摘要
为降低导航方法对移动目标配置的要求,并为移动目标提供在线式导航,提出一种基于无线传感器网络的移动目标导航方法。该方法使用无线传感器网络信息进行导航环境描述,建立影响移动目标前进的多种环境因素的势场模型,结合最短路径与最安全路径,提出一种基于代价的导航决策方法,根据导航代价最小的原则,进行移动目标的导航.分析表明,该导航算法能够满足在线导航的要求,实现移动目标的高精度导航.
In order to decrease the deployment demand for mobile object and give online navigation, we proposed a new navigation algorithm for mobile object based on wireless sensor networks. It firstly built an environment description model with wireless sensor networks and potential field models of many environment facts impacting the movement of mobile object. Then combining the minimal path and the safest path, we proposed a navigation cost method for mobile object＇s navigation. It makes know by analysis that the new algorithm can achieve online navigation and highly precise navigation for mobile object.
