As wireless networks evolve, the spatial reuse becomes important because it heavily affects overall network throughput. Especially in a dense network, the selection of transmission nodes highly influences the number of simultaneous transmissions. In this paper, we propose a spatial reuse enhanced medium access control (SRE MAC) that gives transmission priority to the nodes that have a small number of interferers. Both centralized and distributed approaches are considered with a hierarchical network model. The performance comparison shows that, with a perfect MAC control, the proposed SRE MAC enhances the network-wide throughput through allowing more number of transmissions in parallel.
