Technological advances in miniaturized devices, sensors and wireless networking have led increasingly to the integration of sensors and devices with users and physical environment, leading to ubiquitous computing systems. Ubiquitous computing (ubicomp) supports a widely networked infrastructure of a multitude of sensing and computing devices. It ensures that information is accessible everywhere and moves the interaction beyond the desktop and into the real world with a special attention to
