%X In order to solve the problem that existing algorithm of building broadcasting structure is not fully consider the skew of data access,proposed an algorithm of building broadcasting structure which based on CF index tree. According to the position of data in CF index tree, the algorithm considered the request of hot data and repeatedly broadcast hot data and corresponding index node in a broadcasting cycle to save the access time of mobile users. Experimental results show that the improved broadcasting structure is effective.
