In a structured peer-to-peer (p2p) network, key based routing algorithms are used for searching and locating resources in the network. For dynamic and scalable behavior these algorithms suffer from high overhead to maintain large state information of nodes and to keep them up-to-date. To deal with this problem, a Sub-ring Based Chord model and a lookup algorithm are proposed. The lookup process keeps...
In DHT based P2P networks, the heterogeneity of node capacity and the skewness in query pattern could result in lookup load imbalance. Indegree adjustment is an effective, light-weighted and heterogeneity-aware approach to balance lookup traffic in local area, but not globally. In this paper we present a hybrid algorithm combining in degree adjustment and virtual server (VS) approaches to address...
Distributed hash tables (DHTs) with O(1) lookup performance strive to propagate membership changes through efficient distribution mechanism to allow each node in the peer-to-peer network maintains accurate routing tables with complete membership information. We present UnoHop, an efficient DHT algorithm with O(1) lookup performance. UnoHop uses an efficient algorithm to propagate membership events...
