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

Nguyen, N. T., Lee, K., & Dai, H. (2019, March 21). IEEE Transactions on Vehicular Technology.

By: N. Nguyen *, K. Lee * & H. Dai n 

author keywords: Tabu search detection; massive MIMO; ordering schemes
topics (OpenAlex): Advanced MIMO Systems Optimization; Advanced Wireless Communication Techniques; Cooperative Communication and Network Coding
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)

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

Selvanayagam, A. H. A., Wang, Y., Jiang, N. H., Lee, N. K., & Rhee, N. I. (2012, January 1).

By: A. Selvanayagam n, Y. Wang n, N. Jiang n, N. Lee n & N. Rhee n

topics (OpenAlex): Peer-to-Peer Network Technologies; Caching and Content Delivery; Internet Traffic Analysis and Secure E-voting
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 Lévy walks and Lévy flights

Lee, K., Kim, Y., Chong, S., Rhee, I., & Yi, Y. (2011, April 1).

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

topics (OpenAlex): Human Mobility and Location-Based Analysis; Opportunistic and Delay-Tolerant Networks; Advanced MIMO Systems Optimization
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

Rhee, I., Shin, M., Hong, S., Lee, K., Kim, S. J., & Chong, S. (2011, April 15). IEEE/ACM Transactions on Networking.

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
topics (OpenAlex): Opportunistic and Delay-Tolerant Networks; Human Mobility and Location-Based Analysis; Mobile Ad Hoc Networks
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

Lee, K., Hong, S., Kim, S. J., Rhee, I., & Chong, S. (2011, November 10). IEEE/ACM Transactions on Networking.

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
topics (OpenAlex): Opportunistic and Delay-Tolerant Networks; Human Mobility and Location-Based Analysis; Evacuation and Crowd Dynamics
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.
