无线传感器网络由传感节点和sink节点构成,传感节点由于采用电池供电,每个节点的能耗均可能影响整个网络的生命周期,因此,研究降低节点能耗、提高节点生存时间的方法具有重要意义.通过研究网络节点能耗均衡方法,以期提高整个网络的生命周期.首先,研究无线传感器网络的生存时间优化模型,然后设计支持生存时间优化的自适应多区域分层路由算法(SARMAL).MATLAB仿真实验表明,对于节点分布较稀疏或监测区域较大的网络,SARMAL算法性能较好,设计的算法可以较好的延长网络生存时间.
The wireless sensor network consists of sensor nodes and sink nodes. Since the sensor nodes are powered by batteries, the energy consumption of each node may affect the life cycle of the entire network. Therefore, the research on reducing the node energy consumption and increasing the node lifetime has It is important to research the energy consumption equalization method of network nodes in order to improve the life cycle of the whole network.Firstly, the life time optimization model of wireless sensor networks is studied, then the adaptive multi-area hierarchical routing algorithm (SARMAL) The simulation results of MARTLAB show that the SARMAL algorithm performs well for networks with sparse nodes or large monitoring areas and the designed algorithm can prolong network lifetime better.
