This research work explains different aspects of PeerSim simulator used to create nodes and simulate peer to peer overlay network topology generation protocols. PeerSimhas been tested over various protocols specifically designed to work with a heterogeneous environment and its efficiency and scalability is evaluated considering different properties of the nodes and network. These protocols are used...
In this paper, we investigate the mobile P2P file-sharing problem, and proposed a mobile P2P content distribution architecture. Due to mobile specific influence factors, a hybrid architecture has been employed. We assume that the P2P mobile terminal can publish, index and retrieve resources on the Index Server, and collect the real-time state and cache content resource through Resource Management...
One of the essential problems in unstructured peer-to-peer (P2P) network is enhancing the efficiency of resource retrieval. Previous researches either have poor response speed, or generate too much network overhead. In order to reduce the traffic load and improve the availability of the sharing resources in unstructured P2P networks, a key-peers based topology control mechanism is presented in this...
Finding related resources is important for assisting resource retrieval and recommendation in the P2P network. This paper proposes a method for discovering such clusters of related resources, which are called resource communities. Graph mining approach is applicable here. Discovering communities is based on bipartite graph which is composed of resources and keywords. The data is extracted from the...
Due to the vehicle's movement and inherent characteristics of wireless channel, how to discover and retrieve the required contents has become a challenging issue in a hybrid network including vehicular ad hoc networks (VANETs) and the Internet. In this paper, we propose a social cluster-based P2P framework that estimates similarity and connection condition among peers to provide mobile peers efficient...
Resource retrieval is a key element for P2P networks. In this paper we focus on unstructured peer-to-peer networks and present an approach for resources retrieval called DV-Flood. This approach aims to minimize lookup and get delay. The architecture of our proposed model is organized as a several clusters connected through gateways (leader node). Each cluster is represented by a super node (leader)...
