The efficiency of a Peer-to-Peer file sharing overlay is measured in terms of the scalability and versatility of its object lookup strategy. In these networks peers carry out distributed query relaying to discover the service providers. Existing lookup mechanisms like flooding and random walks in unstructured P2P overlays create huge communication overhead and increased response time. In this w...

With the population of network usage, it is possible to connect home appliances with each other. The basic demand is to connect home appliances easily with less user intervening and home network is an complex environment which comprises several network architecture including ethernet, wireless network, or power-line etc.. Therefore, integrating heterogeneous environment in home network to reduc...

Peer-to-Peer (p2p), as an emerging technology, is exerting huge influence on various application scenarios. Meanwhile, agents, assisting applications in traditional paradigm with intelligent ways, have to fit in this new trend. Observing the potential benefits of combining agent and p2p technologies, we propose a novel platform-“A-peer” in our approach. A-peer is an agent based secure p2p platf...

Peer-to-peer (P2P) systems are widely used to exchange content over the Internet. Knowledge of pedophile activity in such networks remains limited, despite having important social consequences. Moreover, though there are different P2P systems in use, previous academic works on this topic focused on one system at a time and their results are not directly comparable. We design a methodology for c...

General networks such as Internet are complex heterogeneous networks, which are constructed by many different organizations, and so become non-effective ones. Therefore one constructed a level of software over networks which is called overlay or virtual topology. In this paper we present principle of symmetry for general network topology by using Cayley graph models and show its necessity to im...

Modeling peer-to-peer (P2P) networks is a challenge for P2P researchers. In this paper, we provide a detailed analysis of large-scale hybrid P2P overlay network topology, using Gnutella as a case study. First, we re-examine the power-law distributions of the Gnutella network discovered by previous researchers. Our results show that the current Gnutella network deviates from the earlier power-la...
