The use of data broadcasting in wireless environment has been of much interest especially to deal with the exponential increase of mobile users due to its scalability. In this paper, we present a unified broadcast model in multi-channel wireless databases and its comprehensive performance analysis. This model aims to minimize query access time, tuning time and power consumption of mobile users when obtaining broadcast database items. This scheme also concerns with single and multiple data items request. A prototype and simulation-based experiment has been developed to evaluate the performance of the broadcast model. We compare the performance of the proposed model against the conventional scheme and we found that the proposed unified model provides substantially better performance in every aspect of the evaluation. It is also shown that the results of our simulation are very close to those obtained from the prototype system.
