Title: "DIAGNOSIS IN WIRELESS SENSOR NETWORK"

Abstract

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 nodes 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.
