This paper presents a speculative Byzantine algorithm base on Zyzzyva which has high performance for applying to peer to peer (P2P). We adopt a hybrid P2P system with monitor node to improve the performance of pure P2P system.
Peer to peer (P2P) online game systems have garnered attention recently. This paper presents an online game protocol based on the lockstep protocol and the Byzantine agreement algorithm. The former prevents dishonest actions called time-cheats in a peer to peer (P2P) network. The latter disables Byzantine cheats, with actions resembling the Byzantine fault. Using this protocol, a game can be continued...
In Grid Computing, harnessing the power of idle resources in a distributed environment is one of the important features. However, to fully benefit from this computing model, an appropriated resource allocation method needs to be carefully chosen and deployed. A number of studies have been done on this area and one of the promising approaches is to adopt a marketing scheme called the auction model,...
Large scale volunteer computing has been proved to be an efficient mechanism to solve the complicated problems. Specifically, in such a system, thousands of idle computers on the network are organized to finish a series of tasks dispatched by a central server. However, this computing model is vulnerable to attack from malicious peers returning incorrect results, since it is impossible to check each...
This paper proposes a P2P-based dynamic load balancing mechanism to increase the dependability of volunteer computing. The proposed mechanism is incorporated into a volunteer computing middleware, called the Berkeley Open Infrastructure for Network Computing (BOINC). The proposed mechanism provides two additional features: decentralized load balancing and proxy download. The former feature reduces...
