摘要

Research on push-based systems has introduced several outstanding theoretical analyses and algorithms, aiming to optimize the clients' mean waiting time under several conditions. However, the computational and memory requirements aspect has been neglected to a great extend, thusly undermining the primary advantage of push systems over pull-based ones, i.e. their minimal cost. In this paper influential and top performing, well-known algorithms are evaluated from a cost aspect. It is shown that radical improvements are required for them to be realizable. Moreover, a new cost-efficient broadcast scheduling algorithm is introduced, achieving nearly top performance with minimal CPU and memory requirements. The new algorithm also promotes the adaptivity of push systems to the clients' changing needs, another factor that has not been taken into account by traditional approaches.
