论文摘要
IP地理位置是许多应用领域（例如内容交付网络，有针对性的广告和执法部门）的关键推动力。因此，需要提高精度以提高服务质量。尽管IP地理位置是一个持续的研究领域，但这仍然是一项具有挑战性的任务，而仅通过使用主动延迟测量结果才能实现良好的结果。本文提出了一种新的方法，可以找到优化的地标位置，用于主动探测并引入改进的位置估计。由于合理的地标选择对于高度准确的本地化服务很重要，因此目标是在基础架构和跳跃数方面找到靠近目标的地标。当前的技术提供了有关解决此问题以及使用不精确模型的信息。我们在现实环境中证明了我们的方法的可用性。优化的地标选择和高级调制的组合可以提高IP地理位置的精度。
IP Geolocation is a key enabler for many areas of application like Content Delivery Networks, targeted advertisement and law enforcement. Therefore, an increased accuracy is needed to improve service quality. Although IP Geolocation is an ongoing field of research for over one decade, it is still a challenging task, whereas good results are only achieved by the use of active latency measurements. This paper presents an novel approach to find optimized Landmarks positions which are used for active probing and introduce an improved location estimation. Since a reasonable Landmark selection is important for a highly accurate localization service, the goal is to find Landmarks close to the target with respect to the infrastructure and hop count. Current techniques provide less information about solving this problem as well as are using imprecise models. We demonstrate the usability of our approach in a real-world environment. The combination of an optimized Landmark selection and advanced modulation results in an improved accuracy of IP Geolocation.
