Optimal Rate Sampling in 802.11 Systems
TL;DR: This paper presents ORS (Optimal Rate Sampling), a family of (mode, rate) pair adaptation algorithms that provably learn as fast as it is possible the best pair for transmission and illustrates the efficiency of ORS algorithms (compared to the state-of-the-art algorithms) using simulations and traces extracted from 802.11 test-beds.
Journal ArticleDOI
Optimal Rate Sampling in 802.11 Systems: Theory, Design, and Implementation
TL;DR: This work rigorously formulate RA as an online stochastic optimization problem, and presents G-ORS (Graphical Optimal Rate Sampling), a family of provably optimal (mode, rate) pair adaptation algorithms that outperforms state-of-the-art algorithms such as MiRA and Minstrel HT.
Proceedings ArticleDOI
Virtual network embedding in wireless multihop networks
Donggyu Yun,Yung Yi +1 more
TL;DR: This paper considers network virtualization in wireless multi-hop networks, where a critical algorithmic component, virtual network embedding problem, is studied, and proposes a preliminary algorithm, which validates its performance.
Journal ArticleDOI
Embedding of virtual network requests over static wireless multihop networks
TL;DR: In this article, the authors study the root causes of new challenges of virtual network embedding in wireless multi-hop networks, and propose a new embedding algorithm that efficiently uses the resources of the physical substrate network.

Aggregating LTE and Wi-Fi: Toward Intra-Cell Fairness and High TCP Performance
TL;DR: This work proposes an easily deployable mechanism, called LTE-W, which efficiently utilizes LTE and Wi-Fi links only with the minimum change of eNodeBs, LTE backhaul networks, and mobile terminals, and compares it with a transport-level aggregation mechanism, multipath TCP (MPTCP), demonstrating that it significantly improves MPTCP, e.g., up to 75% in terms of Jain's fairness index.
