摘要
无线体域网具有很强的应用相关性,不同的应用场景下对网络有不同的要求,必须有针对性地对网络进行设计.从无线体域网的生物安全性角度出发,建立了适合体域网应用的LEACH算法模型,在对簇头边缘化等缺陷进行改进之后,综合考虑了无线体域网中资源的利用率、单个节点的生命周期、不同应用场景下的重要节点不同等因素,进一步改进为适于无线体域网应用的LE-WBAN算法.通过NS2下的仿真与分析证明,该算法有效延长了单个节点和整个网络的生命周期,符合无线体域网低功耗、高能效的要求.
Wireless body area network has a strong correlation between applications, and different scenes have different demands for the network, so it is necessary to make pointed references to the network design. This paper sets up a LEACH algorithm model for WBAN based on the biological safety, after improving some of the drawbacks, such as cluster head marginalization,it considers the utilization rate of resources as well as the life cycle of the single nodes in the WBAN and important nodes in different scenes and then proposes a low energy-wireless body area network algorithm. The results of the NS2 simulation and analysis prove the LE-WBAN prolongs the life of single nodes and the network effectively, which conforms to the low power consumption and energy-efficient requirements of the WBAN.
