Energy efficiency is one of the most important guidelines for nowadays cellular mobile networks development since half of the operating costs of the providers come from the energy bill. Almost 80% of the power is consumed at the base stations. Although current mobile systems produce only 1-2% of the world's carbon footprint but the rapid development, the rising bandwidth demand makes it essential for the new devices and network elements to work more effectively in terms of energy consumption.

One major way to reduce the energy consumption of the mobile cellular networks is cooperation between mobile network providers of the same geographical area. There were some research activities in this topic and a well-defined switch-off method has been proposed. The solution is proven to be optimal in maximizing the overall savings of the cooperating providers. While emission and operators costs are minimized applying this solution, fair reallocation of costs/savings between the cooperating providers has not been investigated so far.

In my thesis the main objective is to introduce a novel solution how to redistribute the total costs/savings between the cooperating providers according to Game Theoretical notions. The performance of the examined game theoretic solutions was compared with the optimal case, showing how fairness is introduced and how the costs and savings for the involved entities are varying according to the novel solutions used.
