摘　　要：能耗过大及数据拥塞直接影响无线网络的可靠性及生存能力,是无线网络拓扑方法研究中的两个关键问题.笔者提出了一种基于节点优化的无线传感网络拓扑控制方法.通过构建网络节点模型,基于网络生存能力和节点可靠权值约束进行节点权值应用的优化处理.计算机仿真表明,本文方法明显降低了数据传输的拥塞程度,在提升网络稳定的同时,有效延长了网络的生存寿命.Excessive energy consumption and data congestion directly affect the reliability and viability of wireless networks, which are two key issues in the research of wireless network topology methods. This paper presents a topology control method for wireless sensor networks based on node optimization. The network node model is constructed to optimize the application of node weights based on network survivability and reliability weight constraints. Computer simulation results show that the proposed method significantly reduces the congestion of data transmission, improves the stability of the network, and effectively prolongs the lifetime of the network.
