Incentives play an important role in BitTorrent-like P2P networks, motivating users to contribute to others to achieve faster average download time for all peers. Recent related studies reveal that two problems remain unresolved in most popular incentive mechanisms for BitTorrent-like systems: (1) incompleteness: contributions are not entirely considered, and (2) unfairness: accumulated contributions...
Firstly, after super-unstructured P2P architecture introduced some super-peers controlled by operation business, a mobile P2P architecture was proposed for streaming media system. And then in this architecture, a receiver-driven bit allocation algorithm was proposed. This algorithm firstly divided the video sequence into a series of blocks where there was the fixed number of frames, and then assigned...
A resource search algorithm gravely affects the performance of P2P system. This paper proposes a probabilistic and exhaustive search algorithm, which has the merits of structured and unstructured P2P system. The topology of system employs a relaxed random multigraph which is scalable. The algorithm firstly evaluates the desired number of replica of data and query by the birthday paradox theory, which...
In recent years, P2P applications are popular and lots of applications are deployed. Because a resource discovered method is important in P2P applications, it attracts much attention from researchers. However, search algorithms face huge challenges of scalability and robustness. Based on the topology of relaxed random multigraph, a probabilistic exhaustive search algorithm for P2P network is proposed...
Decentralized and unstructured peer-to-peer (P2P) network system is becoming one of the most popular file sharing systems on the Internet. Due to its prominent merit, a P2P network becomes an effective distribution channel for selling digital products on the Internet. But there are still many constraints curbing electronic commerce on P2P networks. The main problem is that peers can not get cost-efficient...
