【摘要】 定位技术的快速发展使得获取位置信息的成本越来越低,此外利用位置信息可以有效降低路由开销,因此,基于位置信息的路由算法逐渐成为自组织网络路由算法的热点。在对现有基于位置信息的路由算法进行分析的基础上,对单播路由算法中贪婪转发算法及空洞处理算法进行研究,并对基于位置信息的多播路由算法及地理区域路由算法作了简要概述。更多还原

【Abstract】 The cost of obtaining position information getting lower and lower as the rapid development of network technology,moreover,utilizing the position information can effectively reduce the routing overhead,consequently the position-based routing algorithm becomes one of the popular researching topics.Based on the analysis of current position-based routing algorithms,this paper summarizes research on the current greedy forwarding algorithm and void handling algorithms,and research on the position-based multicast and GeoCast are also presented.更多还原
