Decentralized control of adaptive sampling in wireless sensor networks
Johnsen Kho, Alex Rogers, Nicholas R. Jennings
Article No.: 19
The efficient allocation of the limited energy resources of a wireless sensor network in a way that maximizes the information value of the data collected is a significant research challenge. Within this context, this article concentrates on...
Efficient and provably secure aggregation of encrypted data in wireless sensor networks
Claude Castelluccia, Aldar C-F. Chan, Einar Mykletun, Gene Tsudik
Article No.: 20
Wireless sensor networks (WSNs) are composed of tiny devices with limited computation and battery capacities. For such resource-constrained devices, data transmission is a very energy-consuming operation. To maximize WSN lifetime, it is essential...
Acoustic sensor network design for position estimation
Volkan Cevher, Lance M. Kaplan
Article No.: 21
In this article, we develop tractable mathematical models and approximate solution algorithms for a class of integer optimization problems with probabilistic and deterministic constraints, with applications to the design of distributed sensor...
Design, implementation, and evaluation of EnviroMic: A storage-centric audio sensor network
Liqian Luo, Qing Cao, Chengdu Huang, Lili Wang, Tarek F. Abdelzaher, John A. Stankovic, Michael Ward
Article No.: 22
This article presents the design, implementation, and evaluation of EnviroMic, a low-cost experimental prototype of a novel distributed acoustic monitoring, storage, and trace retrieval system designed for disconnected operation. Our...
Deployment-aware modeling of node compromise spread in wireless sensor networks using epidemic theory
Pradip De, Yonghe Liu, Sajal K. Das
Article No.: 23
Motivated by recently surfacing viruses that can spread over the air interfaces, in this article, we investigate the potentially disastrous threat of node compromise spreading in wireless sensor networks. We assume such a compromise originating...
Low-complexity coding and source-optimized clustering for large-scale sensor networks
Gerhard Maierbacher, João Barros
Article No.: 24
We consider the distributed source coding problem in which correlated data picked up by scattered sensors has to be encoded separately and transmitted to a common receiver, subject to a rate-distortion constraint. Although near-to-optimal...
Sensor network data fault types
Kevin Ni, Nithya Ramanathan, Mohamed Nabil Hajj Chehade, Laura Balzano, Sheela Nair, Sadaf Zahedi, Eddie Kohler, Greg Pottie, Mark Hansen, Mani Srivastava
Article No.: 25
This tutorial presents a detailed study of sensor faults that occur in deployed sensor networks and a systematic approach to model these faults. We begin by reviewing the fault detection literature for sensor networks. We draw from current...
Optimal placement of distributed sensors against moving targets
Thomas A. Wettergren, Russell Costa
Article No.: 26
This article addresses the problem of deploying a sparse network of sensors for surveillance of moving targets. The sensor networks of interest consist of sensors which perform independent binary detection on a target, and report detections to a...
An interrelational grouping abstraction for heterogeneous sensors
Vasanth Rajamani, Sanem Kabadayi, Christine Julien
Article No.: 27
In wireless sensor network applications, the potential to use cooperation to resolve user queries remains largely untapped. Efficiently answering a user's questions requires identifying the correct set of nodes that can answer the question and...
