Abstract The Earth System Grid Federation (ESGF) is a multi-agency, international
collaboration that aims at developing the software infrastructure needed to facilitate and …

We present WHATSUP, a collaborative filtering system for disseminating news items in a
large-scale dynamic setting with no central authority. WHATSUP constructs an implicit social …

In this paper we propose a novel algorithm called Rank-Based Broadcast (RBB) for
discovery of local resources in mobile P2P networks. With RBB, each moving object …

The theory of regular transformations of finite strings is quite mature with appealing
properties. This class can be equivalently defined using both logic (Monadic second-order …

This paper presents a study on data dissemination in unstructured Peer-to-Peer (P2P)
network overlays. The absence of a structure in unstructured overlays eases the network …

In this paper, we explore a new form of dissemination called Flash Dissemination that
involves dissemination of fixed, rich information to a large number of recipients in as short a …

In this paper, we present a new simulation tool for scale-free networks composed of a high
number of nodes. The tool, based on discrete-event simulation, enables the definition of …

We study the complexity of gossip in an asynchronous, message-passing fault-prone
distributed system. We show that an adaptive adversary can significantly hamper the …

In this paper, we study the complexity of gossip in an asynchronous, message-passing fault-

Complex networks are an important methodology to model several (if not all) aspects of the
real world, in which multiple entities interact, in some way. While many aspects related to …
