Range query in DHT based P2P network is a hot topic in recent researches. The hashing function in DHT protocols makes the data hard to keep their original order relationship. Hence range queries for such networks become difficult. This paper presents the design of Yarqs-a new schema to achieve range queries in DHT based P2P networks. By using the inherent characteristics of DHT based networks, Yarqs...
