Wireless sensor networks are typically composed of low-cost sensors that are deeply integrated in physical environments. As a result, the sensing performance of a wireless sensor network is inevitably undermined by biases in imperfect sensor...
In recent years, the demand for high-precision tracking systems has significantly increased in the field of Wireless Sensor Network (WSN). A new tracking system based on exploitation of Received Signal Strength Indicator (RSSI) measurements in WSN...
Localization with sparse acoustic sensor network using UAVs as information-seeking data mules
Daniel J. Klein, Sriram Venkateswaran, Jason T. Isaacs, Jerry Burman, Tien Pham, João Hespanha, Upamanyu Madhow
Article No.: 30
We propose and demonstrate a novel architecture for on-the-fly inference while collecting data from sparse sensor networks. In particular, we consider source localization using acoustic sensors dispersed over a large area, with the individual...
Energy-efficient data dissemination using beamforming in wireless sensor networks
Jing Feng, Yung-Hsiang Lu, Byunghoo Jung, Dimitrios Peroulis, Y. Charlie Hu
Article No.: 31
Energy conservation is essential in Wireless Sensor Networks (WSNs) because of limited energy in nodes' batteries. Collaborative beamforming uses multiple transmitters to form antenna arrays; the electromagnetic waves from these antenna arrays can...
Distributed and compact routing using spatial distributions in wireless sensor networks
Rik Sarkar, Xianjin Zhu, Jie Gao
Article No.: 32
In traditional routing, the routing tables store shortest paths to all other destinations and have size linear in the size of the network, which is not scalable for resource-constrained networks such as wireless sensor networks. In this article we...
Adaptive energy-efficient scheduling for hierarchical wireless sensor networks
Wei Li, Flávia C. Delicato, Albert Y. Zomaya
Article No.: 33
Most Wireless Sensor Network (WSN) applications require distributed signal and collaborative data processing. One of the critical issues for enabling collaborative processing in WSNs is how to schedule tasks in a systematic way, including...
Towards statistically strong source anonymity for sensor networks
Yi Yang, Min Shao, Sencun Zhu, Guohong Cao
Article No.: 34
For sensor networks deployed to monitor and report real events, event source anonymity is an attractive and critical security property, which unfortunately is also very difficult and expensive to achieve. This is not only because adversaries may...
Wireless Sensor Networks (WSNs) are embracing an increasing number of real-time applications subject to strict delay constraints. Utilizing the methodology of potential field in physics, in this article we effectively address the challenges of...
Property management in wireless sensor networks with overcomplete radon bases
Xiaoye Jiang, Mo Li, Yuan Yao, Leonidas Guibas
Article No.: 36
This article presents a scalable algorithm for managing property information about moving objects tracked by a sensor network. Property information is obtained via distributed sensor observations, but will be corrupted when objects mix up with...
