Inhalt:
Recently, direct device-to-device (D2D) communication has gained broad attention. This paper studies a distributed model for the assignment of transmitter-receiver links to frequency resources within a D2D network. We present a novel and low-complex protocol based on the game-theoretic framework of stable many-to-many matching. In this model, several links can share the same resource and each link can use several resources for communication. In order to promote fairness in the system, the resource assignment is restricted through matching quotas. Although spectral reuse is allowed, we ensure reliable transmissions on every resource by an appropriate power allocation scheme based on conservative interference assumptions. The power allocation of each device takes SINR goals into consideration while incorporating an energy-efficient use of the resources. Simulation results evaluate the performance of our distributed algorithm against a centralized resource allocation scheme.
