一种基于UWB穿戴式网络的调度算法

A Dynamic Scheduling Algorithm Based on UWB in Wearable Network

可穿戴式计算机是近几年的一个研究热点,穿戴式网络多个节点之间的协调通信一直是影响穿戴式计算机发展的一个重要原因,因此有必要对穿戴式网络通信进行优化。文中介绍了可穿戴式计算机以及穿戴式网络。论述了穿戴式网络中常用的几种网络技术的优缺点。然后重点解析了UWB(Ultra-Wide Band)的结构模型,以及UWB通信机制,在UWB通信机制的基础上引入了动态调度的思想,由此引出具有优先级的动态UWB网络调度算法。此调度算法能够很好地协调穿戴式网络节点之前的通信,有利于推进可穿戴式计算机的发展。

Wearable computer is a hot research topic in recent years; however multiple nodes communication between each other in weara- ble network has been the important impact of the development of wearable computer. So it is necessary to improve the wearable network communication. The wearable computers and wearable network are introduced, discussing several kinds of network technologies which are frequently used in the wearable network. And then introduced the UWB （Ultra-Wide Band） structure model, and UWB communication mechanism, and a dynamic scheduling algorithm based on UWB in wearable network is introduced which has priority in the scheduling al- gorithm. This scheduling algorithm can improve the performance between each nodes in wearable network and help promote the develop- ment of wearable computer.
