  • Exploiting semantic proximity in peer-to-peer content searching  
  • by Spyros Voulgaris — 2004 — In 10th International Workshop on Future Trends in Distributed Computing Systems (FTDCS 2004), Suzhu
  • …A lot of recent work has dealt with improving performance of content searching in peer-to-peer file sharing systems. In this paper we attack this problem by modifying the overlay topology describing the peer relations in the system. More precisely, we create a semantic overlay, linking nodes that ar…

  • An Epidemic Protocol for Managing Routing Tables in Very Large Peer-To-Peer  
  • by Spyros Voulgaris, Maarten Van Steen — 2003 — In Proceedings of the 14th IFIP/IEEE International Workshop on Distributed Systems: Operations and Management, (DSOM 2003), number 2867 in Lecture Notes in Computer Science
  • …Building self-maintained overlay networks for message routing has recently attracted significant research interest [5--9]. All suggested solutions have a common goal: To build and maintain structures (routing tables) that can be used to route messages. Several of the proposed algorithms focus on …

  • Epidemic-style Management of Semantic Overlays for Content-Based Searching  
  • by Spyros Voulgaris, Maarten Van Steen — 2005 — In EuroPar
  • …Abstract. A lot of recent research on content-based P2P searching for filesharing applications has focused on exploiting semantic relations between peers to facilitate searching. To the best of our knowledge, all methods proposed to date suggest reactive ways to seize peers ’ semantic relations. Tha…

  • Gossip-Based Clock Synchronization for Large Decentralized Systems  
  • by Konrad Iwanicki, Maarten Van Steen, Spyros Voulgaris — 2006 — In Proceedings of the Second IEEE International Workshop on Self-Managed Networks, Systems and Services (SelfMan 2006
  • …Numerous large-scale decentralized systems assume loosely synchronized clocks. Existing time protocols have not been designed for deployment in such systems, since they are complex and require manual configuration. We present the Gossiping Time Protocol (GTP), a completely self-managing epidemic tim…

  • Epidemic-style monitoring in large-scale wireless sensor networks  
  • by Daniela Gavidia, Spyros Voulgaris, Maarten Van Steen — 2005 — IR-CS012.05, Vrije Universiteit
  • …This paper focuses on monitoring the state of the nodes in a wireless sensor network where the nodes are unaware of the location of the monitoring node. We introduce an epidemic protocol designed to propagate the state of the nodes in a simple, yet effective manner. The nodes in the network communic…

  • Transparent Server Shutdown in a Wide-Area Location Service  
  • by Spyros Voulgaris, Aline Baggio, Gerco Ballintijn, Maarten Van Steen
  • …A location service provides the means of keeping location info on objects. In a Wide Area Network, the location service is often a critical part and is likely to be implemented as a collection of servers distributed across multiple hosts. In such a collection adding and removing servers is complicat…

  • Epidemic-style Monitoring in Large-Scale Sensor Networks  
  • by Daniela Gavidia, Spyros Voulgaris, Maarten Van Steen — 2005
  • …As wireless sensor nodes become more powerful, affordable and compact, the possibility of deploying massive numbers of networked nodes for various purposes becomes more and more attractive. Large-scale networks of wireless sensor nodes constructed “on the fly ” could easily monitor environment varia…

  • CYCLON: Inexpensive Membership Management for Unstructured P2P Overlays  
  • by Spyros Voulgaris, Daniela Gavidia, Maarten Van Steen — 2005 — Journal of Network and Systems Management
  • …Unstructured overlays form an important class of peer-to-peer networks, notably when content-based searching is at stake. The construction of these overlays, which is essentially a membership management issue, is crucial. Ideally, the resulting overlays should have low diameter and be resilient to m…

  • A Robust and Scalable Peer-to-Peer Gossiping Protocol  
  • by Spyros Voulgaris, Márk Jelasity, Maarten Van Steen — 2003 — In 2nd Int’l Workshop Agents and Peer-toPeer Computing, LNCS 2872
  • …Abstract. The newscast model is a general approach for communication in large agent-based distributed systems. The two basic services— membership management and information dissemination—are implemented by the same epidemic-style protocol. In this paper we present the newscast model and report on ex…
