In this paper, a novel P2P network model for cloud computing is proposed to prevent the "calculation capacity" from being controlled by a few tycoons. The common users can become a part of "cloud" by joining as nodes. To solve "free-ride" and "the tragedy of commons" arising from p2p network model, "cloud" is divided into many clusters, and the incentive...
Many P2P systems have been designed without taking into account an important factor: a large fraction of Internet users nowadays are located behind a network address translator (NAT) or a firewall, making them unable to accept incoming connections (i.e. unconnectable). Peers suffering from this limitation cannot fully enjoy the advantages offered by the P2P architecture and thus they are likely to...
With the rapid development of peer-to-peer networks, simulation is considered as a useful tool to demonstrate initial ideas before building prototypes with real network transmissions. In flow-based simulation models of peer-to-peer networks, the algorithm for rate allocation which computes the per-flow rate for several competing flows at each peer in a given network topology is a fundamental component...
Throughput performance of multihop wireless networks is governed by how the network's transport capacity (in bit-meters per second) is partitioned among different network flows. Max-min fair allocation leads to poor throughput performance for all flows because connections traversing a large number of hops consume a disproportionate share of resources. While proportional fair allocation provides a...
