Feature-related Node Address and Replica Distribution over Structured P2P Networks

Abstract: In the traditional structured P2P network,node identifications are generated randomly or based on order.There is a lack of correlation between the features such as node distribution,node location,and safety.The phenomenon of "wrong correlation" cannot be dealt with effectively,and there is a risk of data corruption.A new node addressing method was proposed in this paper,together with its correlated replica distribution algorithm.By combining characteristic information such as location and security of nodes into node identification,the nodes can be distributed according to their features.According to these features,nodes can be avoided or approached during the replica distribution procedure.Based on this,problems such as "wrong correlation" are solved,and the distribution efficiency is improved.The node distribution and backup nodes selection result after improvement were given out in the emulation experiment,which shows the effectiveness of the method.
