A radio channel model for D2D communications blocked by single trees in forest environments
In this paper we consider the D2D (Device-to-Device) communication taking place between Wireless Sensor Networks (WSN) elements operating in vegetation environments in order to achieve the radio channel characterization ... -
Radio wave propagation and WSN deployment in complex utility tunnel environments
The significant growth of wireless communications systems in the last years has led to the adoption of a wide range of applications not only for the general public but, also, including utilities and administrative authorities. ... -
Random subwavelength structures on glass to improve photovoltaic module performance
Glass samples have been processed by a single-step self-masking RIE (Reactive Ion Etching) process to obtain random subwavelength structures (SWSs), which mimic anti-reflective and anti-soiling patterns present in nature. ... -
Ransomware early detection by the analysis of file sharing traffic
Crypto ransomware is a type of malware that locks access to user files by encrypting them and demands a ransom in order to obtain the decryption key. This type of malware has become a serious threat for most enterprises. ... -
Real time measuring system of multiple chemical parameters using microstructured optical fibers based sensors
In this paper, a multiplexing system for simultaneous interrogation of optical fiber sensors which measure different parameters is presented and validated. The whole system has been tested with 6 different sensing heads ... -
