Emerging collaborative Peer-to-Peer (P2P) systems require discovery and utilization of diverse, multiattribute, distributed, and dynamic groups of resources to achieve greater tasks beyond conventional file and processor cycle sharing. Collaborations involving application specific resources and dynamic quality of service goals are stressing current P2P architectures. Salient features and desira...

This paper introduces a client-server suite called DCEZ (easy distributed computing), which provides a readily configurable and easy to use network distributed computing framework. The suite will allow users to easily operate a distributed computing environment and solve real problems with a hybrid peer–to-peer (P2P) grid. It is anticipated that this tool will be most useful in a pedagogical se...

A growing number of collaborative applications are being built on top of Peer-to-Peer (P2P) networks which provide scalability and support dynamic behavior. However, the distributed algorithms used by these applications typically introduce multiple communications and interactions between nodes. This is because P2P networks are constructed independently of the underlying topology, which may caus...

Peer-to-peer (P2P) computing offers new opportunities for building highly distributed data systems. Unlike client-server computing, P2P can operate without central coordination and offer important advantages such as a very dynamic environment where peers can join and leave the network at any time; direct and fast communication between peers, and scale up to large number of peers. However, most ...

A peerto-peer (P2P) network is a distributed system in which peers employ distributed resources to perform a critical function in a decentralized fashion. As the peers participating in unstructured networks interconnect randomly, they rely on flooding query messages to discover objects of interest and thus introduce remarkable network traffic. The resultant networks may not perform searches eff...

Peer-to-Peer infrastructures are emerging as one of the important data management infrastructures in the World Wide Web. So far, however, most work has focused on simple P2P networks which tackle efficient query distribution to a large set of peers but assume that each query can be answered completely at each peer. For queries which need data from more than one peer to be executed this is clear...

File sharing in networks is generally achieved using Peer-to-Peer (P2P) applications. Structured P2P approaches are widely used in adhoc networks due to its distributed and scalability features. Efficient mechanisms are required to handle the huge amount of data distributed to all peers. The intrinsic characteristics of P2P system makes for easier content distribution when compared to client-se...

Mobile computing is a revolutionary technology, born as a result of remarkable advance in the development of computer hardware and wireless communication. It enables us to access information anytime and anywhere even in the absence of physical network connection. More recently, there has been increasing interest in introducing ad hoc network into mobile computing, resulting in a new distributed...

Distributed computing often needs to cope with information integration challenges. Up to now, several models have been proposed for information integration in heterogeneous, distributed and (loosely) dynamic environments. Nevertheless, in network environments where the actors and their information sources are characterized by high dynamism and non permanent connections, the traditional approach...
