Abstract

Wireless technologies grow rapidly and benefit almost every aspect of our daily 
lives. The assignments of wireless channels, which are known as the most 
precious resources in wireless networks, causes intensive research interests 
from both academic and industrial fields.

This dissertation research focuses on designing practical and efficient channel 
assignment algorithms in various newly emerging wireless networks. I have 
worked for several key issues related to the field of wireless sensor networks 
(WSNs) and that of cognitive radio networks (CRNs), including the fair channel 
assignment problem in WSNs aiming to achieve fairness and throughput 
simultaneously, the boundary detection problem in a CRN using dedicated WSSNs 
for spectrum sensing, and the sensing channel assignment problem in CRN under 
the scenario where multiple primary users exist. I conduct comprehensive 
experiments to reveal the fundamental features of the channel availabilities. I 
also develop theoretical model to analyze the behaviors of the networks and 
design practical protocols to enable the effectiveness and efficiency of the 
network communications. The proposed approaches can be further replanted to 
other application areas where WSNs and CRNs are utilized.
