'Dominating-set-based' searching in peer-to-peer networks

Dominating-Set-Based Searching in Peer-to-Peer Networks

The peer-to-peer network for sharing information and data through direct exchange has emerged rapidly in recent years. The searching problem is a basic issue that addresses the question “Where is X”. Breadth-first search, the basic searching mechanism used in Gnutella networks [7], floods the networks to maximize the return results. Depth-first search used in Freenet [6] retrieves popular files...

Searching Techniques in Peer-to-Peer Networks

This chapter provides a survey of major searching techniques in peer-to-peer (P2P) networks. We first introduce the concept of P2P networks and the methods for classifying different P2P networks. Next, we discuss various searching techniques in unstructured P2P systems, strictly structured P2P systems, and loosely structured P2P systems. The strengths and weaknesses of these techniques are high...

Secure and Privacy-Aware Searching in Peer-to-Peer Networks

The existing peer-to-peer networks have several problems such as fake content distribution, free riding, white-washing and poor search scalability, lack of a robust trust model and absence of user privacy protection mechanism. Although, several trust management and semantic community-based mechanisms for combating free riding and distribution of malicious contents have been proposed by some res...

Searching Behavior in Peer-to-Peer Communities

The focus of this paper is the searching behavior in Peer-to-Peer (P2P) communities and in that context, will discuss potential for enhancement of the P2P protocol using searching behavior. Due to excessive network traffic, network scalability is a major P2P problem. The purpose of this paper is to study searching behavior by using log files and subsequently, will propose solutions to reduce th...
