Cache Consistency Maintenance Based on Adaptive Broadcast

In order to improve the efficiency of cache data in mobile environment, characteristics of related work are analyzed, and a method is proposed to maintain the cache consistency based on adaptive broadcast. The data access pattern is divided into exclusive and sharing, according to the pattern of access and update frequency of the data, Three ways are adopted, i.e.the period, update counter and data state to dynamically adjust the frequency and content of data broadcast. The correctness of this method based on the theory of transaction serialization in database is testified that verifies the efficiency through experiment. The method can be applied in various wireless networks for their data cache.
