Energy-efficient infrastructure sharing in multi-operator mobile networks

PROJECT TITLE :

Energy-efficient infrastructure sharing in multi-operator mobile networks

ABSTRACT:

Network infrastructure sharing and base station switching off mechanisms are recently introduced as promising solutions toward energy and price reduction in cellular networks. Although these techniques are typically studied independently, their combination offers new alternatives to MNOs for serving their users and may potentially give them with additional benefits. In this text we tend to introduce the concept of intra-cell roaming-based infrastructure sharing, where the MNOs may switch off their BSs and roam their traffic to active BSs operated by other MNOs in the same cell. Motivated by the coexistence of multiple operators in the same area, we have a tendency to present possible network deployments and architectures in current and future cellular eventualities, discussing their specific characteristics. Additionally, we tend to propose an innovative distributed game theoretic BS switching off theme, using an integrated value function that takes into account all the various cases for a given operator to serve its own traffic (i.e. through active BSs of neighboring cells or exploiting intra-cell roaming-primarily based infrastructure sharing). Finally, we demonstrate some indicative simulation ends up in realistic scenarios to quantify the potential energy and money edges that our proposed theme offers to the MNOs in multioperator environments, providing them with the mandatory incentives to participate within the infrastructure sharing.
