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 Channel asymmetry and high fluctuation of channel conditions are two salient characteristics of wireless channels in mobile environments. Therefore, when using IEE 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 SNR ....etc

SSUM: Smart Server Update Mechanism For Maintaining Cache Consistency In Mobile Environments Mobile Computing

This paper proposes a cache consistency scheme based on a previously proposed architecture for caching database data in MANETs. The original scheme for data caching stores the queries that are submitted by requesting nodes in special nodes, called query directories (QDs), and uses these queries to locate the data (responses) that are stored in the nodes that requested them, called caching nodes (CNs). The consistency scheme is serve ....etc

Introduction

Object oriented programming has been the dominant programming paradigm for more than a decade.

OOP languages provide a rich set of features that provides significant software engineering benefits.

The increased productivity provided by these features comes at a justifiable cost of complexity in the runtime environment ,which actually leads to reduced performance and increased energy consumption of programs.

Modern battery driven mobile and wireless devices req ....etc

ABSTRACT

Current access control schemes focus on the user and their rights and privileges relating to the access to both initiating functionality and accessing information. This approach, while appropriate with resp ....etc

Abstract :

Current trends in computing technologies are drifting towards distributed and parallel computing. These topologies emphasize on concurrent access schemes. Because of distributed computing, the use of shared resources like databases, memory, etc. is growing. Locking mechanisms can be used effectively to achieve high concurrency levels without corrupting the resources. There are a wide range of synchronization protocols, some providing strong consistency while others granting weak consistency. There is a trade-off between complexit ....etc
