Through using the high - energy nodes in hterogeneous network achieving energy management， the article analyzes isomorphic sensor network's deficiency on capability and survival time. The article puts forward the idea of heterogeneous network architecture with a few high - energy nodes, and demonstrats the stability of the heterogeneous network. It mainly analyzes how the high - energy node should allot, and the performance of the hetergeneous netwok. The results showed that: heterogeneous network has good stability, the survival time; the mount of data can increase 90％ ; the heterogeneous network consumed lower energy than homogeneous network.%为通过使用高能量节点的异构网络架构来实现能量管理,分析了同构传感器网络在性能和网络生存时间上的不足,提出了拥有少量高能量节点的异构传感器网络架构,并研究高能量节点的能量分配问题以及异构网络的性能.实验结果表明,异构网络具有良好的稳定性,在相同网络生存时间条件下,异构网络数据量可以提高90%,而总能量消耗低于同构网络.
