It wastes a lot of energy to dump all measurements to Sink with multi-hop method,and now a promising way is to do distributed in-network data aggregation before transmission.In this paper,a thorough survey of data transmission technology in WSN is provided in the perspective of data aggregation,particularly the algorithm of DWT_IRR.Typical algorithms are compared in a table,and some directions of future work are proposed.
