Introduction
Rover refer to this paradigm as Location aware computing.
Traditional notions of Time-aware, User-aware, and Device-aware. + Local-aware (in Rover).
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)
Devices (laptop, PDA, cellular phone)
Scales to a very large client population.
Rover achieves this through fine resolution application specific scheduling of resources at the servers and the network.
Rover Services
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)
Services that require location manipulation are a particularly important class of data services in Rover.
Locations an important attribute of all objects in Rover. – value, error, timestamp
Map based services
Filter : Applied to maps to select the appropriate subset of objects to display to the users.
Zoom : Displayed map identifies it’s granularity.
Translate : Translated from the previously displayed
map.
Rover Architecture
Rover maintains a user profile for each end-user, that defines specific interests of the user and is used to customize the content served.
Rover-clients are the client devices through which users interact with Rover. Rover maintains a device profile for each device.
Action model
Ready-to-run: At least one action of the server operation is eligible to be executed but no action of the server operation is executing.
Running: One action of the server operation is executing ( in a multi-processor setup, several actions of the operation can be executing simultaneously ).
Blocked: The server operation is waiting for asynchronous I/O response and no actions are eligible to be executed.
Conclusions
I believe that Rover Technology will greatly enhance the user experience in a large number places, including visits to museums, amusement and theme parks, shopping malls, game fields, offices and business centers.
The system has been designed specifically to scale to large user populations. Therefore, we expect the benefits of this system to be higher in such large user population environments.
