摘要: Due to environmental concerns and strict constraints on interference imposed other networks, the radiated power of emerging pervasive wireless networks needs be strictly limited, yet without sacrificing acceptable data rates. Pulsed Time-Hopping Ultra-Wide Band (TH-UWB) is a radio technology that has potential satisfy this requirement. Although TH-UWB multi-user technology, non-zero cross-correlation between time-hopping sequences, time-asynchronicity sources multipath channel environment make it sensitive strong interferers near-far scenarios. While most protocols manage multiple-access through control or mutual exclusion (CSMA/CA TDMA), we base our design rate control, relatively unexplored dimension for management. We further take advantage nature pulsed propose an mitigation scheme reduces impact interferers. A source always allowed send continuously adapts its code (hence rate) experienced at destination. In contrast exclusion, MAC layer local sender receiver does not need coordination among neighbors involved in transmission. show by simulation achieve significant increase network throughput.
