Flooding in wireless ad hoc networks
Hyuk Lim,Chong-kwon Kim +1 more
TL;DR: It is shown that the minimum cost flooding tree problem is similar to MCDS (Minimum Connected Dominating Set) problem and it is proved that the NP-completeness of the minimumCost Flooding tree problem can be proved.
Proceedings ArticleDOI
Zero-Configuration, Robust Indoor Localization: Theory and Experimentation
TL;DR: A localization algorithm for building a zero- configuration and robust indoor localization and tracking system to support location-based network services and management and is quite robust and gives accurate localization results (i.e., with the localization error within 3 meters).
Proceedings ArticleDOI
Improving spatial reuse through tuning transmit power, carrier sense threshold, and data rate in multihop wireless networks
TL;DR: This paper studies spatial reuse in wireless ad-hoc networks and proposes a decentralized power and rate control algorithm to enable each node to adjust, based on its signal interference level, its transmit power and data rate, which yields higher network capacity.
Journal ArticleDOI
J-Sim: a simulation and emulation environment for wireless sensor networks
Ahmed Sobeih,Jennifer C. Hou,Lu-Chuan Kung,Ning Li,Honghai Zhang,Wei-Peng Chen,Hung-Ying Tyan,Hyuk Lim +7 more
TL;DR: A modeling, simulation, and emulation framework for WSNs in J-Sim - an open source, component-based compositional network simulation environment developed entirely in Java that provides an object-oriented definition of target, sensor, and sink nodes, sensor and wireless communication channels, and physical media such as seismic channels, mobility models, and power models.
Journal ArticleDOI
Coordinating transmit power and carrier phase for wireless networks with multi-packet reception capability
TL;DR: This article proposes a feedback-based transmit power and carrier phase adjustment scheme that estimates the symbol energy and the carrier phase offset for each transmitter’s received signal, computes the optimal received power levels, and feeds the optimal transmit power level and phase shift information back to the transmitters.
