The last century can be identified with the transformation of mankind due to the large-scale adoption of technology. Significant changes have taken place in the planet due to continual outcomes from research. These technological advances have resulted in considerable changes in the overall quality as well as expectancy of human life. While technology has generally resulted in positive effects on the human civilization, such unplanned changes can also have numerous associated unexpected and emergent outcomes. In this book, we present first steps and results of research conducted in this direction. Specifically, we present algorithms and techniques for the solution of two common problems faced in computer networks in general and data-centric networks, in particular. The intended goal is to develop reusable methods which may be helpful in developing greener networks.
