“…This, however, under represents the complexity of the propagation channel. The low transmission power characteristic of WSN devices means that most of the envisaged applications are in areas where line of sight (LOS) path between the transmitter and receiver exist [21].…”

Abstract-This paper presents results of a study to characterise wireless point-to-point channel for wireless sensor networks applications in sport hard court arenas, grass fields and on roads. Antenna height and orientation effects on coverage are also studied and results show that for omni-directional patch antenna, node range is reduced by a factor of 2 when the antenna orientation is changed from vertical to horizontal. The maximum range for a wireless node on a hard court sport arena has been determined to be 70 m for 0 dBm transmission but this reduces to 60 m on a road surface and to 50 m on a grass field. For horizontal antenna orientation the range on the road is longer than on the sport court which shows that scattered signal components from the rougher road surface combine to extend the communication range. The channels investigated showed that packet error ratio (PER) is dominated by large-scale, rather than small-scale, channel fading with an abrupt transition from low PER to 100% PER. Results also show that large-scale received signal power can be modeled with a 2nd order log-distance polynomial equation on the sport court and road, but a 1st order model is sufficient for the grass field. Small-scale signal variations have been found to have a Rice distribution for signal to noise ratio levels greater than 10 dB but the Rice K-factor exhibits

“…The RF receiver sensitivity is rated at −94 dBm [34], however measurements by the authors showed that the receiver sensitivity is −90 dBm. The MRF24J40MA transceiver's micro-strip omnidirectional antenna has an E-shape as shown in Figure 1(c) [21,34].…”

In order to realize the deployment of wireless sensor network in large areas of plastic greenhouses. The propagation characteristics of radio wave in plastic greenhouse were studied. The Received Signal Strength Index(RSSI)in greenhouse and between greenhouses were studied, and the logarithmic path loss model for RSSI was established. The results show that the radio wave attenuation parameters A and n between greenhouses were 30.785 and 2.89. The attenuation index was larger than the index of free space. In the plastic greenhouse planted with tomatoes, the radio wave attenuation parameters A and n in the ground were 34.99 and 3.64, and in the top of canopy were 35.14 and 2.85, its show that the radio wave transmission has been significantly affected by the crop in the plastic greenhouse.

“…In [ 12 ], a measurement campaign at 433 MHz in indoor scenarios (parking plenty of cars) is carried out in order to characterize the path-loss with the distance for WSN in this frequency-band. Finally, in [ 13 ], an outdoor measurements campaign at 5.8 GHz for the statistical characterization of the propagation in a Durian Orchard forest is presented. In this paper, we present the results of a field measurement campaign that has been carried out to characterize the propagation and the performance behavior (considering distance, height, payload size, obstacles and interference) of one of the most utilized WSN platforms, the MICAz platform from Crossbow [ 14 ], which works in the 2.4 GHz.…”

Frequently, Wireless Sensor Networks (WSN) are designed focusing on applications and omitting transmission problems in these wireless networks. In this paper, we present a measurement campaign that has been carried out using one of the most commonly used WSN platforms, the micaZ from Crossbow©. Based on these measurements, some guidelines to deploy a robust and reliable WSN are provided. The results are focused on security and environmental applications but can also be extrapolated to other scenarios. A main conclusion that can be extracted is that, from the transmission point of view, a dense WSN is one of the best choices to overcome many of the transmission problems such as the existence of a transitional region, redundance, forwarding, obstructions or interference with other systems.
