Wireless Sensor Networks"

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 low duty cycle WSN nowadays, however, are far restricted by the 
limited understanding and the underachieved design of the forwarding 
mechanisms. This dissertation is based on real-world WSN measurements and 
mainly addresses three key issues that emerge from real applications, namely 
bursty-loss aware lazy forwarding, duplicate detectable opportunistic 
forwarding and end-to-end delay measurement, modeling and optimization. We 
develop theoretical principles and practical approaches to address the above 
issues. Through extensive real-world implementations and trace-driven 
experiments, we evaluate those proposed methods and verify the efficiency.
