As computer networks increase in size, become more heterogeneous and span greater
geographic distances, applications must be designed to cope with the very large scale, poor …

Gossip-based communication protocols are appealing in large-scale distributed applications
such as information dissemination, aggregation, and overlay topology management. This …

In recent years, the gossip-based communication model in large-scale distributed systems
has become a general paradigm with important applications which include information …

Recent developments in information technology have brought about important changes in
distributed computing. New environments such as massively large-scale, wide-area …

In this paper, we focus on the problem of maintaining significant levels of cooperation in
peer-to-peer (P2P) networks of selfish adaptive peers. We propose a simple algorithm that …

We present a constructive authorization logic where the meanings of connectives are
defined by their associated inference rules. This ensures that the logical reading of access …

Aggregation refers to a set of functions that provide global information about a distributed
system. These junctions operate on numeric values distributed over the system and can be …

Structured peer-to-peer overlay networks are now an established paradigm for
implementing a wide range of distributed services. While the problem of maintaining these …

Components in a decentralised system are faced with uncertainty as how to best adapt to a
changing environment to maintain or optimise system performance. How can individual …

Many peer-to-peer (P2P) applications benefit from node specialization: for example, the use
of supernodes, the semantic clustering of media files or the distribution of different …
