RNBG: A Ranking Nodes Based IP Geolocation Method

摘要

IP geolocation technology is widely adopted in network security, privacy protection, online advertising, etc. However, existing IP geolocation methods are vulnerable to delay inflation, which reduces their reliability and applicability, especially in weakly connected networks. To solve this problem, a ranking nodes based IP geolocation method (RNBG) is proposed. RNBG leverages the scale-free nature of complex networks to find a few important and stable nodes in networks. And then these nodes are used in the geolocation of IPs in different regions. Experimental results in China and the US show that RNBG can achieve high accuracy even in weakly connected network. Compared with typical methods, the geolocation accuracy is increased by 2.60%-14.27%, up to 97.55%.
