Emerging technologies represent a major innovation that offers significant advances to both private and public organizations. An example of these technologies is the "blockchain", which combines cryptographic mechanisms and peer-to-peer architecture. The importance of these emerging technologies requires the use of evaluation methods in order to understand their contribution and the associated ...

Important research efforts are conducted in the area of search, lookup, and routing, and are even increasing in light of promises and challenges of peer-to-peer (P2P) systems or the semantic web. To organize these areas of concern, this paper proposes an exhaustive two-dimensional design space that structures and classifies current and facilitates future research. In the functional dimension, i...

Peer-to-peer platforms in the realm of the sharing economy, such as Airbnb or BlaBlaCar, have heavily rattled the electronic commerce landscape and are expected to further impact consumer behavior in the future. While trust between the parties involved is of utmost importance in such platform economies, experimental research on this aspect is scarce. In this conceptual paper, we first present a...

Data quality is becoming an increasingly important issue in environments characterized by extensive data replication. Among such environments, this paper focuses on Cooperative Information Systems (CISs), for which it is very important to declare and access quality of data. Indeed, a system in the CIS will not easily exchange data with another system without a knowledge on its quality, and coop...

P2P systems are a natural way of supporting GroupCommunication (GC) applications. Furthermore, their core characteristics (e.g., self-organisation, self-recovery, decentralisation) match particularly well MANET features. For these reasons we developed and tested a simple yet significant GC application on top of different P2P substrates. Our aim is to understand which type of P2P system is more ...
