VigilNet: An integrated sensor network system for energy-efficient surveillance
Tian He, Sudha Krishnamurthy, Liqian Luo, Ting Yan, Lin Gu, Radu Stoleru, Gang Zhou, Qing Cao, Pascal Vicaire, John A. Stankovic, Tarek F. Abdelzaher, Jonathan Hui, Bruce Krogh
This article describes one of the major efforts in the sensor network community to build an integrated sensor network system for surveillance missions. The focus of this effort is to acquire and verify information about enemy capabilities and...
Distributed weighted-multidimensional scaling for node localization in sensor networks
Jose A. Costa, Neal Patwari, Alfred O. Hero, III
Accurate, distributed localization algorithms are needed for a wide variety of wireless sensor network applications. This article introduces a scalable, distributed weighted-multidimensional scaling (dwMDS) algorithm that adaptively emphasizes the...
Survey and benchmark of block ciphers for wireless sensor networks
Yee Wei Law, Jeroen Doumen, Pieter Hartel
Cryptographic algorithms play an important role in the security architecture of wireless sensor networks (WSNs). Choosing the most storage- and energy-efficient block cipher is essential, due to the facts that these networks are meant to operate...
Redundancy and coverage detection in sensor networks
Bogdan Cărbunar, Ananth Grama, Jan Vitek, Octavian Cărbunar
We study the problem of detecting and eliminating redundancy in a sensor network with a view to improving energy efficiency, while preserving the network's coverage. We also examine the impact of redundancy elimination on the related problem of...
Localized topology control for heterogeneous wireless sensor networks
Xiang-Yang Li, Wen-Zhan Song, Yu Wang
This article studies topology control in heterogeneous wireless sensor networks, where different wireless sensors may have different maximum transmission ranges and two nodes can communicate directly with each other if and only if they are within the...
