An common difficulty in structured P2P networks is caused by the dynamic membership of nodes (churn). This results in constant reorganization of overlay topology. The objective of this paper is to handle churn in P2P networks by a flexible cluster-based protocol. In our protocol, a cluster of nodes work together to achieve efficient greedy routing and the size of each cluster varies between an upper...
In large scale MANETs, centerless clustering algorithms need to reduce topology and routing maintenance overheads by constructing a stable hierarchical topology. So attention should be focused on topologypsilas stability. At present, attentions are paid to the inner cluster topologypsilas stability, but the intercluster topologypsilas stability is neglected. Therefore, we propose a fully distributed...
