A Novel Search Technique in Peer-to-Peer Networks

چکیده
Sufficient uptime is the main concern in a distributed system where there is no centralized organization and control. Therefore searching in P2P file sharing systems is still a big problem due to the high churn rate of nodes. To find a particular piece of data within the network P2P systems explicitly or implicitly provide a lookup mechanism, which largely depends on the availability of nodes. In this paper we propose a stable node based ranking technique by detecting reliable nodes with adequate uptime by nature to ensure efficient searching and un-interruption during the data receiving. We have simulated an unstructured file-sharing environment to evaluate our proposed

A Novel Caching Strategy in Video-on-Demand (VoD) Peer-to-Peer (P2P) Networks Based on Complex Network Theory
The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...

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 کاملCollaborative Load Balancing Scheme for Improving Search Performance in Unstructured P2P Networks
Peer-to-peer structures are becoming more and more popular and an exhilarating new class of groundbreaking, internet-based data management systems. Query load balancing is an important problem for the efficient operation of unstructured P2P networks. The key issue is to identify overloaded peers and reassign their loads to others. This paper proposes a novel mobile agent based two-way load bala...
