IntroductionRover stands for Remotely Operated Video Enhanced

Receiver (ROVER).Location-aware computing involves the automatic tailoring

of information and services based other current location of the user.

Rover achieves this through fine resolution application specific scheduling of resources at the servers and the network.

What is Scalable Location Aware Computing..?

Location service that can track the location of every user, either by automated location determination technology or by the user manually entering current location.

Available via a variety of wireless access technologies. (IEEE 802.11 wireless LANs, Bluetooth, Infrared, cellular services)

Rover Controller •The interaction of the Rover

controller with all other components of the system is presented .•The Rover controller

interacts with the external world through the following interfaces:

Rover

Rover Controller(Cont…) Admin Interface: This interface is used by system administrators to over see the Rover

system, including monitoring the Rover controller, querying client devices, updating security policies, issuing system specific commands.

7

Rover

Rover Controller(Cont…)Content Interface:This interface is used by the content provider to update the content

that is served by the Rover controller to the client device

Having a separate content interface decouples the data from the control path.

Rover Services• Rover offers two kinds of services to its users.:-Enables a Basic set of data services in different media formats,

including text, graphics, audio, and video.

Transactional services coordination of state between the clients and rover servers. ex). e-commerce interactions.

Basic Data Service Basic data services use text, graphics, audio,and video

formats.Dynamically to specific data components through the device

user interface. Rover filters the available media formats according to the

device’s capabilities. The basic data service involves primarily one-way

interaction

Transactional Data Services.. Transactional services have commit semantics that require coordinating state between the clients and Rover servers.

E-commerce & E-Banking interactions are examples of this service class.

ConclusionWe believe that Rover Technology will greatly enhance the user

experience in a large number places, including visits to museums, shopping malls, game fields, offices and business centers.

The system has been designed specifically to scale to large user populations.
