Environmental pollution affects human health and reduces the quality of our land and water. As a result, there is great interest in monitoring water and air quality and ensuring that all areas are compliant with legislation. Ubiquitous environmental monitoring places considerable demands upon existing sensing technology. The combined challenges of system longevity, autonomous operation, robustn...

While demand for electricity continues to grow, expansion of the traditional electricity supply system, or macrogrid, is constrained and is unlikely to keep pace with the growing thirst western economies have for electricity. Furthermore, no compelling case has been made that perpetual improvement in the overall power quality and reliability (PQR) delivered is technically possible or economical...

Given the increasing number of IP streaming video customers, service providers are seeking an efficient way to monitor in real time the offered quality of service, as perceived by each end user. Since real-time video quality assessment via image processing algorithms is quite bandwidthand processing-power-demanding, a feasible alternative could be to monitor the network-level quality of service...

In this paper, we investigate the relay placement and power allocation for decode-and-forward (DF) cooperative relaying over correlated lognormal shadowed Rayleigh fading channels. Assuming that maximum-ratio combining is performed at the destination, we first derive an upper bound of symbol error rate (SER) withM-phase-shift keying (PSK) modulation. Then, three optimization problems are formul...

Development of distributed generations’ technology, trends in the use of these sources to improve some of the problems such as high losses, low reliability, low power quality and high costs in distributed networks. Choose the correct location to install and proper capacity of these sources, such as important things that must be considered in their use. Since distribution networks are actu...
