This paper formulates requirements for anonymous overlay networks for enhancing the privacy of mobile ad hoc network users. Besides, it analyzes existing peer-to-peer based anonymous overlay networks and shows that none of them are compliant with those requirements. Finally, it outlines the ongoing design of an anonymous overlay network intended for mobile ad hoc environments.

We study the interaction between optimal routing overlay and Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) in a single Autonomous System (AS). Our work is motivated in part by the work of Qiu et al [1], in which the interaction between overlay selfish routing and TE is brought up. However, our work is different in that [1] assumes each overlay user controls an infinitesimal amou...

If visualization is more effective when accompanied by narration, why not superimpose visualization on narration? This might result in better transfer of learning. We will present a general framework for such superimposed visualization, called overlay visualization. The objectives for the design of our framework are 1) to separate the application from the visualization; and 2) to separate the s...

This paper presents an overview of the implementation of Application Layer Multicast (ALM) in OverSim, a simulation framework designed specifically for simulating overlay networks. OverSim builds upon the OMNeT++ discrete event simulator. In addition, the paper presents guidelines for further research work based on reliable and Quality of Service (QoS)-aware multicast overlay networks. This res...

This work presents a gossip-based protocol, termed QuickPeer, which builds and maintains latency-aware overlay topologies. Such topologies are useful for several distributed applications, like distributed online gaming, context-aware P2P applications and QoS-aware publish/subscribe systems. The distinctive feature of QuickPeer is that it can manage large scale overlay topologies providing each ...

Multicast Service Overlay Network (MSON) has been recently introduced to address some of the deployment and maintenance problems of IP multicast and application-level multicast. An MSON is essentially a backbone service overlay provisioned by an MSON provider and designed to “multiplex” multiple user overlays. It consists of service nodes or proxies deployed by the provider. The proxies are str...

The ever increasing demand of new applications has led researchers to propose new network architectures that address limitations of the current Internet. Given the rigidity of the Internet today, overlay networks are used to implement such architectures, in the hope of gaining a large user base. Despite sustained efforts to test and deploy new network architectures (on testbeds such as Planetla...

Overlay networks present an interesting challenge for faulttolerant computing. Many overlay networks operate in dynamic environments (e.g. the Internet), where faults are frequent and widespread, and the number of processes in a system may be quite large. Recently, self-stabilizing overlay networks have been presented as a method for managing this complexity. Self-stabilizing overlay networks p...

Overlay networks are becoming widely used for delivering content, since they provide effective and reliable services that are not otherwise available. However, overlay management systems face the challenges of increased complexity and heterogeneity due to the numerous entities that are involved in realizing overlay services. We believe that autonomic management is a key solution for dealing wit...

Current research in peer to peer systems is lacking appropriate environments for simulation and experimentation of large scale overlay services. This has led to a plethora of custom made simulators that waste development resources and hinder fair comparisons between different approaches. In this paper we present a new simulation / experimentation framework for large scale overlay services with ...
