This thesis is concerned with the application of beamformingand multi-user detection in multi-hop networks. At first, centrally optimized, dis-tributed and emergent methods for improving the connectivity usingare proposed, leading to a considerably better connectedness of multi-hop networks.Then, this work contributes by a novel cross-layer approach to MAC layer design. In aconcept called MUD-MAC, it facilitates multi-user detection in multi-hop networks,showing significant throughput improvements over a single-user system. Finally, thecross-layer approach is applied to beamforming.
