Fundamental Concepts for Information Gathering in Sensor Networks
Description:
Wireless networks of sensors will be widely deployed in the future because they
greatly extend our ability to monitor and control the physical environment from
remote locations. One of the most important communication primitives that has
to be provided by sensor networks is information gathering: information from
the sensors has to be forwarded to a single point for evaluation. Since sensors
will exist with the ratio of (hundreds of) thousands of nodes per user, it is
impossible to pay attention to any individual node. Hence, it is important to
use communication methods in sensor networks that are extremely simple --
to allow a verification of their correct implementation -- and
self-reconfiguring -- to allow automatic adjustments to changes in the sensor
network or sensing tasks. Furthermore, since sensors are simple devices with
limited processing power, storage capacity, and energy, it is important to
develop routing strategies that can support information gathering as
efficiently as possible. Whereas many heuristics have already been suggested
for resource-efficient information gathering in sensor networks, almost no
rigorous theoretical work has been performed in this area yet.
Therefore, the goal of this project is to explore fundamental concepts
for self-reconfigurable and resource-efficient information
gathering in wireless sensor networks.
