Despite over a decade of research in multi-hop ad-hoc networks, a fundamental performance limitation remains largely unsolved. Significant performance problems occur when transmissions are hopped over multiple wireless nodes utilizing the same frequency. Although this is a contention problem, it is exacerbated by numerous other ad-hoc specific issues. The solution, which has been attempted at many layers in the ISO networking model, is to turn multi-hop ad-hoc networks from single channel networks into multi channel networks. RDCS (Routing Driven Channel Selection) is a channel selection mechanism that operates with the OLSR (Optimized Link-State Routing) protocol. It circumvents multihop performance problems by enabling multi-radio 802.11 mesh nodes to intelligently utilize a range of frequencies.
