摘　　要：针对无线传感器网络能耗过快问题,从均衡网络负载和降低簇间传输能耗两方面进行研究,提出基于动态分区的高效路由算法。均衡网络负载方面综合考虑节点及网络的剩余能量,平均剩余能量和"热区"问题,提出基于动态分区的非均衡分簇办法,解决了网络中局部负载过重而导致的网络寿命过短问题;降低簇间传输能耗方面,提出了基于虚拟MIMO(多输入多输出)的协作节点优化选择方法,实现以较小的能耗获得极大的传输效率。仿真结果表明:网络负载方面,文中算法与课题组成员前期提出的改进LEACH以及ENAC方法相比更加稳定且有效;网络寿命方面,相比传统的单入单出LEACH方法和基于虚拟多入多出的改进LEACH方法,文中方法极大降低网络能耗,延长网络生命周期。In view of drawbacks of energy consumption in wireless sensor networks （ WSNs）, a dynamical partition based efficient routing algorithm is proposed. Considering network load and the energy consump- tion of the inter cluster,a novel dynamical partition non-uniform（DPNU） clustering scheme is presented considering the remaining energy and the consumption energy of the nodes and the entire network, thus solving the ＂hot spots＂ problem caused by the uneven load energy. To reduce the energy cost of the inter- cluster, reasonable cooperative nodes are selected to form virtual MIMO structures. Simulation results show that the DPNU is outstanding than improved LEACH and ENAC methods in the network load ;the network lifetime is effectively prolonged compared with the LEACH and virtual MIMO based improved LEACH methods.
