Abstract Current industries leave a big ecological footprint that needs to be reduced to preserve our resources. For it, big industries are leading new researches to move to more environmental-friendly technologies. In this paper we explain an innovative technology which has the ability to introduce edge-computing in the node in combination with energy harvesting, which allows the device to work without the need of batteries. Also, as all the computations are performed in the node, it allows the use of long-range communication protocols. To demonstrate the behavior of the technology, the paper also presents two cases of use in facilities.

Abstract: The basic idea of this project is to save the life of fishermen at sea. We do this by installing a module in the fisherman’s life jacket. This module will be a transmitter which can transmit its current location. This module is made to be a floating module. Which is also waterproof. The person in the dangerous situation can press the button and the transmitter starts transmitting the location. The data is then transferred to the receiver via a network built by WLAN module which is also made by us. The WLAN module consists of the transmitter and the receiver and acts as repeater stations. These transmitters and receivers also contain the LoRa module. The LoRa module is Incorporated because of its long range communication specifications. The repeater station is placed buoy the help of buoys. Buoys are floating objects which are then anchored to make them stationary. The receiver is a portable one and dynamically we can get the location of the transmitter. Hence we can locate the person and then rescue them Keywords: LoRa, WLAN, GPS module,

AbstractThe acoustic adaptation hypothesis (AAH) predicts that vocalizations intended for unambiguous long range communication should possess amplitude modulation (AM) characteristics such that the temporal patterning of amplitude degrades less than alternative patterns during transmission through native habitat. The specific predictions are that open habitat signals should be structured as rapid AM trills, whereas closed habitat signals should be structured as low-rate AM tonal whistles. To investigate the benefit of trill- and whistle-structured signals in open and closed habitats, respectively, a high and low carrier frequency set of four synthetic signals which ranged from rapid AM trills to low rate AM whistles were transmitted 3 hours after sunrise through five different habitat types ranging from closed mature forest to open grassland. Results indicate that, on average, whistles degrade less than trills in both habitats. Trills benefit in open habitats through their tendency to be received with a more consistent quality than whistles. Such differences in transmission consistency among AM patterns are not found in closed habitats. While not degrading less on average, lower frequency signals are received with a more consistent quality than are higher frequency signals of the same AM structure, in both open and closed habitats.
