Abstract: Through analyzing the characteristics of topology distribution of interest network, a new parameter which describes network interest distribution was introduced. And a aggregation search algorithm ( ASA) for the heterogeneous interest networks was proposed, which uses parameter to find suitable search radius according to the giving search recourse. ASA can select the optimized network according to network delay. Then the selected network uses optimized search method by choosing search radius. The simulation results show that ASA has better performance than traditional data search algorithm.
