Multi-hop networking is considered to be an essential technology for future wireless network architectures. This thesis is concerned with the application of beamforming and multi-user detection in multi-hop networks. At first, centrally optimized, distributed and emergent methods for improving the connectivity using beamforming are 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 a concept called MUD-MAC, it facilitates multi-user detection in multi-hop networks, showing significant throughput improvements over a single-user system. Finally, the cross-layer approach is applied to beamforming. The resulting new MAC protocol, called BeamMAC, shows similar throughput improvements. The work provides an analytical and simulation-based evaluation of the different approaches, and discusses aspects of their implementation in practice.
