%X This paper presented a data aggregation algorithm based on MAX-MIN ant system(MMAS) in WSN.In this algorithm,used directed diffusion(DD)to deliver interest,and used MMAS algorithm to construct a minimum Steiner tree.The data sent by source nodes was transmitted to the constructed minimum Steiner tree and then was retransmitted to the sink node after aggregation.Compared with Dijkstra algorithm,NS2 simulation results show that this algorithm can help reduce network energy consumption and prolong the life span of the network.
