This book examines the handoff problem of cellular networks in Part I
and the Power management problem of sensor networks in Part II. Both
problems are key issues in resource allocation and in ensuring quality
of service in the respective applications of wireless networks. Handoff
from one serving base station to another occurs when certain conditions
on signal quality at serving base station are not met. Power management
in sensor networks ensures that sensors last longer, and therefore the
required quality of information collected from sensors is achieved. Part
I will show the inadequacy of existing criteria for comparing handoff
methods considering many factors that influence quality, and develop a
realistic and comprehensive criterion to do so. Part II focuses on
developing a comprehensive energy model for sensors and their use to
enable new strategies for power management in sensor networks. The work
provides guidelines for efficient and reliable sensor network design
that can be used to optimize energy efficiency subject to required
specifications. It proposes High Powered Cluster Heads to increase the
sensor network lifetime.
