摘要

Through an intensive measurement campaign, this paper investigates propagation loss on snow covered terrain for near ground Wireless Sensor Networks (WSNs). Here, we measure near ground path-loss and shadowing effects in a dense forest accumulated with snow of 60cm thickness at 2.45 GHz center frequency. These effects were studied by placing antennas at three different heights: 0 cm (buried inside the snow and on ground surface), 35 cm (partially buried in the snow), and 60 cm (located on the top of snow surface). Measurements were repeated for line-of-sight (LOS) and non-LOS (NLOS) scenarios.
