A New Approach for Improving Lookup Efficiency in P2P Networks through Allocating Load Based on Nodes' Strength

摘要

One of the major aims in various existing protocols in P2P (peer-to-peer) networks is load balancing between network nodes. This load is of various types which include processing, storage and traffic load. Most existing protocols try to allocate the existing load equally between the nodes and in doing so they assume that all nodes have equal capability. Super-peer based protocols, through allocating more role and load to stronger nodes, try to increase network efficiency. This is done through the composition of smaller P2P networks within all super-peers and each of the other nodes selects a super-peer as a father through which it does its intended operation in P2P network. However, since the division of nodes into two or more limited clusters may ignore many inter-node differences in a cluster, relative allocation of tasks and load on nodes in a continuous linear way can allocate the existing load much better and more efficiently and can cause a higher efficiency and a faster lookup.
