This paper researches on aggregation strategy in wireless sensor networks, proposes a distributed method for finding the center of a graph and proposes a center aggregation algorithm that based on this distributed method. It introduces the process of finding center and building aggregation tree, analyzes the impact of network density and the relatively distance between the event and the sink on energy saving. From both mathematics consequence and emulator result, it is proved that the center aggregation has validity.
