A Sector-Based Routing Model over Structured Peer-to-Peer Networks

摘要

In a structured peer-to-peer network, frequent join and leave of peer members cause huge maintenance overhead. To deal with this churn problem, we proposed a sector-based routing model (SBRM). The key space is divided into several sectors and each sector has a peer member acting as the relay proxy of the sector. Then the cost of join and leave can be greatly reduced. In this paper we choose Chord as the underlying structured network and perform a series of simulation. Analysis and simulation results show that SBRM achieve lower communication cost when a member joined or left the system, and message routing path length is also shortened.
