Optimal scheduling of peer-to-peer file dissemination
Journal of Scheduling (KLU-JOSH), Volume 11, Issue 2April 2008, Pages 105–120https://doi.org/10.1007/s10951-007-0017-9Peer-to-peer (P2P) overlay networks such as BitTorrent and Avalanche are increasingly used for disseminating potentially large files from a server to many end users via the Internet. The key idea is to divide the file into many equally-sized parts and ...

Analysis of a reputation system for Mobile Ad-Hoc Networks with liars
Performance Evaluation (PEVA), Volume 65, Issue 3-4March, 2008, Pages 212–226https://doi.org/10.1016/j.peva.2007.05.004The application of decentralized reputation systems is a promising approach to ensure cooperation and fairness, as well as to address random failures and malicious attacks in Mobile Ad-Hoc Networks. However, they are potentially vulnerable to liars. ...

A Generic Mean Field Convergence Result for Systems of Interacting Objects
QEST '07: Proceedings of the Fourth International Conference on Quantitative Evaluation of SystemsSeptember 2007, Pages 3–18https://doi.org/10.1109/QEST.2007.3We consider a model for interacting objects, where the evolution of each object is given by a finite state Markov chain, whose transition matrix depends on the present and the past of the distribution of states of all objects. This is a general model of ...

Analysis of peer-to-peer file dissemination
ACM SIGMETRICS Performance Evaluation Review (SIGMETRICS), Volume 34, Issue 3December 2006, Pages 12–14https://doi.org/10.1145/1215956.1215963In recent years, overlay networks have proven a popular way of disseminating potentially large files from a single server S to a potentially large group of N end users via the Internet. A number of algorithms and protocols have been suggested, ...

Reputation in self-organized communication systems and beyond
Interperf '06: Proceedings from the 2006 workshop on Interdisciplinary systems approach in performance evaluation and design of computer & communications sytemsOctober 2006, Pages 3–eshttps://doi.org/10.1145/1190326.1190328Efficiently handling reputation is important in dealing with free-riding, malicious attacks and random failures in self-organized communication systems. At the same time, work in this context is often found to be relevant in many other disciplines, in ...

Analysis of peer-to-peer file dissemination amongst users of different upload capacities
ACM SIGMETRICS Performance Evaluation Review (SIGMETRICS), Volume 34, Issue 2September 2006, Pages 5–6https://doi.org/10.1145/1168134.1168138In recent years, overlay networks have proven an effective way of disseminating a file from a single source to a group of end users via the Internet. A number of algorithms and protocols have been suggested, implemented and studied. In particular, much ...

Analysis of a Reputation System for Mobile Ad-Hoc Networks with Liars
WIOPT '05: Proceedings of the Third International Symposium on Modeling and Optimization in Mobile, Ad Hoc, and Wireless NetworksApril 2005, Pages 41–46https://doi.org/10.1109/WIOPT.2005.13Using decentralized reputation systems is a promising approach to ensuring cooperation and fairness in Mobile Ad-Hoc Networks. However, they are vulnerable to liars and robustness has not been analyzed in detail. With our work, we provide a first step to ...
