Title: "Diagnosis in Wireless Sensor Networks"

by

Mr. Qiang MA


ABSTRACT:

In general, wireless sensor networks are used to fetch information on
spatio-temporal characteristics of the observed physical world,
spawning numerous unforeseen applications. Due to the special nature
of the deployment environment and sensor node’s intrinsic instability,
network failure happens unpredictably. Besides, a number of
applications, such as ecological habitat monitoring and accident
detection, inherently rely on persistent and instantaneous sensing
data. Therefore, network diagnosis, a process of deducing the exact
root cause of a failure from a set of observed failure indications,
becomes of great importance in the development of wireless sensor
networks.

Based on two real world environment monitoring sensor network projects
GreenOrbs and CitySee, this proposal addresses three key aspects for
network diagnosis and management, i.e., evidence collection, faulty
link detection and network bottleneck detection. Through testbed
evaluation, intensive simulations and real world implementations, I
evaluate the performance of the proposed approaches and verify the
applicability. Some of them are also applied to our system management
tools for large-scale wireless sensor networks.
