QR-Decomposition-Aided Tabu Search Detection for Large MIMO Systems

IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY, 68(5), 4857–4870.

By: N. Nguyen *, K. Lee* & H. Dai n 

author keywords: Tabu search detection; massive MIMO; ordering schemes
TL;DR: An improved TS algorithm based on the QR decomposition of the channel matrix (QR-TS), which allows for finding the best neighbor with a significantly lower complexity compared with the conventional TS algorithm. (via Semantic Scholar)

2012 conference paper

Reducing redundant cross-ISP traffic in peer-to-peer systems via explicit coordination

2012 ieee consumer communications and networking conference (ccnc), 603–607.

By: A. Selvanayagam n, Y. Wang n, H. Jiang n, K. Lee n & I. Rhee n

TL;DR: This paper proposes a fine-grained mechanism called Swarm-over-Swarm (SOS), which is much more effective in reducing redundant cross-ISP traffic than existing schemes and implemented in both NS-2 and a real BitTorrent client. (via Semantic Scholar)

Delay-capacity tradeoffs for mobile networks with levy walks and levy flights

2011 proceedings ieee infocom, 3128–3136.

By: K. Lee n, Y. Kim *, S. Chong*, I. Rhee n & Y. Yi *

TL;DR: The asymptotic characterization of the joint spatio-temporal probability density functions of Lévy models, the order of critical delay, the minimum delay required to achieve more throughput than Θ(1/√n) where n is the number of nodes in the network, is obtained. (via Semantic Scholar)

On the Levy-Walk Nature of Human Mobility

IEEE-ACM TRANSACTIONS ON NETWORKING, 19(3), 630–643.

By: I. Rhee n, M. Shin  n, S. Hong*, K. Lee n, S. Kim* & S. Chong*

author keywords: Delay-tolerant network (DTN); human mobility; Levy walk; mobile ad hoc network (MANET); mobile network; mobility model
TL;DR: It is shown that many statistical features of human walks follow truncated power-law, showing evidence of scale-freedom and do not conform to the central limit theorem. (via Semantic Scholar)

SLAW: Self-Similar Least-Action Human Walk

IEEE-ACM TRANSACTIONS ON NETWORKING, 20(2), 515–529.

By: K. Lee n, S. Hong*, S. Kim*, I. Rhee n & S. Chong*

author keywords: Delay-tolerant network; human mobility; Levy walk; mobile ad hoc network; mobile network; mobility model
TL;DR: The main contribution of this paper is to present a mobility model called Self-similar Least-Action Walk (SLAW) that can produce synthetic mobility traces containing all the five statistical features in various mobility settings including user-created virtual ones for which no empirical information is available.
