LOCATION BASED SPATIAL QUERY PROCESSING IN WIRELESS BROADCAST ENVIRONMENTS-MOBILE COMPUTING

Abstract: Location-based spatial queries (LBSQ s) refer to spatial queries whose answers rely on the location of the inquirer. Efficient processing of LBSQ s is of critical importance with the ever-increasing deployment and use of mobile technologies. We show that LBSQ s has certain unique characteristics that the traditional spatial query processing in centralized databases does not address. For example, a significant challenge is presented by wirel ....etc

Abstract:
PRIVACY-CONSCIOUS LOCATION-BASED QUERIES IN MOBILE ENVIRONMENTS

In location-based services, users with location-aware mobile devices are able to make queries about their surroundings anywhere and at any time. While this ubiquitous computing paradigm brings great convenience for information access, it also raises concerns over potential intrusion into user location privacy. To protect location privacy, one typical approach is to cloak user locations into spatial ....etc

A System for Peer-to-Peer Video Streaming in Resource Constrained Mobile Environments
Introduction
 Peer-to-Peer based near-live video streaming is becoming popular with users of fixed-line broadband.
 Unavailable to mobile users because they cannot meet the bitrates requirements.
 P2P-TV system enables users in a physical proximity to retrieve video chunks in a cooperative way.
 The coordinated and efficient usage of all wireless resources available to a group of mobil ....etc

INTRODUCTION
PERVASIVE ENVIRONMENT
Pervasive computing is a rapidly developing area of Information and Communications Technology (ICT).
Pervasive computing involves three converging areas of
ICT:
Computing (‘devices’),
Communication (‘connectivity’) and
User interfaces.
VIRTUAL WALL
As sensor-rich pervasive environments become more common, users’ privacy will be at Increased risk. Sensors can record a user’s activities and personal information such as heart rate, ....etc

Abstract—Channel asymmetry and high fluctuation of channel conditions are two salient characteristics of wireless channels in mobile environments. Therefore, when using IEEE 802.11 devices in mobile environments, it is critical to have an effective rate adaptation scheme that can deal with these issues. In this paper, we propose a practical rate adaptation scheme called Rate Adaptation in Mobile environments (RAM) and implement it in the MadWifi device driver. RAM uses a receiver-based approach to handle channel asymmetry and a conservative S ....etc
