Reliable data delivery in large-scale low-power sensor networks
Daniele Puccinelli, Martin Haenggi
Article No.: 28
In data collection applications of low-end sensor networks, a major challenge is ensuring reliability without a significant goodput degradation. Short hops over high-quality links minimize per-hop transmissions, but long routes may cause...
Secure and robust virtual coordinate system in wireless sensor networks
Jing Dong, Kurt E. Ackermann, Brett Bavar, Cristina Nita-Rotaru
Article No.: 29
Virtual Coordinate System (VCS)-based routing provides a practical, efficient, and scalable means for point-to-point routing in wireless sensor networks. Several VCS-based routing protocols have been proposed in the last few years, all assuming...
Collaborative location certification for sensor networks
Jie Gao, Radu Sion, Sol Lederer
Article No.: 30
Location information is of essential importance in sensor networks deployed for generating location-specific event reports. When such networks operate in hostile environments, it becomes imperative to guarantee the correctness of event location...
Physiological value-based efficient usable security solutions for body sensor networks
Krishna K. Venkatasubramanian, Sandeep K. S. Gupta
Article No.: 31
A Body Sensor Network (BSN) is a network of economically powered, wireless, wearable, and implanted health monitoring sensors, designed to continually collect and communicate health information from the host they are deployed on. Due to the...
Distributed energy-efficient target tracking with binary sensor networks
Zijian Wang, Eyuphan Bulut, Boleslaw K. Szymanski
Article No.: 32
Target tracking is a typical and important cooperative sensing application of wireless sensor networks. We study it in its most basic form, assuming a binary sensing model in which each sensor returns only 1-bit information regarding target's...
Asymptotic distortion exponents for the estimation of time-varying channels in multihop sensor networks
Satish Vedantam, Urbashi Mitra, Ashutosh Sabharwal
Article No.: 33
The problem of time-varying channel estimation in multihop sensor networks is examined. Two relay processing methods are explored: amplify-and-forward and encode-and-forward. Bounds on the end-to-end distortion for all internode channel estimates...
The Tenet architecture for tiered sensor networks
Jeongyeup Paek, Ben Greenstein, Omprakash Gnawali, Ki-Young Jang, August Joki, Marcos Vieira, John Hicks, Deborah Estrin, Ramesh Govindan, Eddie Kohler
Article No.: 34
Most sensor network research and software design has been guided by an architectural principle that permits multinode data fusion on small-form-factor, resource-poor nodes, or motes. While we were among the earliest promoters of this...
An as-rigid-as-possible approach to sensor network localization
Lei Zhang, Ligang Liu, Craig Gotsman, Steven J. Gortler
Article No.: 35
We present a novel approach to localization of sensors in a network given a subset of noisy inter-sensor distances. The algorithm is based on “stitching” together local structures by solving an optimization problem requiring the...
When a sensor network is deployed, it is typically required to support multiple simultaneous missions. Schemes that assign sensing resources to missions thus become necessary. In this article, we formally define the sensor-mission assignment...
