Sparse mobile ad-hoc network called DTN may violate one or more assumptions of existing TCP/IP protocol and may not be well served by other kind of network like DTN. In this network end-to-end disconnection is more common than connection. So positioning and tracking of mobile devices to have latest location in DTN becomes more important. In this paper, we have surveyed some methods of positioning...
Wireless sensor networks have the potential to become the future pervasive sensing technology. Large number of sensors and the major application scenario require manual location that may cause sensor position variation problem However, we need mechanisms to localize sensors randomly and control the correspondent movement. In such item, we propose in this paper a WSN policy using the peddling information...
There are many patterns in the everyday life of a person, some of which are more conscious, others are less. Going to work on weekdays, or visiting friends on every second Saturdays are typically conscious ones, which are natural to human, but hard to recognize for a computer. In this paper we are introducing a set of algorithm proposals, designed to efficiently recognize routines of human movement...
Location tracking of mobile entity becomes a research challenge for applications in vehicular networks, mobile sensor networks and mobile adhoc networks. The GPS based tracking in vehicular networks has limitations in certain scenarios such as inside tunnels, tall buildings, dense forests, etc. Tracking of fast-paced mobile entity (say mobile node) finds applications in vehicular networks such as...
In this paper we present a localization technique for tracking and positioning services in self-organizing hybrid networks, where both indoor and outdoor scenarios coexist. In the proposed framework, outdoor anchor nodes act as reference nodes for estimating the position of mobile nodes, which are moving in a neighboring indoor region. The mobile nodes share some location information for estimating...
Statistics show that the number of cars is increasing rapidly and so is the number of car theft attempts, locally and internationally. Although there are a lot of car security systems that had been produced lately, but the result is still disappointing as the number of car theft cases still increases. The thieves are inventing cleverer and stronger stealing techniques that need more powerful security...
Accurate local positioning systems usually use a network of anchor nodes at known locations to track mobile nodes based on the measurement of the time of arrival (TOA) at anchor nodes of beacon signals transmitted by the mobile nodes. To localize the mobile node either TOA processing, where the unknown transmit time is estimated along with the node location, or time difference of arrival (TDOA) processing,...
Currently available asset tracking systems are not cost effective in mobile and wireless computing infrastructures, and they do not learn the asset's route to act accordingly. Hence our main goal is to not only to track mobile assets by using an efficient geographical tracking approach, but also adapt their routes by means of intelligent route learning techniques. We thus designed and implemented...
Smart phones are becoming visual computing powerhouses. Using sensors such as camera, GPS, and others, the device can provide a new user interface to the real world, augmenting user's view of the world with additional information and controls. Combining computation with image capture allows new kind of photography that can be more expressive than is possible to obtain with a traditional camera. New...
Geospatial Information System (GIS) is a tool for manipulating, integrating and displaying geographically referenced information. It is a powerful system with high accuracy that is being used as the main backbone for a variety of path planning and navigation technologies widely used in the industry today. Tracking, security management, fleet management and industrial robot navigation are some regular...
Location-based tracking systems (LTSs) use a variety of technologies to record the locations of objects. An LTS can increase the risks to the privacy and security of individuals. Previous studies have failed to distinguish between losses and violations of privacy when the locations of individuals are recorded by an LTS. We argue that individual privacy is threatened not by the collection of public...
This paper presents a differential GPS carrier phase technique for 3D outdoor position tracking in mobile augmented reality (AR) applications. It has good positioning accuracy, low drift and jitter, and low computation requirement. It eliminates the resolution of integer ambiguities. The position from an initial point is tracked by accumulating the displacement in each time step, which is determined...
