Title: "Measurement and Design on Data Collection of Low-Duty Cycle Wireless 
Sensor Networks"

by

Mr. Zhichao Cao


ABSTRACT:

Wireless sensor networks (WSN), which consist of numerous 
energy-constrained sensor nodes, are mostly duty-cycled and rely on 
multi-hop routing to collect data. Data collection mechanism is thus a 
building block of WSN systems. The performance of WSNs nowadays, however, 
are far restricted by the limited understanding and the underachieved 
design of data collection mechanisms. This proposal is based on real-world 
WSN measurements and mainly addresses two key issues that emerge from real 
applications, namely bursty-loss aware lazy forwarding, and end-to-end 
delay measurement, modeling and optimization. I develop theoretical 
principles and practical approaches to address the above issues. Through 
extensive real-world implementations and trace-driven experiments, I 
evaluate those proposed methods and verify the efficiency. As the future 
work towards my dissertation, this proposal also includes the research 
plan concerning the impact of network dynamics, such as link dynamics and 
down-stream routing changes, to avoid the potential risk.
