P2P Networks and Distributed Systems

Peer-to-peer networks are distributed systems, where all participating entities both provide and utilize services to/from each other. Our research in P2P covers both unstructured and structured architectures (Distributed Hash Tables - DHTs).


XOR Object Store (or XOROS for short) is a structured peer-to-peer system (Distributed Hash Table) designed with data updates in mind. Most current DHT implementations require that data values, once written, should not be modified. XOROS addresses this issue, by incorporating related distributed mutex and Byzantine-tolerant communication protocols at the peer-to-peer level.


We are developing a peer-to-peer filesystem for Grid4all, an EU funded research project that proposes a democratic grid, based on peer-to-peer technology.

HiPPIS Project

This is a system where multidimensional data organized in concept hierarchies are stored, indexed and queried in a fully distributed environment.


In this project, we describe a distributed algorithm for adaptive load balancing in systems that support range queries. We address the issue of uneven load distribution among the peers that occurs when nodes index items of varying popularity.
