A location and tracking system becomes very important to our future world of pervasive computing. An algorithm for accurate location information is being incorporated in the human walking model and in the blind human walking model. We want to implement an accurate location tracking mechanism using Zigbee along with GPS, we have incorporated Markov chain(More)
Speckled Computing is an emerging technology in which data will be sensed and processed in small (around 5*5 sq, millimeter) semiconductor grains called Specks. A dense and non-static wireless network of thousands of these specks is called a specknet. This specknet will collaborate among themselves to extract information from the data. Speckled computing(More)
—Development of an accurate, less-complexity indoor positioning system using Smartphone is the scope of this research. In an indoor environment, a Smartphone can communicate with the signals of opportunity. The signals for experimentation include Wi-Fi, Bluetooth, GSM and optical signals which will almost be available in all the buildings and a Smartphone(More)
As wireless sensor networks are ubiquitous in nature, localization is an important factor to be solved. Localization of an unknown node can be identified through a set of reference nodes. In this paper, we present a novel hybrid localization technique, which determines the exact location coordinates of an unknown node through the combination of both range(More)
