Exploiting Heterogeneity for Improving Forwarding Performance in Mobile Opportunistic Networks: An Analytic Approach

IEEE TRANSACTIONS ON MOBILE COMPUTING, 15(1), 150–162.

By: C. Lee n & D. Eun n

author keywords: Mobile opportunistic networks; heterogeneous contact behaviors between different mobile nodes; heterogeneity-aware forwarding policies; forwarding performance; performance analysis
TL;DR: An analytical framework is developed to quantify the performance gain achievable by exploiting the heterogeneity in mobile nodes' contact dynamics and derive a delay upper bound of a heterogeneity-aware static forwarding policy per each given number of message copies, which enables a quantitative study on the benefit of leveraging underlying heterogeneity structure in the design of forwarding algorithms.

Towards Distributed Optimal Movement Strategy for Data Gathering in Wireless Sensor Networks

IEEE TRANSACTIONS ON PARALLEL AND DISTRIBUTED SYSTEMS, 27(2), 574–584.

By: C. Lee n, J. Kwak n & D. Eun n

author keywords: Wireless sensor networks; mobile collectors; data gathering; Markovian random-walk movement strategies; distributed optimal movement strategy; network loss probability
TL;DR: This paper obtains the optimal movement strategy among a class of Markovian strategies so as to minimize the data loss rate over all sensor nodes, and explains how such an optimalmovement strategy can be made to work in a distributed fashion. (via Semantic Scholar)

2014 conference paper

A general framework of hybrid graph sampling for complex network analysis

2014 proceedings ieee infocom, 2795–2803.

By: X. Xu n, C. Lee n & D. Eun n

TL;DR: A hybrid graph sampling framework is developed that inherits the benefit of returning immediate samples from random walk-based crawling, while incorporating the advantage of reducing the correlation in the obtained samples fromrandom jump, to strike the right balance between random jump and crawling.

Characterizing link connectivity for opportunistic mobile networking: Does mobility suffice?

2013 proceedings ieee infocom, 2076–2084.

By: C. Lee n, J. Kwak n & D. Eun n

TL;DR: This work investigates how each user's availability jointly with mobility-induced contact/inter-contact process affects the link-level connectivity depending on their relative operating time scales and suggests the presence of many uncharted research territories for further exploration.

2013 journal article

On the Forwarding Performance under Heterogeneous Contact Dynamics in Mobile Opportunistic Networks

IEEE TRANSACTIONS ON MOBILE COMPUTING, 12(6), 1107–1119.

By: C. Lee n & D. Eun n

author keywords: Mobile opportunistic networks; heterogeneous contact dynamics; non-Poisson contact dynamics; forwarding performance; stochastic/convex ordering relationships
TL;DR: This paper considers two representative heterogeneous network models, each of which captures heterogeneity among node pairs and heterogeneity in underlying environment (spatial), respectively, and demonstrates that the heterogeneity in mobile nodes' contact dynamics should be properly taken into account for the performance evaluation of forwarding algorithms.

Smart sleep: sleep more to reduce delay in duty-cycled wireless sensor networks

2011 proceedings ieee infocom, 611–615.

By: C. Lee n & D. Eun n

TL;DR: This paper proposes a simple modification of random duty cycling, named Smart Sleep, which achieves more power-saving as well as faster packet diffusion (or smaller delay) while retaining the benefits of SRW. (via Semantic Scholar)

A Distributed Wake-up Scheduling for Opportunistic Forwarding in Wireless Sensor Networks

2010 ieee global telecommunications conference globecom 2010.

By: C. Lee n & D. Eun n

TL;DR: It is proved that the proposed algorithm outperforms pure homogeneous duty cycling, where every node uses the same wake-up rate, in its guaranteed asymptotic upper bound of the worst-case delay for \emph{any} graph. (via Semantic Scholar)
