Abstract: As the wireless technology overwhelmingly occupies the consumer electronics market, the booming demands of the mobile users are largely unaccommodated. Thus wireless data broadcasting systems gain increasing attentions recently. Two wellknown metrics for evaluating wireless data broadcasting systems are Access Latency and Tuning Time. In order to reduce these two factors, many existing techniques have to make a tradeoff between the power consumption and the quality of services. In this paper, an energy-efficient Hybrid Asynchronous Multiple Hashing scheme named HAMHash for multi-channel broadcasting systems was proposed, which deals with variable data size and non-flat distribution of queries in multi-channel circumstance. Furthermore, algorithms of data allocation and retrieval for skewed broadcast are presented. Quantitative theoretical and experimental analysis of the system performance verifies the effectiveness of our scheme.
