%X The flaws of traditional cache invalidation reporting strategies are with poor bandwidth efficiency and extensive electrical energy consumption. Aiming at these problems, we proposed a new broadcasting strategy which partitions the invalidation report dynamically. By considering the query ratio, refresh rate and the size of data items, this strategy tries to broadcast the updating data items through different invalidation mode. It was proved that the new strategy is superior to the traditional cache invalidation report strategy in terms of bandwidth efficiency, electrical energy consumption, and the query delay.
