Workshop Location: University of Washington A two-day workshop on Localization
in Wireless Sensor Networks: Estimation, Security and Robustness is being organized under the sponsorship of Army Research Office
(ARO). It will take
place June 13-14, 2005 at the University of Washington, Seattle and is hosted by the
Department
of Electrical Engineering. Workshop Objective: The workshop in intended to bring together a panel of experts to present state of art research in the area of wireless sensor localization, and to discuss roadmap for future research and priorities for research investment of ARO. Localization is a critical process in
mobile ad hoc networks that will be forming dynamic coalitions for critical
missions of the future armed forces. Since the mobile soldiers will be
equipped with multiple sensors that will provide location based data, it
becomes significantly important that each sensor node knows its location or
its relative location with respect to the rest of the coalition members.
However, due to wireless communication, the dynamic coalition is highly
vulnerable to attacks and the relative localization process itself is
vulnerable. Hence, one must develop robust techniques that provide accurate
position estimates even in the presence of attackers. The localization in
the urban area as well as the caves and forest is known to be hard due to
the lack of GPS information, and is its infancy at this point. Hence, the
problem of secure localization must jointly consider the estimation accuracy
as well as the robustness against attacks. Further more, due to the
untrustworthy nature of the environment, providing mechanisms such as key
management for secure localization become important. Hence, security,
robustness and accuracy are three systemic parameters that must be achieved.
Apart from these, due to the resource-constrained nature of the sensor
devices, the solutions to be obtained must also be resource-efficient. In
the case of sensor, the battery power becomes one of the critical resources
that need to be conserved and optimized. The battery power is expended by
communication and computing operations performed by a sensor node. Studies
have shown that the computing in general can be optimized while the
communication cost is a function of the physical medium. Hence, in order to
develop energy-efficient solutions, the physical layer information must be
jointly considered with the application layer operations, thus requiring a
cross-layer approach towards this problem. Such much needed solution
approaches do not exist in the current literature. ARO and Army in general
will benefit greatly from the research and understanding in this area. The presentations of the attendees are supposed to be tutorial in
nature including (but not limited to) the following items: 1. Area and problem background 2. Existing
results in the area 3. On-going
research and problems 4. Critical
challenges that were ignored in past work 5. Future
challenges and why they are important 6. New
tools need for addressing future challenges
