He has more than five years of software design and development experience. He has thorough knowledge of Java programming and IBM products related to pervasive computing, including WebSphere Application Server, WebSphere Portal Server, WebSphere Everyplace Access, WebSphere Everyplace Server for Telecom, DB2 UDB, and MQ Series. He is also familiar with Telecom specifications, such as Parlay/OSA and SIP.

Summary:  This tutorial gets you started with IBM Enterprise LAS middleware. Learn the concepts behind the middleware and write a simple location-tracking Web application with the help of Asynchronous JavaScript and XML (Ajax) and Scalable Vector Graphics (SVG) technologies. With these best practices in mind, you'll be on your way to building faster location-tracking systems that can easily integrate with positioning/sensoring technologies, such as RFID and Zigbee.

Before you start

               

This tutorial helps you create a custom-made indoor locating/tracking Web application from scratch using IBM Enterprise Location Aware Services (LAS) middleware, Ajax, and SVG.

       

About this tutorial

       

In this tutorial, we briefly introduce the IBM Enterprise LAS middleware, an indoor location-aware middleware prototype provided by IBM Watson Research Center and the China Software Development Lab.        

       

With an easy-to-understand example, you will build a Web-based, real-time positioning application step by step. By the end of this tutorial, you will understand what IBM enterprise LAS middleware can do for you, and get acquire the skills necessary to build a real-time location tracking Web application from scratch.

Objectives

       

The problem with building real time, location-tracking Web applications is twofold. First, it is difficult to visualize the sense of "real time movement" on your Web interface. Second, it is tedious to integrate various positioning/sensoring technologies, such as RFID, Zigbee, or UWB (Ultra Wide Band) seamlessly with your location systems.        

       

      This tutorial proposes best practices to solve these issues using a combination of SVG, Ajax technologies, and the adapter architecture of IBM Enterprise LAS middleware. Under proper license agreements, your projects can reuse this tutorial's code as a stepping stone to building full-blown Web-based location-tracking systems that will not lag and can easily integrate various positioning/sensoring technologies (we use Zigbee as an example).
