Grid and peer-to-peer technology are widely applied to file sharing system. P2P overlay network topology and search algorithm have always got much attention of researchers. A mismatch between overlay and the Internet infrastructure has critical performance implications in search efficiency. We design a file sharing system named RP(k)C-Grid. It is a hybrid topology overlay network composed of two parts:...
To solve security problems of E-commerce system, this paper proposed a new trust model APR which is based on anticipative perceived risk. The concept of perceived risk was introduced into APR, many kinds of trust factor were taken to calculate the trust value among nodes, and an origination method was provided to integrate direct trust and recommendation trust. Comparing with other trust models, APR...
The Chord protocol is the best known example of implementation of logarithmic complexity routing for structured peer-to-peer networks. Its routing algorithm, however, does not provide an optimal trade-off between the size of the finger table and the average number of hops to reach destination. Lately, a base-k chord appeared based on the original Chord, the routing perfomence of this system improved...
P2P workflow systems meet the development trend of workflow systems. The running path optimization (the path with the minimum running time which consists of the services discovery time and the task execution time) in full-distribution (decentralized) environments has been a bottleneck restricting the performance of P2P workflow systems. Aiming at this problem, this paper proposes a innovative hybrid...
P2P together with media streaming technology brings a new method for video service. This paper proposes a design to deploy video service on commercial systems with authentication servers. The design combines C/S charging model, and provides video contents in a P2P way. According to the address information registered on authentication servers, a media management server helps new peers to find their...
