Relations between friends are also colored by the overwhelming fear of gossip, so that sharing a confidence becomes a risky act. I was once drinking with some young men in a neighborhood bar.  ...  After a few rounds of drinks, one of the friends, named Antonio, politely excused himself and began to leave the bar. On his way out, he motioned surreptitiously for me to follow.  ... 

On tracking freeriders in gossip protocols

Rachid Guerraoui, Kevin Huguenin, Anne-Marie Kermarrec, Maxime Monod
2009 2009 IEEE Ninth International Conference on Peer-to-Peer Computing  
In this paper, we discuss the possibility of using accountability to secure gossip-based dissemination protocols based on asymmetric exchanges.  ...  The fact that gossip protocols are dynamic and randomized makes our approach robust against collusion and alleviates the need for cryptography.  ...  First, BAR Gossip makes intensive use of both symmetric and asymmetric cryptography.  ...

Issues of Implementing Random Walk and Gossip Based Resource Discovery Protocols in P2P MANETs & Suggestions for Improvement

Ajay Arunachalam, Ohm Sornil
2015 Procedia Computer Science  
This article evaluates classic flooding, random walk and gossip based resource discovery algorithms under mobile peer-to-peer (MP2P) networks and studied their performance.  ...  The following bar chart shows the comparative performance of the classic flooding, the random walk and the gossip based resource discovery protocols in terms of network routing load.  ...  The standard random walk and the standard gossip perform poorly. The following bar chart shows the comparative performance of the traditional search methods in terms of network bandwidth/throughput.  ...

Gossip as an alternative for direct observation in games of indirect reciprocity

R. D. Sommerfeld, H.-J. Krambeck, D. Semmann, M. Milinski
2007 Proceedings of the National Academy of Sciences of the United States of America  
This empirical study (with 14 groups of nine students each) focuses on the composition of gossip, information transfer by gossip, and the behavior based on gossip information.  ...  Furthermore, gossip about cooperative individuals is more positive than gossip about uncooperative individuals, gossip comments transmit social information successfully, and cooperation levels are higher  ...  (ϩ, dark bar) or negative (Ϫ, light bar) gossip pretendedly being about the same decisions (case IIA inFig. 1).  ...

GossipTrust for Fast Reputation Aggregation in Peer-to-Peer Networks

Runfang Zhou, Kai Hwang, Min Cai
2008 IEEE Transactions on Knowledge and Data Engineering  
The gossip-based protocol is designed to tolerate dynamic peer joining and departure, as well as to avoid possible peer collusions. The scheme has a considerably low gossiping message overhead, i.e.  ...  Randomized gossiping with effective use of power nodes enables fast aggregation and fast dissemination of global scores in O(log 2 n) time steps, where n is the network size.  ...  For 20,000 jobs, the gray shaded bar is about 30% higher than the white bar. For 1000,000 jobs, the GossipTrust outperforms the NoTrust system by 50%.  ...
