In this paper, the authors examine the problem of channel assignment in multi-hop wireless networks in which each node is equipped with multiple transceivers. They summarize various approaches to transceiver channel assignment. Most approaches in the literature seek to assign a channel to each available transceiver. In contrast, they seek to achieve a baseline connected topology that conserves resources, keeping some fraction of the transceivers inactive so as to dynamically react to changing traffic stimuli. They call their scheme Resource-Minimized Channel Assignment (RMCA). They show that RMCA achieves basic network connectivity and low interference, while using fewer resources compared to other protocols, and performs well under varied node density and number of transceivers per node.
