The Current Mobility Tracking System
[attachment=40650]
ABSTRACT
The current Mobility tracking system propose an integrated scheme for tracking the mobility of a user based on autoregressive models that accurately capture the characteristics of realistic user movements in wireless networks.
The mobility parameters are obtained from training data by computing Minimum Mean Squared Error (MMSE) estimates. Estimation of the mobility state, which incorporates the position, velocity, and acceleration of the mobile station, is accomplished via an extended Kalman filter using signal measurements from the wireless network.
By combining mobility parameter and state estimation in an integrated framework, user obtains an efficient and accurate real-time mobility tracking scheme that can be applied in a variety of wireless networking applications. Consider two variants of an autoregressive mobility model and validate the proposed mobility tracking scheme using mobile trajectories collected from drive test data. This result validates the accuracy of the proposed tracking scheme even when only a small number of data samples is available for initial training.
EXISTING SYSTEM
The existing system was used Visual Basic as front end, Microsoft SQL Server 2000 as backend and Microsoft XP as the operating system.
Existing system can’t support efficient tracking method. The existing system couldn’t find the node if the behavior of the nodes are same. This class of models is difficult to evaluate quantitatively. Moreover, such models were not sufficiently rich to enable accurate and precise real-time mobility tracking.
Mobility management in sensor networks is different from that in mobile ad-hoc networks because the movement of sensor nodes here is not random; rather, the movement of sensor nodes is purposeful. In such scenarios, it is important to have an efficient mobility management scheme to ensure that sensor node mobility is exploited in the best possible way,
e.g., to improve the quality of tracking. The existing system couldn’t find the node if the behavior of the nodes are same.
However, the applicability of such models may be limited since the parameters for one scenario may not be usable in other environments. Since the modeling assumptions are not validated with real data and compared with other models, the accuracy achieved by this class of models is difficult to evaluate quantitatively.
Moreover, such models are not sufficiently rich to enable accurate and precise real-time mobility tracking.
PROPOSED SYSTEM
The proposed system has overcome all problems in the existing system. A linear system model of mobility has been applied to real-time mobility tracking via various state estimation methods, such as Kalman filters. The proposed system provides a viable solution to mobility tracking for wireless networks. In this model, the mobility state consists of position, velocity, and acceleration. The proposed system consists of
1. Distributed Database:
Collections of data (e.g. in a database) can be distributed across multiple physical locations. A distributed database is distributed into separate partitions/fragments. Each partition/fragment of a distributed database may be replicated.
2. Mobile Sensor Network:
It Will Work in any environment .So no Problem about Dynamic changing topology. It used the Bayesian Estimation.
Bayesian Estimation:
Bayesian means Prediction. Predict Mobile Users Movement in our project with the help of Bayesian estimation.
THE COMMON LANGUAGE RUNTIME (CLR)
The common language runtime is the foundation of the .NET Framework. It manages code at execution time, providing important services such as memory management, thread management, remoting and also ensures more security and robustness. The concept of code management is a fundamental principle of the runtime. Code that targets the runtime is known as managed code, while code that does not target the runtime is known as unmanaged code.
XML WEB SERVICES
XML Web services are applications that can receive the requested data using XML over HTTP. XML Web services are not tied to a particular component technology or object-calling convention but it can be accessed by any language, component model, or operating system. In Visual Studio .NET, can quickly create and include XML Web services using Visual Basic, Visual C# , Jscript , Managed Extensions for C++, or ATL Server.
XML SUPPORT
Extensible Markup Language (XML) provides a method for describing structured data XML is a subset of SGML that is optimized for delivery over the Web. The World Wide Web Consortium (W3C) defines XML standards so that structured data will be uniform and independent of applications. Visual Studio .NET fully supports XML, providing the XML Designer to make it easier to edit XML and create XML schemas.
VISUAL BASIC .NET
Visual Basic.NET, the latest version of visual basic, includes many new features. The Visual Basic supports interfaces but not implementation inheritance.
Visual Basic.Net supports implementation inheritance, interfaces and overloading. In addition, Visual Basic .NET supports multithreading concept.
COMMON LANGUAGE SPECIFICATION (CLS)
Visual C#.NET is also compliant with CLS (Common Language Specification) and supports structured exception handling. CLS is set of rules and constructs that are supported by the CLR (Common Language Runtime). CLR is the runtime environment provided by the .NET Framework; it manages the execution of the code and also makes the development process easier by providing services.
Visual C#.NET is a CLS-compliant language. Any objects, classes, or components that created in Visual C#.NET can be used in any other CLS-compliant language. In addition, use objects, classes, and components created in other CLS-compliant languages in Visual C#.NET .The use of CLS ensures complete interoperability among applications, regardless of the languages used to create the application.
Enterprise-Level Database Features
The SQL Server 2000 relational database engine supports the features required to support demanding data processing environments. The database engine protects data integrity while minimizing the overhead of managing thousands of users concurrently modifying the database. SQL Server 2000 distributed queries allow to reference data from multiple sources as if it were a part of a SQL Server 2000 database, while at the same time, the distributed transaction support protects the integrity of any updates of the distributed data. Replication allows you to also maintain multiple copies of data, while ensuring that the separate copies remain synchronized.
Ease of installation, deployment, and use
SQL Server 2000 includes a set of administrative and development tools that improve upon the process of installing, deploying, managing, and using SQL Server across several sites. SQL Server 2000 also supports a standards-based programming model integrated with the Windows DNA, making the use of SQL Server databases and data warehouses a seamless part of building powerful and scalable systems. These features allow to rapidly delivering SQL Server applications that customers can implement with a minimum of installation and administrative overhead.
Data warehousing
SQL Server 2000 includes tools for extracting and analyzing summary data for online analytical processing. SQL Server also includes tools for visually designing databases and analyzing data using English-based questions.
