Cognitive radio is emerging wireless technology which offers reallocation and reutilization of the unused spectrum. Not all the network runs with highest load at all the time. Therefore part of spectrum always remains unused. In a multi radio environment cognitive radio allows the user to request for spectrum while roaming from another service provider. In ...

An embedded system is a combination of software and hardware to perform a dedicated task. Some of the main devices used in embedded products are microprocessors and microcontrollers. Microprocessors are commonly referred to as general purpose processors as they simply accept the inputs, process it and give the output. In contrast, a microcontroller not only ...

Passwords square measure the foremost widespread and represent the primary line of defence in computer-based security systems; despite the existence of additional attack-resistant authentication schemes. so as to reinforce watchword security, it’s imperative to strike a balance between having enough rules to keep up smart security and not having too several rules that might compel ...

Cloud computing economically enables customers with limited computational resources to outsource large-scale computations to the cloud. However, how to protect customers’ confidential data involved in the computations then becomes a major security concern. In this paper, the authors present a secure outsourcing mechanism for solving large-scale systems of Linear Equations (LE) in cloud. Because applying ...

In this paper, the authors discuss about the stream of embedded system which can be defined as is a combination of computer circuitry and software that is built into a product for purposes such as control, monitoring and communication without human intervention. This paper discuss about the implementation of a CMOS camera (OV5647) sensor with ...
