Broadcasting is used as a means of efficient and fast communication between an information-server to all the clients. Many broadcasting schemes have been proposed in the literature to achieve better performance in different communication scenario. In this paper, a new adaptive dynamic heuristic real-time multiple data-item broadcast-on-demand scheme is proposed. This proposed scheme (DHST-alpha,beta), which runs on the server, is used for preparing a broadcast schedule for temporal data (having a validity period) to satisfy client requests having multiple data-items with a fixed hard deadline time. Each request is considered as an atomic transaction i.e., a request transaction is supposed to be complete if and only if all the requested data-items in the request transaction could be broadcasted within the specified time limit. Simulation is done to study the performance of the proposed scheme together with the existing schemes.
