Dedication

This thesis is dedicated to my father, who taught me that the best kind of knowledge to
have is that which is learned for its own sake. It is also dedicated to my mother, who
taught me that even the largest task can be accomplished if it is done one step at a time.
To my brothers and lovely sister, and to all friends who they supported me till finish this
work. I lovingly dedicate this thesis to my wife, who supported me each step of the way.

Acknowledgment
I would like to specially thank my supervisor Dr. Hussein Al-Bahadili, who taught me
everything that I know about research and the way it should be done. I would like to
thank him for his guidance during all stages of this research, for answering endless
questions, for his great support, professional advice, and profound understanding.
Through this work, Dr. Hussein has shown me how to attack a problem from different
angels, how to approach it, and how to find the most suitable solution.
I also would like to thank all members of staff at Middle East University, in particular,
the members of staff at the Graduate College of Computing Studies.
Finally, it would be unthinkable of me not to thank my parents, wife, children, brothers
and friends for their support and encouragement over the years. I am thankful for anyone
who supported me during my master study.
