CenWits: A Sensor-Based Loosely Coupled Search and Rescue System Using Witnesses
PhD Candidate
This paper describes the design, implementation and evaluation of a search and
rescue system called CenWits. CenWits uses several small, commonly-available
RF-based sensors, and a small number of storage and processing devices. It is
designed for search and rescue of people in emergency situations in wilderness
areas. A key feature of CenWits is that it does not require a continuously
connected sensor network for its operation. It is designed for an
intermittently connected network that provides only occasional connectivity.
It makes a judicious use of the combined storage capability of sensors to
filter, organize and store important information, combined battery power of
sensors to ensure that the system remains operational for longer time periods,
and intermittent network connectivity to propagate information to a processing
center. A prototype of CenWits has been implemented using Berkeley Mica2 motes.
The paper describes this implementation and reports on the performance measured
from it.
This paper is to be presented in The 3rd ACM Conference on Embedded Networked Sensor Systems (SenSys) 2005.

BACTAC, the Beverage And Chips Tuesday Afternoon Colloquium, is a weekly forum
run by graduate students. The goal is provide an informal setting in which
anyone can (basically) present anything. In the past, we have had practice
talks for conferences and job interviews, research reports, juggle lessons (!),
student representative reports, internship discussions, an introduction to
ergonomics, and "pay attention to this when you are going to look for job"
discussions.
BACTAC is meant to be an informal and social event to promote the interaction
among graduate students. BACTAC is typically held every Tuesday, at 3:30pm,
in room ECOT 831. Free munchies and drinks are provided.
