Self-organized networks such as mobile ad-hoc, Internet-based peer-to-peer, wireless mesh and Fourth Generation (4G) Wireless networks depend on cooperation of nodes. Reputation systems help nodes decide with whom to cooperate and which nodes to avoid. The ...
Peer-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 then ...
Self-organized networks require some mechanism to ensure cooperation and fairness. A promising approach is the use of decentralized reputation systems. However, their vulnerability to liars has not yet been analyzed in detail. In this paper, we provide a r ...
The 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. With o ...
Reputation systems are widely and successfully used in centralized scenarios. Will they work equally well, however, in decentralized scenarios such as Internet-based peer-to-peer systems and mobile ad hoc networks? ...
