An energy-aware distributed approach for content and network management

We propose a distributed approach in which an Internet Service Provider (ISP) and a Content Provider (CP) cooperate to minimize total power consumption. Our solution is distributed between the ISP and the CP to limit shared information, such as network topology and servers´ load. In particular, we adopt a dual decomposition technique. We investigate the performance of the proposed solution on realistic case-studies.We compare our algorithms with a centralized model, whose aim is to minimize total power consumption. We consider different power models for devices. Results show that the distributed algorithm is close to the optimal solution, with a power efficiency loss less than 17%.
