The innovation of the space-time block codes that which applied to wireless networks enhance the performance of communication with respect to bit error rate and the reliability of the link. When a set of geographically distributed relays are cooperated to treat the information that is transmitted from the source and for miles to the destination so the signal that is received at the destination node will be such as space-time block code. This code will be known as distributed space-time block code. In this paper, the aim is to increase the quality of the transmission between the source and destination nodes by using a group of relays, at the relays, a set of orthogonal space-time block codes will be generated, the code is selected from a set of orthogonal codes based on a random number which generated at the relay and destination nodes in the same manner. Also, the relay nodes involved in the communication between the source and destination nodes are selected based on the selected criteria. The results show that the performance of the system is improved at the destination node in terms of bit error rate and data rate. The simulation results show that all the sets of the adopted codes have the same function and can give one performance, by using these codes which are generated randomly give some security to the whole system.

Green communications and their techniques have taken a vast amount of consideration with the significant advance of the new world. In the same way with the improvement and the updates in communication techniques, the researchers are concentrating on their work to attain communication as green as promising. In mobile systems the evaluation of 5G and beyond will increase the power consumption that results in excess emission of CO2. Furthermore, with the high demand of wireless traffic in the near future, green radio technology for upcoming wireless networks shall include an end-to- end energy efficiency investigation of mobile terminals, radio access and core networks, and diverse applications. This paper surveys various modes of green communication technologies also some challenges that slow down the development of this technology with demand for green techniques which help to decrease the emission of co2 that is a risk to environmental and human conditions.

Cloud computing processes vast quantities of data and offers a variety of flexible, secure, on-demand, and cost-effective collaboration options for consumers. Due to the increasing prevalence of hosted services, data security has become an increasingly critical concern. Hadoop, the engine at the heart of cloud computing, causes serious problems for the cloud. Any public, private, or hybrid cloud environment can use this security solution without any hassle (IaaS). Furthermore, it is compatible with the vast majority of Cloud computing's capabilities. Increase cloud security using NTRU encryption. This study made advantage of the (NTRUEncrypt) algorithms residing in Hadoop to speed up the file encryption and decryption processes. If HDFS is engaged in the Map Task, then HDFS will take care of both the encryption and decryption processes. Data on the cloud can be kept private and secure thanks to the proposed protection technique, which makes use of cryptography. Combining the proposed technique with preexisting infrastructure and web-based.

A look at the wind energy prospects in Iraq

DOI https://doi.org/10.1109/ICEMIS56295.2022.9914119

This research provides an overview of Iraq’s renewable energy prospects. One of the most important sorts of renewable energy resources in the world is wind energy. Wind energy is considered environmentally beneficial and very economical. These benefits are cited as the primary reasons for using wind turbines to generate power across the world. An assessment of the country’s profile has been made, taking into consideration existing energy generation, crude oil production at current levels, gas flares that generate CO2 emissions, as well as industry, human activities, and grid electricity distribution. Iraq has power shortages, and several obstacles must be solved in order to satisfy projected increases in electrical demand. This analysis discovered that solar, wind, and biomass energy are now underutilized, but that they might play a key part in Iraq’s sustainable energy future. Wind energy, for example, has become an important aspect in reducing pollution and improving air quality. The usage of tiny wind turbines to generate power under Iraqi meteorological conditions is examined in this study. The research evaluates the wind system that is necessary to provide electric power for highway services including lighting and parking. According to the study’s findings, wind turbines can be used effectively for roadway illumination. The efficiency of a maximum wind turbine is determined by the blade design. For the planned use, the wind speed reported in Iraqi winter is pretty acceptable. Alternative and sustainable energy, wind energy, Iraqi climate are all index terms. The Iraqi government recently joined the Paris Climate Agreement and is now starting to encourage the participation of small and large consumers to generate electricity from renewable energy sources. This article analyzes the hybrid electrical system of solar and wind energy for the city of Dohuk, the northern part of Iraq, to find out the feasibility of this system compared to the local electrical network.
