【摘要】 确定网络节点位置是互联网中一种重要的应用服务。目前主流的确定网络节点位置的系统都不易获取且不具有实时性,给出的节点位置不够准确。提出1种基于网络坐标的节点地理位置预测系统,利用少数地标节点的位置信息,并结合相应的网络坐标,对网络当中任意节点的地理位置进行实时地预测。通过在Internet网络当中开展实验,进一步验证了该系统的可行性和准确性。结果表明,在实验开展的范围内,系统能够准确的预测节点的地理位置。更多还原

【Abstract】 Locations of the hosts are very important for many Internet applications.However,this location information is hard to obtain in existing service,either not real time or lack of accuracy.In this paper,a Network Coordinate based host locating system is presented,in which,hosts’ geographic positions are derived from their network coordinates and geographic information of the landmarks.Our extensive experiments on PlanetLab show that our system can predict hosts’ geographic positions accurately.更多还原
