Broadcast data organizations and client side cache

Broadcasting provides an efficient means for disseminating information in both wired and wireless setting. In this paper, we study different client side cache organizations for various types of multiversion data broadcast, i.e., data broadcast in which more than one value is broadcast per data item. Besides increasing the concurrency of client transactions, multiversion broadcast provides clients with the possibility of accessing multiple server states. For example, such a functionality is essential to support applications that require access to data sequences and have limited local memory to store the previous versions, such as in the case of sensor networks.
