The research on distributed storage mechanism used in clustered opportunistic network

This paper presents a distributed storage mechanism to achieve the goal of data sharing based on clustered opportunistic network. The proposed mechanism includes two parts. The first part presents the list of the stored information based on models of different kinds of nodes in the cluster and the second part are the decision algorithm and configuration process for administrative behavior such as addition and deletion of data replica based on the list mentioned in the first part. The simulation result shows that the proposed mechanism can adapt well to the poor connectivity of the normal nodes in opportunistic network, thus achieving data sharing more efficiently.
