Managing Impulsive Interference in Impulse Radio UWB Networks

摘要: Wireless sensor networks are ideally built on low-cost, low-complexity nodes that have a low power consumption to guarantee long network lifetime. These all properties can potentially be achieved with impulse radio ultra-wide band (IR-UWB). In addition, IR-UWB has fine timing resolution resulting in accurate ranging and localization possible. For these reasons, is an extremely interesting physical layer technology for wireless networks. this article, we consider the management of impulsive interference Impulsive due uncoordinated concurrent transmissions. It occurs, instance, when several independent piconets operate close vicinity also present some MAC proposals allow If not properly addressed, severely affect throughput energy network; as such, it already needs taken into account design phase. First, show serious concern Second, techniques at link cope combat such efficiently. Finally, DCC-MAC example interference-aware design.
