In this paper, we classify data aggregation into two kinds: single-query data aggregation, inter-query data aggregation. As we know, single-query data aggregation is a hot issue in sensor networks, e.g. TAG (S. Madden, et al., 2002) makes big contribution to single-query data aggregation. But less attention are paid to inter-query data aggregation. We analyze problems existing in inter-query data aggregation as it is more complicated than single-query data aggregation, and then we resolve these problems and evaluate efficiency of our work by computing consumed energy.
