Distributed algorithms for stable and secure network coordinates
Guohui Wang, T. S. Eugene Ng · 2008
Since its inception, the concept of network coordinates has been proposed to solve a wide variety of problems such as overlay optimization, network routing, network localization, and network modeling. However, two practical problems significantly limit the applications of network coordinates today. First, how can network coordinates be stabilized without losing accuracy so that they can be cached by applications? Second, how can network coordinates be secured such that legitimate nodes' coordinates are not impacted by misbehaving nodes? Although these problems have been discussed extensively, solving them in decentralized network coordinates systems remains an open problem.
