  1. WELCOME TO SEMINAR

  2. ROVER TECHNOLOGY ENABLING SCALABLE LOCATION AWARE COMPUTING

  3. ROVER TECHNOLOGY INTRODUCTION The technology which enables the scalable location-aware computing. This involves automatic availability of information and services based on a current location of the user. The user make avail location-aware computing through his PDA (Personal Digital Assistance).

  4. ROVER SERVICES • LOCATION-AWARE • WIRELESS ACCESS TECHNOLOGIES • BASIC DATA SERVICES • TRANSACTIONAL SERVICES • FILTER • ZOOM • TRANSLATE

  5. Physical architecture of Rover System

  6. ROVER ARCHITECTURE • END USERS • ROVER CLIENTS • WIRELESS INFRASTRUCTURE • SERVERS Server consists of:- • Rover Controller • Location Server • Media Streaming Unit • Rover Database • Logger

  7. ACTION MODEL Rover controller is built according to a concurrent software architecture which is called the action model. • Scheduling is done in atomic units called actions. • An action is a small piece of code • All actions are executed in a controlled manner by the Action Controller • The action is executed whenever an I/O response is received.

  8. SERVER OPERATION The transaction is called SERVER OPERATION when a client interacts with the Rover controller. A SERVER OPERATION IS A SEQUENCE OF ACTIONS.

  9. SERVER OPERATION A Server operation is in one of the following three states. They are:- • Ready-to-run: At least one action is eligible to be executed but no action is executing. • Running: One action is executing • Blocked: Server operation is waiting for some I/O response

  10. Logical Architecture of A Rover System

  11. ROVER CONTROLER Rover controller interacts with other components of the system through the following interfaces:- • Location Interface • Admin Interface • Content Interface • Back-end Interface • Server Assistants Interface • Transport Interface

  12. ROVER DATABASE The database in a Rover consists of two components:- • User Infobase and • Content Infobase

  13. PERSONAL DIGITAL ASSISTANT • A Personal Digital Assistant (PDA) is a HAND HELD COMPUTER, also known as a palmtop computer. • Newer PDAs commonly have color screens and audio capabilities, to be used as MOBILE PHONES (smart phones), web browsers, or portable media players. • Many PDAs can access the Internet, Intranet or extranet via Wi-Fi, or Wireless Wide AreaNetworks (WWANs). Many PDAs employ Touch Screen technology.

  14. MULTI-ROVER SYSTEM The multi-rover system is a collection of independent rover systems that peer with each other to provide the seamless connectivity to the users. The design of a multi-rover system is similar to the Mobile IP solution to provide network mobility to devices.

  15. BASIC FUNCTIONALITY OF THE ROVER SYSTEM • User activation/deactivation • Device registration /deregistration • Periodic broadcast of events from the rover controller • Interaction between users by text messaging/voice chat

  16. Display of the Rover Client

  17. iPAQ Rover Client

  18. CONCLUSION Rover is currently available as adeployable system using specific technologies, both indoors and outdoors. The ultimate aim of this scenario is to provide a completely integrated system that operates under different technologies.

  19. Future Works The short and long term projects of this paradigm:- • Experiment with limited capability devices • Location aware Streaming Devices • Interact with cellular providers and implement this mechanisms on cellular interface. • Multi-Rover System
