摘　　要：针对无线传感器网络非均匀分簇路由协议在数据传送过程中的问题,本文提出了一种自适应数据传送机制,改善数据在传送过程中的实时性;其核心思想是:在LEACH协议概率分簇的基础上,通过分层选举和优化簇首数量,在能量消耗均衡且最小的情况下,利用网内数据融合、实时性标识结合内部"中断"的处理机制;仿真实验表明,ADTUC算法能够有效的改善数据传送的效率,提高网络的实时性,平衡网络的能量消耗,延长网络生命周期,比LEACH协议网络生命期提高54%。The paper discussed the unequal clustering routing protocol for wireless sensor networks concerning data transmission, and proposed an adaptive data transfer mechanism, to improve the real--time data transmission. It mainly described that basing on the probabihty clustering in the LEACH protocol, getting through the cluster head hierarchical election and optimizing the number of the cluster head, making the consumption of energy equalization and minimality, Meanwhile, using data fusion of the internalnetwork and identification of the real--time with the ＂ Interrupt ＂ processing mechanism. Simulation results show that： ADTUC algorithm can effectively improve data trans mission efficiency and network real time, balancing the network energy consumption and prolong network life cycle, the network lifetime compared with LEACH protocol increased 54 %.
