Introduction: A key application of sensor networks in smart environments is in monitoring the activities of people. We develop several scenarios in which ultrasonic sensors are used for monitoring patients and the elderly. In each scenario, we apply different algorithms for data fusion and sensor selection using quality-based or time-division approaches. We have devised trajectory-matching […]

Introduction: Power Line Device Switching System is one of the most common and useful consumer electronics gadgets in the world today. It incorporates both Communication & Digital Electronics filed. They provide us with countless conveniences in our daily lives. As the device is so much popular and part of every-day-activities, many add-on circuits are constructed

Introduction: Electricity is an extremely handy and useful form of energy. It plays an ever-growing role in our modern industrialized society. The electrical power systems are highly non-linear, extremely huge, and complex networks. Such electric power systems are unified for economic benefits, increased reliability, and operational advantages. They are one of the most significant elements

Introduction: Now a day’s electronic devices become smaller and lower in power Requirements, and they are less expensive. We have begun to adorn our bodies with personal information and communication appliances. Such devices include cellular phones, pagers, personal digital assistants, and many more. But currently, there is no such method for these kinds of devices

Introduction: LiFi is the transmission of data through illumination by taking the fiber out of fiber optics by sending data through a LED light bulb that varies in intensity faster than the human eye can follow. Li-Fi is the term some have used to label the fast and cheap wireless communication system, which is the

Intoduction:                 Automation is today’s fact, where more things are being completed every day automatically, usually the basic tasks of turning on or off certain devices and beyond, either remotely or nearby. The control of the devices when completely taken over by the machines, the process of monitoring and reporting becomes more important. We are
