چکیده
Wireless networks in agricultural environments are unique many ways. Recent measurements reveal that the dynamics of crop growth impact wireless propagation channels with a long-term seasonal pattern. Additionally, short-term environmental factors, such as strong wind, result variations channel statistics. Next-generation fields, populated by autonomous tractors, drones, and high-throughput sensing systems, require connectivity infrastructure, resulting future deployment high-frequency networks, where they have not been deployed before. More specifically, when millimeter-wave (mmWave) communication viable candidate for 5G 6G solutions, higher throughput, these issues become more prominent due to relatively small wavelength at this frequency band. To improve coverage mmWave spectrum settings, reconfigurable intelligent surfaces (RISs) promising solution low energy consumption high cost efficiency compared half-duplex active relays multiple antennas. ensure link resiliency under dynamic behavior, an adaptive RIS broadband (AgRIS) band is designed work. AgRIS relies on output from time-series model forecasts wind speed based measured data, which readily available most farms. The temporal correlation between reliability demonstrated through extensive field experiments. Our simulation results demonstrate footprint 11 × elements can help mitigate adversarial effects wind-induced signal level drop up 8 dB provides 1 Gbits/joule.

متن کاملAn Adaptive LEACH-based Clustering Algorithm for Wireless Sensor Networks
LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...
متن کاملWideband Millimeter - Wave Cavity - Backed Bowtie Antenna
Although many directive antennas operating in a narrow band of millimeter (mm) waves were reported, e.g., antennas for 60GHz wireless local area network (WLAN), their wideband counterparts are still unpopular. Cavity-backed antennas (CBAs) are widely developed and reported in microwave frequency bands, but handful of literatures can be found about mm-wave CBAs in spite that their many propertie...
