For the problems of complex queries, load balance and routing efficiency in structured P2P networks based on DHT, a protocol is presented for text retrieval on the basis of Kleinberg small world model. In this protocol, nodes are clustered to support complex query according to the similarity of nodes, and the grouped nodes could adjust their size to balance the load of networks. Routing path length...
The coupling of signaling protocols for mobility management and resource reservation plays an important role to achieve quality-of-service (QoS) in mobile environments. When performing a handover, request and allocation of resources have to be done in the shortest possible time to avoid disruptions for the user service. In this paper, we analyze the effects of node mobility on the interaction between...
A novel load balance technique based on rumor mongering in structured P2P networks is presented in this paper to address the hotspot problem when using DHT P2P networks as the distributed index systems. The basic idea is making use of the periodical topology maintenance communications to piggyback and spread popular information by way of rumor mongering in background. It is shown in the paper that,...
