This paper describes a novel approach to network management topologies where multiple customized topologies are self-configured, self-optimized, and maintained automatically by the underlying network of elements. An implementation of these self-forming management topologies as developed in the Celtic European research project Madeira is described. The self-forming topologies use peer-to-peer co...

Interactions within Multi-agent systems can be structured in different ways depending on the application scenario and its environmental restrictions. In previous work we have developed a multi-agent system within a Peer-to-Peer (P2P) sharing data network scenario. Its design includes an organisation that structures agents’ interactions and an abstract architecture (2-LAMA) that helps to improve...

A substantial number of massive large-scale applications require scalable underlying network topologies. Nowadays structured Peer-to-Peer overlay networks meet these requirements very well. But there is still a need to decide which of these overlay networks is most suitable for providing the best possible performance for a certain application. This paper describes SimCon a simulation environmen...

Peer-to-peer (P2P) systems have become a popular medium through which to share huge amounts of data. On the basis of network topology, P2P systems are divided into three types: centralized, structured distribution, and unstructured distribution. Unstructured P2P systems such as Gnutella are novel in the sense that they are extensible and reliable. However, as the number of participating nodes i...

We propose a new p2p network topology that reduces bandwidth consumption and provides complete searches by employing a tree hierarchy of indexing nodes that facilitates the search functionality. Each node consists of a cluster of peers to provide fault tolerance and scalability.

As Peer-to-Peer (P2P) networks become popular, there is an emerging need to collect a variety of statistical summary information about the participating nodes. The P2P networks of today lack mechanisms to compute even such basic aggregates as MIN, MAX, SUM, COUNT or AVG. In this paper, we define and study the NODEAGGREGATION problem that is concerned with aggregating data stored at nodes in the...

In mobile ad-hoc peer-to-peer (M-P2P) networks, a large percentage of the mobile peers typically do not provide any service to the network, thereby motivating incentive schemes for enticing non-cooperative mobile peers to provide service. We propose ABIDE, a novel bid-based economic incentive model for enticing non-cooperative mobile peers to provide service in M-P2P networks. The main contribu...

content discovery is one of the fundamental issues that determines the architecture and performance of content distribution networks based on peer-to-peer (p2p) networks. to administrate the costs and discoveries, peers of a p2p network communicate with each other by one or more overlay layers. the condition of node’s relations in overlay networks, have a great impact in efficiency of networks....
