Jointly PHY/MAC Capacity for Ultra-wideband Multi-hop Networks

Ultra-wideband (UWB) radio is a fast emerging technology with uniquely attractive features inviting major advances in wireless communications, networking, radar, imaging, and positioning systems. UWB radios offer great flexibility and shows enormous potential in view of future fourth generation (4G) broadband wireless access in dense multipath environments. In this paper jointly PHY and MAC layer lower bound and upper bound throughput capacity of ultra-wideband ad-hoc network has been found under Voronoi tessellation power control using second derivative UWB waveform. These bounds demonstrate that throughput increases with node density (n). In the simulation we take into account The FCC UWB and FCC Waiver grant regulations with bandwidth between (3.6–10.1 GHz) at maximum power spectrum density (PSD) -40dBm/MHz. with this large bandwidth, and power and interference control, we depict the significant of jointly (PHY/MAC) properties on capacity of UWB ad-hoc indoor environment networks.
