Structured peer-to-peer (P2P) overlay networks like Distributed Hash Tables (DHTs) map data items to the network based on a consistent hashing function. Such mapping for data distribution has an inherent load balance problem. Thus, a load balancing mechanism is an indispensable part of a structured P2P overlay network for high performance. The rapid development of P2P systems has posed challeng...

The interesting properties of P2P systems (high availability despite peer volatility, support for heterogeneous architectures, high scalability, etc.) make them attractive for distributed computing. However, conducting large-scale experiments with these systems arises as a major challenge. Simulation allows only to partially model the behavior of P2P prototypes. Experiments on real testbeds enc...

Current workflow management systems are under dynamic evolution and tend to move to distributed business processes. Software agents and Peerto-Peer (P2P) technology are being recognized as a new approach to decentralized workflow management systems. Plugging Multi-agents into P2P workflow management systems can support run-time functions, workflow instance monitoring, adaptability and exception...

P2P systems are increasingly used for efficient, scalable data sharing. Popular applications focus on massive file sharing. However, advanced applications such as online communities (e.g., medical or research communities) need to share private or sensitive data. Currently, in P2P systems, untrusted peers can easily violate data privacy by using data for malicious purposes (e.g., fraudulence, pr...

Large-scale competitive P2P systems are threatened by the noncooperation problem, where peers do not forward queries to potential competitors. While non-cooperation is not a problem in current P2P free file-sharing systems, it is likely to be a problem in such P2P systems as pay-per-transaction file-sharing systems, P2P auctions, and P2P service discovery systems, where peers are in competition...

The utility of Peer-to-Peer (P2P) systems extends far beyond traditional file sharing. This paper provides an overview of how P2P systems are capable of providing robust command and control for Distributed Multi-Agent Systems (DMASs). Specifically, this article presents the evolution of P2P architectures to date by discussing supporting technologies and applicability of each generation of P2P s...

Peer-to-Peer (P2P) networks are defined as a collection of peers that expose client/server functionalities simultaneously. P2P systems, built on top of P2P networks, support information sharing primitives and lookup mechanisms of data objects located on peers. It has been demonstrated that the P2P paradigm is able to efficiently capture models and, above all, dynamics of modern applications, be...

Due to the dual trends of increasing cellular network transmission capacity and coverage as well as improving computational capacity, storage and intelligence of mobile handsets, mobile peer-to-peer (MP2P) networking is emerging an attractive research field in recent years. However, these trends have not been clearly articulated in perspective of both technology and business. In this paper, we ...
