| 摘 要: 近年来，随着对健康医疗水平的重视，体域网迅速发展起来。但是由于无线电作为传输介质传输能耗较 高，并且穿戴在人体的传感器节点往往较小，这都导致网络生存周期较短。此外，体域网中各节点的相对位置会随着用 户不同行为模式及姿态而发生变化。如何针对动态拓扑结构选择路由，保证最大化网络的生存周期，是本文的主要研究 内容。本文提出一种基于卡尔曼滤波的动态路由算法，来自适应变化的网络拓扑，并同时达到延长网络生存周期的目 的。 |

| Abstract: In recent years,with the emphasis on health care,body area network has developed rapidly.However,due to the high energy consumption of radio transmission as a transmission medium and the small numbers of sensor nodes worn on human body,the network lifetime is shorter.In addition,the relative position of each node in the body area network will change with user's different behavior patterns and gestures.How to select routing for dynamic topology to maximize the lifetime of the network is the main content of this paper.In this paper,a dynamic routing algorithm based on Kalman Filtering is proposed,which adapts to the changing network topology and prolongs the network lifetime. |
