EXISTING SYSTEM:
Previous wireless broadcast system has only considered snapshot queries over static data .
Broadcasting is done in such a way that ,whole processing occurs at server.
Disadvantages:
It doesn’t work for moving objects.
Heavy load at the server degrades the performance.
More power consumption(more tuning time) and access latency .
PROPOSED SYSTEM:
Server broadcasts the index of objects after updation(if any) so that client tunes into broadcast channel and process the queries locally.
It uses BGI(Broadcast Grid Index) ,which extends to the case that the data are also dynamic.
Server uses air indexing to broadcast the data.
Advantages:
Air indexing helps in terms of energy consumption and access latency.
Load at the server is reduced.
Works efficiently for moving objects also.
