Dynamic Self-management of Autonomic Systems: The Reputation, Quality and Credibility (RQC) Scheme [chapter]

Anurag Garg, Roberto Battiti, Gianni Costanzi
2005 Lecture Notes in Computer Science  
In this paper, we present a feedback-based system for managing trust and detecting malicious behavior in autonomically behaving networks.  ...  The two crucial insights that motivate our work are the notion of quality of a trust rating and the recognition as separate entities of the trust placed in a node and of the trust placed in the recommendations  ...  Introduction Autonomic systems aim at incorporating methods to monitor their dynamic behavior and to react in automated ways, aiming at self-management and self-improvement.  ...

Reputation management: experiments on the robustness of ROCQ

A. Garg, R. Battiti, R. Cascella
Proceedings Autonomous Decentralized Systems, 2005. ISADS 2005.  
In this paper, we demonstrate that ROCQ is robust against churn and also examine the effect of credibility and quality on the performance of the scheme.  ...  We present new experiments conducted with the ROCQ scheme, a reputation-based trust management system that computes the trustworthiness of peers on the basis of transaction-based feedback.  ...  Figure 1 .Figure 2 . 12 Comparison of the RQC Scheme with the Aberer-Despotovic Scheme with Malicious in the Base System Only Comparison of the RQC Scheme with the Aberer-Despotovic Scheme with Maliciousness  ...

Reputation Management for Collaborative Content Distribution

A. Garg, R. Cascella
Sixth IEEE International Symposium on a World of Wireless Mobile and Multimedia Networks  
ROCQ (Reputation, Opinion, Credibility and Quality), uses feedback from past interactions between nodes to create node reputations.  ...  We propose a reputation-based trust management system, ROCQ, to reduce inauthentic and corrupted file transfers in end-user collaborative content-distribution systems.  ...  Introduction Autonomic content distribution systems need to to be self-managing and self-healing in order to respond autonomically to the users' requests and to changes in the network.  ...

The Perceptions of the Impact of Social Capital on Expatriate Work Well-Being in the Resources Sector in Indonesia

Harum Apriyanti, University, My, Kate Hutchings, Ruth McPhail
This is undertaken through examining the perceptions of expatriates, spouses, and HR managers.  ...  In the current research, perceptions of work well-being, and the perceptions of the impact of social capital on it, are also examined with respect to whether they differ across expatriate employees in  ...  In the social cognitive view, self-efficacy is seen as a dynamic set of self-beliefs that are exclusive to particular performance domains and implies a complex interaction with another person, behaviour  ...
