摘要：At present, most aggregation routing algorithms for WSNs assume that aggregation expends are so little as to be neglected. But with the growing demand for the collection of multimedia data, the aggregation expends are much larger and can’t be neglect. In view of this problem, this paper proposes an adaptive aggregation routing algorithm with the minimal energy consumption (RMEAAT). Firstly, it constructs an -balancing spanning tree on the basis of SPT and MST as the initial communication path. And then it defines the aggregation benefit with consideration of aggregation expend and transmission expend, and data are adaptively judged whether to aggregate at every node of -balancing spanning tree according to aggregation benefit in the process of transmission. Correspondingly, the initial transmission path is gradually improved in terms of the aggregation judgment. The simulation results show that RMEAAT algorithm has better performance in WSNs with different aggregation expends and fusion degrees.
