Advances in wireless technology have resulted in an emerging broadcast-capable infrastructure. A major debate for such infrastructures is whether we should use push or pull to support large client populations. To date, push was suggested to provide a scalability that is not possible with pull. In this paper we conclude otherwise based on experimental prototype results. A major contribution of this paper is to show that pull-based algorithms outperform push-based ones. Contrary to the conventional wisdom, this is true even for environments where request processing and scheduling overheads are a significant factor. The goal is to minimize the average waiting time, efficiency and scalability for clients who access the broadcast channel. The objective of this is construction of distributed Information system that incorporates the ability to pull data.
