NSF-Funded Collaborative Research on Building an Intelligent, Uncertainty-Resilient Detection and Tracking Sensor Network

Posted on by

Overview

Detection, identification, and tracking of CBRNE (Chemical, Biological, Radiological, Nuclear, and Explosive) plumes can be accomplished by combining the modalities of sensor and cyber networks. The sensor network provides information about physical-space activities, e.g., locations and movements of the plume sources. The cyber network provides storage and computational resources to analyze and infer where the plume originated, the trajectory of its movement, and the prediction of its future movement. The challenges in realizing such a sensor cyber network include intelligent sensing (intelligent sensor selection and coverage) and the capability to deal with uncertainties (uncertainty in measurement as well as in modeling). This project proposes to leverage the convergence between the sensor and the cyber networks to achieve these goals. In particular, the plan is to carry out three synergistic research tasks: 1) network formation by sensor selection, placement, and coverage; 2) sensor tasking protocol with temporal/spatial uncertainty management; 3) protocols for reliable sensor-cyber communication supporting the above two tasks. The PIs will prototype the research results and integrate the prototypes for different components to build the sensor cyber network for plume detection, identification and tracking. They will also evaluate the sensor cyber network using various test scenarios in collaboration with Oak Ridge National Lab. If successful, the project will provide technology for building detection and tracking sensor networks that can give great protection to people and the environment against harmful plumes.

CFP: Real-Time Control in a Big Sensor Data Network

Posted on by

Call for Papers

A large number of important real-time applications depend on the analysis of big sensor data interfacing with the real world. These applications include military, medical, manufacturing, transportation, environmental planning, and disaster management systems. Many have been difficult to realize because of the problems involved with inputting big data from sensors directly into automated systems. Real-time control in a big sensor network has a strong impact on many of the previously mentioned applications especially in the context of processing, monitoring, and the immediate followup and detecting of complex events in many of these systems.

The main focus of this special issue will be on the new and existing real-time applications of big data sensor analytics to problems of global importance. This special issue will also become an international forum for researchers to highlight the most recent development and ideas in the field with a special emphasis on real-time applications. Potential topics include, but are not limited to:

  • Real-time analytics applications
  • Real-time visualization
  • Algorithms for map reduce
  • Data streaming
  • Sensor data storage
  • Sensor network mobility and social networks
  • Sensor cloud
  • Programmability tools
  • Security in big data
  • Data aggregation and protocols in large-scale networks
  • Big sensor platforms/architectures for real-time applications
  • Integration between sensor networks and business systems
  • Deployment, data aggregation, and energy optimization network protocols
  • Large-scale data sensor fusion
  • Machine learning on big data

Title: Processing Spatio-Temporal Queries for Uncertain Trajectories
Time: 2pm on June 10, 2013
Space: ECS 212

ABSTRACT: The ( location, time) data capturing the motion of moving objects is subject to uncertainty due to a number of reasons, such as the imprecision of GPS devices and the fact that we cannot record this data for every time-instant. As a consequence of uncertainty the results of continuous queries become probabilistic in nature, i.e., an objects or trajectory is associated with a qualification probability that indicates how likely it is the answer of the query. We discuss first different models for modeling uncertainty of moving objects in free space and on road networks. Next we formalize two of the most popular types of continuous queries, range queries and nearest neighbor (NN) queries, under the free space and road network models. Next , we elaborate on a methodology for processing NN-queries for the sheared cylinders model used to represent time-parameterized motion in free space. We demonstrate that by using the convolution technique from probability theory we can transform the original problem into a much simpler one, where the query trajectory becomes crisp.
