New cache strategy based on broadcasting in mobile computing environments

The cache strategy should not only concern the historical accessing situations of the data,but also consider the broadcasting probability of the data.After carefully researching the influence of the broadcasting frequency changes to the cache strategies,a method to determine whether the data should be replicated or not was proposed.This method is based on the average respond time of the Mobile Client(MC) spending in reading data from the broadcast.This new cache strategy can make MC avoid waiting for a long time while accessing some data,and cut down the cost of cache management.Therefore,the MC's performance will be advanced obviously.
