Cognitive radio networks(CRNs)is new paradigm that provides the capability to share or use the spectrum is an opportunistic manner. It ability to sense the unused spectrum at a specific time and location (spectrum hole).Cognitive Radio (CR) technology is a promising solution to enhance the spectrum utilization by enabling unlicensed users to exploit the(More)
Virtualization is a key concept in enabling the computing as a service vision of cloud based solutions. In other words, Virtualization is software which makes it possible to run multiple Operating Systems and multiple applications on the same server at the same time. In this case the Physical Machine may get overloaded due to heavy user interactions. This(More)
The rapid growth of wireless devices has to a dramatically increased in the needs of spectrum access from wireless services. Cognitive Radio (CR) technology is a promising solution to enhance the spectrum utilization by enabling unlicensed users to exploit the licensed spectrum in an opportunistic manner. In this paper, sequential channel sensing problems(More)
An integration of distributed generations (DGs) to the utility grid has raised the need for good power quality, safety operation and islanding protection of the grid interconnection. This paper presents the classification and detection of faults in a distributed generation, particularlyphotovoltaic (PV) grid-connected system. The initial step in fault(More)
Water level control is highly important in industrial applications. In this work a simple water level controller based on fuzzy logic is proposed. The fuzzy logic controller is based on Mamdani type Fuzzy Inference System. A boiler system is an integral component of a thermal power plant and control of water level in the drum of boiler system is a critical(More)
