Nait-Abdesselam proposes a fuzzy logic-based scheme to defend against greedy behavior in wireless mesh networks. The proposed scheme is implemented in the mesh router/gateway to monitor the behavior of the attached wireless nodes and report any deviation from the proper use of the protocol. The simulation results of the proposed scheme show robustness and its ability to detect and quickly identify any adaptive attacker. The second article, ‘A Cross-Layer Architecture for Effective Channel Assignment with Load-Balancing in Multi-Radio Multi-Path Wireless Mesh Networks’ authored by Bononi, Felice, Molinaro and Pizzi proposes a cross-layer architecture that consists of a novel joint multi-path routing and channel allocation scheme in multi-radio wireless mesh networks. The proposed solution also includes a load-balancing scheme that allows the distribution of traffic among the available disjoint paths. The performance improvement was demonstrated in the simulation settings for different network topologies and traffic workloads. The third article, ‘An Adaptive Multi-hop Forward Error Correction Protection Scheme for Video Streaming over Wireless Mesh Networks’ authored by Tsai, Shieh, Hwang and Deng proposes a scheme that can achieve the timely loss recovery of streamed video by dynamically adjusting the number of sub-paths and the forward error correction redundancy level. The article presents experimental results that have shown that the proposed scheme yields a higher peak signal-to-noise ratio than either the end-to-end or hop-by-hop schemes. The results have also shown that the performance of the proposed scheme can be optimized by specifying an appropriate value of the control parameter in order to adjust the sensitivity of the scheme to changes in the network conditions. The last article, ‘Efficient Dynamic Frame Aggregation in IEEE 802.11s Mesh Networks’ authored by Lin, Yeh, Yang, Ku, Tsao and Lai proposes a novel dynamic aggregation selection and scheduling algorithm that can dynamically adopt the appropriate aggregation mechanism for IEEE 802.11s mesh network. The paper discusses the characteristics and benefits of three aggregation mechanisms. Simulation results demonstrate that the algorithm significantly increases the channel efficiency of the 802.11 MAC and further improves the overall throughput of the wireless mesh network.

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.
