Shp: a Hierarchical Protocol to Improve Performance of Peer-to-peer Systems

چکیده
Extensive application of Peer-to-Peer systems demands an effective solution for efficient query processing, handling of churn rate, load balancing and maintenance of healthy arrangement of nodes for the improved response of the system. Several key based systems offer an efficient solution for query processing but suffer from transient node population. We present a structured hierarchical Peer-to-Peer system to reduce overhead caused by churn rate. The simulation result shows better performance than existing structured systems while executes point query and range query.

TAC: A Topology-Aware Chord-based Peer-to-Peer Network
Among structured Peer-to-Peer systems, Chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. However, Chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing late...
متن کاملA Genetic Programming-based trust model for P2P Networks
Abstract— Peer-to-Peer ( P2P ) systems have been the center of attention in recent years due to their advantage . Since each node in such networks can act both as a service provider and as a client , they are subject to different attacks . Therefore it is vital to manage confidence for these vulnerable environments in order to eliminate unsafe peers . This paper investigates the use of genetic ...
متن کاملDisTriB: Distributed Trust Management Model Based on Gossip Learning and Bayesian Networks in Collaborative Computing Systems
The interactions among peers in Peer-to-Peer systems as a distributed collaborative system are based on asynchronous and unreliable communications. Trust is an essential and facilitating component in these interactions specially in such uncertain environments. Various attacks are possible due to large-scale nature and openness of these systems that affects the trust. Peers has not enough inform...

متن کاملImpact of Early Clinical Exposure by Peer assisted learning on Clinical Performance among First Year Nursing Students
Introduction: Clinical education is the heart of nursing education. One of the challenges of clinical education is the lack of clarity of the relationship between theoretical education and clinical training. On the other hand, peer teaching can be a supplementary tool in clinical skills training. Therefore, this study examine the effect of early clinical exposure in peer assisted learning on th...
