Abstract

In a wireless communication environment, on-demand broadcasting is an attractive information delivery method, while data caching is an important technique used to improve system performance. However, most of the wireless data caching techniques in the literature were designed for push-based broadcast systems. Due to variable item sizes, data updates and frequent client disconnections, the design of client cache management in an on-demand broadcast system becomes a challenge. In this paper, we propose an efficient gain-based cache replacement policy, SAIU, for on-demand broadcasts. In SAIU, the influence of data size, data retrieval delay, access probability and update frequency is considered together. Simulation-based performance evaluation shows that the proposed policy substantially outperforms the existing strategies.
