Software Example2: Non-uniform access algorithms. In a wireless environment, information is broadcast on communication channels to clients using powerful, battery-operated palmtops. To conserve the usage of energy, the information to be broadcast must be organized so that the client can selectively tune in at the desirable portion of the broadcast. Most of the existing work focuses on uniform broadcast. However, very often, a small amount of information is more frequently accessed by large number of clients while the remainder is less in demand. Using the local quality principal, non-uniform algorithms can be developed that predict the suitable access behavior for a particular operation.
