Optimal Placement Strategy of DHT-based Systems to Minimize Lookup Latency

摘要：

　　This paper proposes an optimal placement strategy of physical nodes of DHT-based systems to minimize the lookup latency and improve the throughput of system.The main idea of our approach is to create a new hierarchy named link space between logical space and physical space of DHT overlay.We firstly give an assignment of link space and then present the optimal placement strategy of placing physical nodes on it based on the given lookup traffic matrix.At last,we use genetic algorithm to solve the optimization problem.
