Study of asymmetric DHT method and load balancing in P2P network
Guoxin Wu · Journal of Communications · 2007
Asymmetric structure P2P-ASP2P was presented for constructing and optimizing P2P network in heterogene-ous environments.ASP2P introduced a compositive proximity metric including parameters such as reliability,bandwidth and latency for selecting neighbors.Neighbor selection algorithm and routing algorithm were both based on this compo-sitive proximity metric.A load balance mechanism was introduced to avoid overload of nodes.Simulations show that ASP2P can fit the heterogeneous networks better.By the simulation results,the average path length in form of hops of random messages was reduced to 50% of that in basic Chord network;the average delay was reduced to 65%,while the overload of fat nodes was effectively controlled.
