Power Bargaining in Multi-Source Relay Networks

In this paper, the authors consider a multi-source single-relay wireless network, where the relay facilitates transmissions of the sources' signals to the destination. They study the relay power allocation among the sources, and use the bargaining theory to model the negotiation among the sources on fair allocation of the relay power. By assigning a bargaining power to each source to indicate its transmission priority, they propose an asymmetric Nash Bargaining Solution (NBS)-based relay power allocation scheme. The impact of the bargaining powers on the relay power allocation and network performance is analyzed.
