摘　　要：提出了一种基于数据流跟踪的能量模型,通过跟踪数据流在网络中的整个过程来计算全网的能量消耗,是一种不受网络结构限制的普遍适用的能量模型;在此基础上,建立了基于能耗的网络优化模型,针对链式和簇式结构进行了拓扑、功率和路由方面的优化设计,仿真结果证明了理论分析的正确性。A novel energy model for wireless sensor networks is proposed based on the traced data flow. It can be used to compute the whole energy consumption of wireless sensor networks and has pervasive applicability. The energy optimization model is built for wireless sensor networks, and then the optimization design of topology, transmission power and routing are implemented in network of link and clustering architectures, finally the simulation results validate the theoretical results.
