“…For thorough observation, the time duration for data collection should be conducted for 24 hours for more accurate results. In addition, the use various antenna, observation on several sites and the consideration of the temperature variation for the different season could be studied because there may be other parameters that can affect the weather such as the wind, rain, humidity and many more [15]- [20].…”

In tropospheric layer, radio waves can propagate in a number of different physical mechanisms such as free-space propagation or line-of-sight propagation, reflection, transmission, diffraction, scattering and wave guiding. The constituents in weather such as the wind, air temperature and atmospheric water content may combine in many ways. Certain combinations can cause radio signals to be heard hundreds of miles beyond the ordinary range of radio communications. This study investigates the effect of weather (temperature) on radio wave propagation up to 9GHz. Continuous-wave (CW) envelope fading waveforms were recorded over a period of the one-hour using patch antenna. The observations were conducted at KUSZA Observatory, East Coast Environmental Research Institute (ESERI), UniSZA which is situated in Merang, Terengganu. Spectrum Analyser was used for RFI measurement and weather station for weather effect. The graphs of radio signal attenuation for weather parameter (temperature) against time were plotted. The findings indicate that there is a relationship between radio signals with the change of temperature. The correlation between RFI frequencies and temperature give negative effect for frequency 945 MHz, was r = -0.085, while for 383 MHz (r = 0.249), 1800 MHz (r = 0.268) and 2160 MHz (r = 0.134). These findings will benefit radio wave propagation research field which includes radio astronomy observations, space science, wireless communication, satellite, antenna and mobile communication and also electromagnetic radiation (EMR) research for health.Keywords-temperature effect, radio signal propagation, radio astronomy, radio frequency interference.

There has been a significant increase in the proliferation and implementation of Wireless Sensor Networks (WSNs) in different disciplines, including the monitoring of maritime environments, healthcare systems, and industrial sectors. It has now become critical to address the security issues of data communication while considering sensor node constraints. There are many proposed schemes, including the scheme being proposed in this paper, to ensure that there is a high level of security in WSNs. This paper presents a symmetric security scheme for a maritime coastal environment monitoring WSN. The scheme provides security for travelling packets via individually encrypted links between authenticated neighbors, thus avoiding a reiteration of a global rekeying process. Furthermore, this scheme proposes a dynamic update key based on a trusted node configuration, called a leader node, which works as a trusted third party. The technique has been implemented in real time on a Waspmote test bed sensor platform and the results from both field testing and indoor bench testing environments are discussed in this paper.

“…On the other hand, Wireless Sensor Networks (WSN) integrate functions of sensing, computation and communication to monitor a wide range of environmental parameters. In [1] authors study the effect of temperature and humidity on radio signal strength in outdoor WSNs. Experimental measurements were performed using Atmel ZigBit 2.4 GHz wireless modules, both in summer and wintertime and testing over all the channels specified by IEEE 802.15.4 for 2.4 GHz ISM frequency band with two power levels.…”

“…Specific weather conditions (e.g., heavy rain fall, extreme winds, fog) can lead to partial degradation of network performance characteristics, e.g., the capacity of wireless links can decrease significantly due to signal attenuation in the presence of heavy rain [1]. On a larger scale, other more-impacting weather condition (e.g.,weather-based disasters as hurricanes, or tornadoes) can cause very extensive network disruptions (consider, e.g., the extent of damage caused by the hurricane Katrina in New Orleans in 2005 [2]).…”

Abstract-Due to the increasing dependence on network services of our society, research has recently been concentrating on enhancing traditional protection strategies to withstand largescale failures, as in case of disaster events. The recently-formed EU-funded RECODIS project aims at coordinating and fostering research collaboration in Europe on disaster resiliency in communication networks. In particular, the Working Group (WG) 2 of the RECODIS project focuses on developing new networkresiliency strategies to survive weather-based disruptions. As a first step, WG2 members have conducted a comprehensive literature survey on existing studies on this topic. This paper classifies and summarizes the most relevant studies collected by WG2 members in this first phase of the project. While the majority of studies regarding weather-based disruptions deals with wireless network (as wireless channel is directly affected by weather conditions), in this survey we cover also disasterresiliency approaches designed for wired network if they leverage network reconfiguration based on disaster "alerts", considering that many weather-based disruptions grant an "alert" thanks to weather forecast.
