Multipath fading in wireless sensor networks: measurements and interpretation

摘要: Multipath fading heavily contributes to the unreliability of wireless links, causing fairly large deviations from link quality predictions based on path loss models; its impact sensor networks is considerable. Although analytical models provide a probabilistic description, multipath deterministic phenomenon. Moreover, in case static nodes, time-invariant. We illustrate spatial nature with experimental evidence obtained using lower-end sensing node hardware. also show limitations supposed immunity wideband radios indoor deployments.
