In this thesis, we provide a cross-layer analysis of the throughput of the dynamic collision reduction (DCR) protocol, a multiple access protocol that requires frame synchronization. At the physical-layer, we develop the optimal neighbor detector for ultra-wide bandwidth (UWB) signaling in a dense multipath environment with delay uncertainty. The detector takes advantage of the inherent multipath diversity associated with UWB signaling. We then develop an effective distributed control policy, derived from a dynamic programming formulation, to increase the throughput of UWB random-access networks in the DCR protocol. Finally, we construct a model for the distribution of nodes in the plane enabling closed-form analysis of two-hop signaling over wireless channels while capturing many of the transmission dependencies between randomly located relaying nodes. Our results demonstrate promising throughput.
