In my thesis, I analyze the reliability of energy-efficient networks. Nowadays, it is expected, that the communication networks become environmentally aware. In these systems, the environmental impact is mostly rated by the energy consumption, and many green solutions suggest to turn off some network equipments. This is possible due to the latest technologies, because they allow the items to temporary shutdown.

The effectiveness of these solutions has been addressed in a number of studies, mostly from the QoS and consumption point of view. In addition to the expected quality of service, network reliability is an important issue in the development as well. In my thesis I study two energy-efficient network design methods, that operate under green engineering methods.

I compare the methods with a not energy efficient design method, and examine the differences from the reliability’s point of view. The study includes both systematically structured and random topology networks. The study analyzes the recovered and the unprotected networking scheme. Based on the results the different design methods can be compare by cost and energy consumption metrics.
